FDA MyStudies: Technical Setup Document


This documentation covers the technical setup for the components that make up the FDA MyStudies Mobile Application System. This top level page gives a broad overview; details for each component are covered on linked pages. The system components are:
  • the Registration Server where participants sign up and create an account (UserReg-WS)
  • the Mobile Client App into which participants enter data (Android or iOS)
  • the Response Server which handles and stores the responses sent by the Mobile App (Response)
  • the Web Configuration Portal where administrators design research questionnaires (WCP and WCP-WS)
The GitHub repository for this open source project is here:

Sections

1 Introduction

This documentation provides deployment instructions for the FDA MyStudies platform open-source code present in the FDA-MyStudies GitHub repository. It serves as a deployment guide for technical teams and explains how the different components of the platform can be set up and used.

2 High-Level Technical Architecture

Web Configuration Portal (WCP)

The Web Configuration Portal is a web-based application that provides mechanisms to create and manage content for studies that can be made available to patients/participants via the mobile apps. It also offers corresponding "Study Metadata" webservices to the mobile apps, and to the Response server that holds the data or "responses" provided by participants due to their participation in the mobile-app based study.

The WCP application is built on Java.

The WCP allows you to:

  • Manage WCP users (also referred to as Admins, WCP ‘users’ would typically be researchers, clinicians, or study administrators involved in carrying out a study)
  • Manage app-level notifications
  • Create new studies or view/edit existing ones
  • Set up:
    • Study information and settings
    • Eligibility and informed consent modules
    • Study activities (surveys or questionnaires, and active tasks)
      • This includes setting up activity content and schedules
    • Study resources for each study
  • Send out study-specific push notifications
  • Take actions with a study such as launch study, publish updates, deactivate, etc.
Push Notifications:

Notification content created in the WCP is sent over to the User Registration Server, whose web services are utilized for the same. The User Registration server then actually sends out the notification to mobile app users, who are the intended audience for the notification.

User Registration Server

(Here ‘User’ refers to the mobile app user or study participant)

The User Registration server is built on the LabKey framework. It leverages LabKey’s User and Registration modules to provide registration services to mobile app users. It helps manage the mobile app user’s app activity and maintains the user’s app usage and study participation metadata. This server, however, does not contain any actual study ‘Response’ data (Response data is saved in the Response server against an anonymized Participant ID).

The User Registration server is thus primarily used for the following:

  • User registration (handling app sign up and sign-in related flows)
  • User profile and app-level preferences
  • User’s app usage and study-specific participation metadata (study participation status, activity completion status, etc.)
  • Firing push notifications to the mobile app users

Mobile Applications

  • FDA MyStudies comprises iOS and Android mobile apps intended for study participants to use. These apps help capture study data from participants via surveys and active tasks, after taking them through a process of testing their eligibility to participate in the study, and providing electronic informed consent.
  • The iOS app leverages Apple’s ResearchKit framework and the Android app leverages ResearchStack to present studies for users to enroll and take part in.

Response Server

The Response server is built by LabKey. It is the data store for the responses captured from mobile app users. It also provides access to this data to authorized members of the research team, for analysis purposes.

The Response Server thus primarily facilitates the following:

  • Participant enrollment into a study
  • Response data storage
  • Access to the Response data for analysis

Multiple Language Support

When you configure a study, you have the option to elect whether to support multiple languages for the user. Beginning with version 21.10 (October 2011), English is the default and Spanish language is also supported.

Note that all administrative actions for setting up the study and resources for researchers/data analysts will be presented in English. The multiple language support applies only to the information and messages shown to the user of the mobile app.

Administrators can Enable Multiple Language Support when defining a study on the WCP, providing both English and Spanish question and answer options. For studies with both defined, the version supplied to the user will be determined by the settings on the mobile device.

If a language other than Spanish is selected on the device, the questions and responses will default to English.

8 Create Your Study on WCP and Run

Once you have set up all the different components and applications of the MyStudies solution, you are ready to create your study via the WCP, publish it to the mobile app, and run through the user flow of a study participant who would use the mobile app to participate in the study. Given below is a high-level description of the process you would need to employ for the same.

8.1 Create the study in WCP

Details for creating a new study in the WCP are covered in this topic:

Once that process is complete, continue as follows:

8.2 App and Study Folder in User-Reg Server

Since the MyStudies application supports multiple apps, the User-Reg Server should hold its data accordingly. So before publishing the study from WCP Server, Org Folder, App folder, and Study Folder need to be created in User-Reg Server (REFER SECTION 4.3).

Note: For each app created, users should do a fresh signup since user data is not shared among different applications.

8.3 Create Study on Response Server, and Generate Enrollment Tokens

  • Once your study has been set up on the WCP, and the Response Server is ready too, login to the LabKey admin portal
  • Create your Project.
  • Create your Study space/folder using the same Study ID you used to create the Study in the WCP.
  • Once this is done, enrollment tokens can be created for the Study (if Token Validation method is being used for ascertaining eligibility), these are distributed to users of the mobile app to participate in the study.
(Please refer to LabKey documentation for more details on steps to set up a study on the Response Server.)

8.4 Study Participation using the mobile application

  • Launch the mobile app installed on your phone
  • Sign up with a valid email ID and password and follow the instructions to set up your user account.
    • (Note that mobile app users would need to sign up separately for each of the apps created using the platform.)
  • After successful sign up, if using a gateway type of app, there would be list of studies to choose from (all published to the app using the WCP).
  • Pick a study for which you have the enrollment token and proceed, OR, choose a study that does not require a token to be used but has an eligibility questionnaire/test instead.
  • Participants can search using the enrollment token to find the study that he/she wants to enroll in.
  • To join the selected study, complete the Enrollment Token Validation/ Eligibility steps and the Informed Consent process. This involves reviewing consent sections, taking a comprehension test (if available for the study), completing the legally authorized representative section (if enabled for the study), and then doing a final review of and agreeing to the full Consent Document. The process ends with an e-signature after which the app generates a signed consent document PDF.
  • Once in the study, you can participate in activities listed out as per the schedule in which they are to be taken.
  • You can also view various statistics and trends on the study dashboard and access study resources.
  • There are also other miscellaneous features at the app level such as a ‘Notifications’ section, Account/Preferences section, and provisions for participants to provide feedback or contact a designated email inbox for inquiries.

3: WCP and Webservices Setup


This topic is under construction.

This topic covers how to set up the WCP and WCP-WS web services. This is section 3 of the overall setup process covered in: FDA MyStudies: Technical Setup Document.

3.1 Installation Required

Prior to installation, the following setup is required:

3.1.1 Java 8

The link below gives instructions for installing the JDK and JRE on Oracle Solaris, Windows, Linux, and OS X computers.

3.1.2 Tomcat 8

The link below will help you download and install Apache Tomcat and use many of the Apache Tomcat features

3.1.3 MySQL 5.6 or 5.7

The link below explains how to install MySQL or upgrade an existing MySQL version to a newer version.

3.1.4 Maven

The link below will assist you in installing Maven

3.1.5 Git Repository

Source code for WCP application and Web Services is available at:

3.2 Configuration

3.2.1 Initial Configuration

HPHC_My_Studies_DB_Create_Script.sql: This script file should be executed in MySQL. It is found inside the sqlscript folder at this path:

hphcAuditLogs: This folder should be created inside the server and the path should be configured inside application.properties for fda.logFilePath parameter.
  • Example: fda.logFilePath=/usr/local/hphcAuditLogs/

3.2.2 Properties Files

The template_application.properties file should be downloaded from the WCP folder of the GitHub MyStudies repository and renamed to application.properties and stored in the system/server. Make necessary changes in the file based on your application configuration. The file path is given below:

Changes in Tomcat Configuration File:

Below are the changes required to the Tomcat context.xml file which can be found at:

  • <tomcat installed path>/tomcat/conf/
Add these parameters in the context.xml file inside <context> tag.
<Parameter name="property_file_location_prop" value="/usr/local/" override="1"/>
<Parameter name="property_file_name" value="application" override="1"/>
<Parameter name="property_file_location_config" value="file://usr/local/application.properties" override="1"/>
<Parameter name="property_file_location_path" value="/usr/local/application.properties" override="1"/>

messageResource.properties: This file for web application is available at /src/main/resources folder inside the project directory. Make necessary changes in the file based on your application configuration.

3.2.3 Bundle Id and App Token Settings

authorizationResource.properties file for web services application can be found at /studyMetaData/src/main/resources folder inside project directory. These are the changes required:

{Unique Identifier}=android.apptoken	#Unique Android identifier.
{android bundleid}=android.bundleid
{Unique Identifier}=ios.apptoken #Unique iOS identifier.
{iOS bundleid}=ios.bundleid
{Unique Identifier}=labkey.apptoken #unique LabKey response server identifier.
{LabKey Unique String}=labkey.bundleid

bundleID and AppToken are the security parameters used for communication between WCP-WS and other applications.

  • bundleID: the unique identifier for the authentication of client applications (e.g., Android, iOS, LabKey response server).
  • AppToken: You have to create three AppTokens, one for each application, to communicate with WCP-WS. You need to create an AppToken, one each for Android, iOS, and the Response server, the three applications that communicate with the WCP-WS. Once the AppToken is created, all the communications will take place through this unique token. If a request originates from any other application, the authentication will fail.
  • Mobile web services communication should take place through the bundleID and AppToken.

3.2.4 Set Super Admin Email ID

HPHC_My_Studies_DB_Create_Script.sql file can be found at https://github.com/FDA-MyStudies/WCP/tree/develop/sqlscript and update "your email address" text in HPHC_My_Studies_DB_Create_Script.sql file with the email id that you want to keep as super admin for WCP application. Use forgot password functionality to set a password.

3.3 Build

To build the application(s), run the command given below from the project root folder(s):

mvn clean install

3.4 Deployment

Once the build is successful, the .war files will be generated in the target folder. To deploy, copy these .war files and paste them inside the ‘webapps’ folder of the Tomcat installation path and restart the server.

If your StudyMetaData project is created with StudyMetaData-0.0.1-SNAPSHOT.war name, change the file name to StudyMetaData.war before deploying to the Tomcat webapps.

3.5 Test the Application(s)

After deploying the builds, hit the following URLs to verify the application status:

Web application:

http://localhost:8080/fdahpStudyDesigner	# NOTE: In place of localhost:8080, use your configuration.
This will redirect you to the login page. Use forgot password to change the password for the email id you have provided in step 3.2.4 and use the new password to login into the application.

Web services:

http://localhost:8080/StudyMetaData/ping	# NOTE: In place of localhost:8080, use your configuration.

This will display “It Works!”

4: User Registration Web Services


This topic is under construction.

4.1 Getting Started

The User Registration web services are built on the LabKey environment. To start this project, you need to set up a LabKey development machine. The link given below will guide you through this process:

Once the LabKey development environment is set up, clone the GitHub repositories such as 'UserReg-WS' into the /server/modules folder. (If checked out into a different folder/name please update path in settings.gradle, build.gradle of distributions folder and commands accordingly.)

Switch to the primary branch and then do a git pull.

4.2 Build

4.2.1 User Registration Web Services

In your settings.gradle file, find the commented out lines with this text:

// The line below is an example of how to include a single module
//include ":server:modules:workflow"
Underneath this line, add these two lines:
include ":server:modules:UserReg-WS"
include ":server:modules:UserReg-WS:distributions:Registration"

To generate a local build, use the below command:

gradlew cleanBuild deployApp

Once the build is successful, click the icon in your IDE.

Use this link to ping the local server after it is started, to verify that the web services are running locally:

http://localhost:8080/labkey/fdahpUserRegWS/ping.api

To open the LabKey home page of the (local) User Registration server, use:

To generate a production build, use the following commands:

gradlew deployApp -PdeployMode=prod
gradlew -PdeployMode=prod :server:modules:UserReg-WS:distributions:Registration:distribution

Once the build is completed, you will find the distribution file at the path given below, where <LABKEY_HOME> is the root folder where you have cloned the LabKey code:

  • <LABKEY_HOME>/dist/Registration
To deploy the UserReg-WS module to the production server, please refer to:

4.3 Multiple App Support

The MyStudies platform supports multiple apps with a single deployment. The User-Reg server follows a specific project and folder structure (Org project, App folder, and Study folder) to handle all the data accordingly:

  • A Project named for the Organization (OrgID) with
  • A Folder inside it for each App (AppID) plus
  • One or more Study folder(s) within these (StudyID).
The data is sent by the mobile application to the specific Study folder that matches this three level naming structure.

4.3.1 Folder Creation

The following steps describe the folder creation process for the user registration server. The folder hierarchy to be followed is: Org folder -> App folder -> Study folder.

The App folder will hold all the app-level data, and the Study folder will store all the study-level data. The Org folder helps identify the organization to which the apps and inherent studies belong. Users can be assigned permissions to the various hierarchies of folders, as required, using the LabKey user management features.

Note: For the User-reg server to handle App & Study level data, the following steps need to be followed before publishing the study:
  • Folder creation: If a study with a new OrgId and AppId is created in WCP server, then the Org, App, and Study Folders should be created on the User Registration server, with OrgId, AppId, and StudyId as the names respectively.
    • If a study with an already existing AppId (and thus OrgId) is created in WCP server, then only the Study Folder needs to be created within it.
    • Note that for a production/live environment (as well as a staging environment) access to data can be restricted as required by controlling access to the server and user permissions on the LabKey folders.
    • Also note that there is no change required in the folder creation process on the Response Server.
  • Firing App Properties API: More about this is given in the last part of this document.

Following are the steps to create the folders in the User Registration server and steps to view the data on the server:

Step 1: Create a project for the organization if one does not already exist. The name must be the same as the value of OrgID used on the WCP. Choose folder type "Collaboration" and accept other defaults.

Step 2: Select (Admin) > Folder > Management, click the Folder Type tab and make sure that the FdahpUserRegWS module is checked.

Step 3: Still in the folder management section, click the Module Properties tab and add the OrgID as used on the WCP in the value of StudyId for the new project you just created, also named with the "OrgID" used on the WCP. Save this change.

Step 4: In the project, create a subfolder to hold all the data for this app - each organization may have one or more AppIDs in use on the WCP. For each one, you need a folder named the same as the "AppID". Use the "Collaboration" type and accept other defaults.

Step 5: Select (Admin) > Folder > Management, click the Folder Type tab and make sure that the FdahpUserRegWS module is checked. Click the Module Properties tab and add the AppID of the application in the value of StudyId for the new folder you just created, also named AppID. Save this change.

Step 6: Next, within the AppID folder, create a subfolder to hold all the study level data. The name of this folder must be the same as the "StudyID" used on the WCP. Use the "Collaboration" type and accept other defaults.

Step 7: In the new folder, select (Admin) > Folder > Management, click the Folder Type tab and make sure that the FdahpUserRegWS module is checked. On the Module Properties tab, enter the StudyID value used on the WCP as the value of StudyId for the new folder also named the same StudyID value.

Step 8: To view the data, create external schemas. Select > Developer Links > Schema Browser. Click Schema Administration, then New External Schema.

Step 9: Enable the below tables in the schema to view app level data (i.e. at the AppID level):

  • apppropertiesdetails
  • authinfo
  • loginattempts
  • passwordhistory
  • userappdetails
  • userdetails

Step 10: Enable the below tables in the schema to view study level data (i.e. in the StudyID subfolder):

  • participantactivities
  • participantstudies
  • studyconsent

Step 11: Add a Query web part and choose the schema to view the data. Add a Files web part to view the associated files. Do this at both the project level (App level data) and subfolder level (Study level data). The two levels are shown below:

4.3.2 App Properties API

If a new app is created in the WCP server, i.e., if a new App ID is introduced, then the following API should be called manually before publishing the study and after creating the Org, App, and Study level folders in the User Reg server. This API helps to populate the user registration server with app-specific data and files required to operate the mobile apps. Please ensure the API is loaded with values as applicable to your app.

Note that the platform will be enhanced in the future to provide an interface in the WCP for managing such app-level properties and content and automating the transfer of these values to the user registration server with the API. That is one of the objectives of the MAMO feature.

The API’s generic template is provided below for reference:

POST: {Base url of user-Reg-WS}/fdahpUserRegWS/appPropertiesUpdate.api Content-Type: application/json { "appId": "", // app ID

"orgId":"", // org ID

5.9 Next Steps

Continue with set up in the main document.

Appendix: Build at the Command Line

It may be desirable to build your MyStudies iOS app at the command line (rather than in the GUI of Xcode) as with CI/CD or other automation. This next section will serve as a brief overview and basic example of building and testing the iOS app using the Xcode CLI tool "xcodebuild". Refer to Github Actions configuration (.github/workflows/Build-iOS.yml) in the repo when configuring similar CI/CD automation on other platforms.

For the purposes of code validation, valid iOS code-signing is not necessary. Building with valid code-signing falls outside the scope of this guide.

These instructions assume Xcode 11 is being used from /Applications/Xcode_11.X.app.

Appendix.1 Set Xcode Code-Signing Environment Variables

The primary purpose of these is to disable code-signing:

export CODE_SIGN_IDENTITY=''
export CODE_SIGNING_REQUIRED='NO'

Appendix.2 Set Xcode Architecture Environment Variable

The following environment varaible limits the code to being compiled only for the CPU architecture of the machine running Xcode and is desirable to avoid building for iOS device architectures for the purposes of code validation:

export ONLY_ACTIVE_ARCH='YES'

Appendix.3 Change to the "HPHC" Directory Within the Repo

Some steps of the build process assume that you are in the "HPHC" directory, which is a sub-directory of the root of the repo:

cd HPHC

Appendix.4 Build

To build, use xcodebuild from the HPHC directory. You may need the full path to xcodebuild, and must substitute your platform, OS, and name settings in the -destination argument:

/Applications/Xcode_11.7.app/Contents/Developer/usr/bin/xcodebuild clean build -workspace HPHC.xcworkspace -scheme HPHC -destination "platform=iOS Simulator,OS=13.7,name=iPhone 11"

If you are using a GitHub Actions config instead of including the specific versions in the command string you could define a "matrix.destination" such as:

strategy:
matrix:
destination: ["platform=iOS Simulator,OS=13.7,name=iPhone 11"]

Then run, using syntax like:

xcodebuild clean build 
  -workspace HPHC.xcworkspace 
  -scheme HPHC 
  -destination "${{ matrix.destination }}"

Appendix.5 Test

xcodebuild test 
            -workspace HPHC.xcworkspace 
            -scheme HPHC 
            -destination "${{ matrix.destination }}"

6.8 Next Steps

Continue with set up in the main document.

Appendix: Build at the Command Line

It may be desirable to build your Android app at the command line, particularly for use with automation. This next section will serve as a brief overview and basic example of building and testing the app in this way.

The Android app repo uses gradle to execute builds. Gradle operates on a self-bootstrapping basis, meaning that you do not specifically need to install gradle beforehand, as gradle will take care of "installing itself" the first time you run the build. Other LabKey projects also use gradle, and you can learn more about using gradle with LabKey in this section of the LabKey Server documentation (opens in a new tab): Gradle Build Overview

Setting up to build on Windows is not covered in detail in this guide.

Appendix.1 Set Up the Android SDK

You'll need the Android SDK from either the "Android Studio" desktop app or the "commandline-tools".

Ensure that the Android SDK license is accepted. The license acceptance process is specific both to the OS you're using and to how you installed the Android SDK. And as such, is not specifically covered by this guide. You will need to have accepted the Android SDK/Android Studio licenses to proceed.

  • Attempting to build without accepting the licenses results in error messages like the one below:
    You have not accepted the license agreements of the following SDK components: [Android SDK Platform 23, Android SDK Build-Tools 23.0.1]. Before building your project, you need to accept the license agreements and complete the installation of the missing components using the Android Studio SDK Manager.

Appendix.2 Ensure Gradlew is Executable

Building is done using the gradlew script. On platforms other than Windows, to ensure this script is executable, run:

chmod a+x ./gradlew

As with most gradle projects, you can use the following command to see what tasks are available in this repo:

./gradlew tasks

Appendix.3 Set Environment Variables

Set the $ANDROID_HOME environment variable. The value of this environment variable is specific both to the OS you're using and to how you installed the Android SDK. Determining the path to your Android SDK is not covered by this guide.

Ensure that the $JAVA_HOME environment variable is set correctly. At time of writing, this repo expects to use JDK version 1.8/8

Running ./gradlew build without setting the $JAVA_HOME environment variable results in error messages like the one below:

FAILURE: Build failed with an exception.

* What went wrong:
Could not create an instance of type org.gradle.initialization.DefaultSettings_Decorated.
> Could not initialize class org.codehaus.groovy.runtime.InvokerHelper

Appendix.4 Configure Code Signing for the App

Code signing for the app must be configured. Learn more in the official documentation on the Android developer site:

Appendix.5 Build the App

If your goal is simply to determine if the project builds at all, you can now run gradle with ./gradlew build without filling in apikey.properties.

  • You'll find the resultant .apk files under the app/build/outputs/apk/fda/debug and app/build/outputs/apk/fda/release directories.
  • These .apk files are explicitly untracked in the repo as is common for binary artifacts, so you won't see them in git status after building them.
If your goal is to build a configured and functional app, you will need to fill out the apikey.properties file similar to Step 6.4.1 above before running the build with
./gradlew build

7: Response Server Setup


This topic explains how to set up the response server to begin collecting data from the mobile apps. This is section 7 of the overall setup process covered in: FDA MyStudies: Technical Setup Document. Each data partner owns a project on LabKey Server, and each study resides in a different subfolder of the parent project. After a participant completes a survey, the mobile application sends the response to the server where it is stored in the appropriate study subfolder.

Enrollment is accomplished by the use of enrollment tokens. A set of enrollment tokens are generated for a given study and distributed to prospective participants as tickets for enrollment in that study. Upon successful enrollment, the server provides the mobile client with a globally unique application token, which the server uses to identify the appropriate study folder and participant on all subsequence communications.

Create a Project

If you are adding a study to an existing project, navigate to that location. A site administrator can create a new project, typically named for the app or organization performing the studies.

  • Create a new project on the server. The project will serve as the parent container for the study subfolders.
  • Choose folder type "Collaboration".
  • For now, leave the permissions limited to your own user ID until you have correctly configured the folder. See below for how to add additional authorized users.

Create a Subfolder

Within the project:

  • Create a new folder of type "MyStudies Response".
  • For now, leave the permissions limited to your own user ID until you have correctly configured the folder. See below for how to add additional authorized users.

If instead you see a "Mobile App Study" folder type, STOP and use the older-interface documentation for this section here: Previous UI for Response Server Setup

In your new folder, you will see the MyStudies Response Server panel, which will guide you in setting up your study, then provide a quick view dashboard of the configuration to others.

Response Server Site Settings

A one-time setup step for the Response Server is for a site administrator to connect it to the WCP, or otherwise provide metadata for testing. This configuration was previously done using module properties with similar names.

If you see a message in the MyStudies Response Server panel like the following:

Response Server Site Settings are not configured. Click here to configure them.

  • Click the word "here" to configure.
  • A site administrator can also directly access this page via (Admin) > Site > Admin Console > Configuration > Response Server Configuration.

Configure how to load metadata. An option to load metadata from files is provided for local testing. For operational servers, you'll use Load metadata from WCP server.

  • Provide:
    • WCP Base URL: The base URL for the Activity Metadata service. Should be an absolute URL that ends with /StudyMetaData. Note that this URL must NOT end with a question mark.
    • Username: The username to use to authenticate against the WCP server, NOT the Response Server.
    • Password: The password for that username on the WCP.
  • Click Save And Finish.
Once the site settings are properly configured, the message will no longer be shown in the MyStudies Response Server web parts.

Local Testing File Option

If you want to use the Load metadata from files (used for local testing) option, provide the directory on the server that holds the survey design metadata files. These metadata files should be of the form <studyId>_<activityId>_<version>.txt.

Study Setup

Once the site settings are configured, you can configure the study folder itself to collect the correct responses.

Set Study ID

  • In the MyStudies Response Server panel, you'll see a red indicating the study needs to be configured. Click either "Study Configuration" or the word "here" in the message to configure it.
  • You will now be on the MyStudies Response Server tab of the (Admin) > Folder > Manage page.
  • Enter the StudyID value exactly as it appears on the WCP. In concert with the site settings you entered above, this will route the expected responses for this study to this folder.
  • Check the box for Enable Response Collection. This makes the study open for enrollment and able to store response data.
  • Click Save.
Once the configuration is complete, you'll see a green check, indicating the study is ready.

Update Metadata

Click Update Metadata on the Study Setup panel (shown above) to proactively create or update the response schema based on the latest study metadata in the WCP. Note that this step is not required for successful response submission (the response schema is updated automatically when a response indicates a newer version is available), but can assist administrators who wish to pre-populate participant properties or create queries and reports before response data is submitted.

Assign Permission Roles to Users

LabKey uses a role-based system for assigning individual permissions at different levels. Some important roles for the MyStudies system:

  • Site or Project Admin: Can create new users and assign permissions.
  • Folder Administrator: Can generate and view tokens, make changes to folder permissions, add webparts to pages, plus all actions an Editor can do.
  • MyStudies Coordinator: (Coming soon with LabKey release 20.11) This role can be added onto a Reader or Editor role and gives permission to create and view tokens, but none of the other additional permission granted to folder administrators.
  • Editor: Can read/insert/update response data and create new grid views to share with others.
  • Reader: Can read response data and create new grid views for themselves, but not to share.
Permissions are assigned for each container (project or folder) and can be inherited in subfolders. To assign permissions for a folder, select (Admin) > Folder > Permissions. Add users (or project groups of users) to the desired roles.

For example, you might have a team of researchers to assign to the "Reader" role in a given study folder. One, but not all, of these users might also be assigned to a role that lets them generate tokens.

Learn more about assigning roles to users (and groups of users) in this topic: Configure Permissions

Generate Tokens

The data partners distribute enrollment tokens to potential participants.

Permissions required:
  • Currently, the role "Folder Administrator" or higher is required to generate tokens.
  • Beginning with version 20.11 of LabKey Server, users with "Reader" or higher PLUS the new role "MyStudies Coordinator" will be able to generate tokens.

Enrollment tokens are specific to the container in which they are generated. A mobile app attempting to enroll using a token from a different study will not be successful and will receive an error message from the server.

  • In the panel Enrollment Token Batches click New Batch.
    • Note that if you do not have "MyStudies Coordinator" or admin permission, this action will not succeed.
  • In the Generate Tokens pop up dialog, specify the number of tokens to generate. Base your selection on the number participants you expect to enroll. Options:
    • 100
    • 1,000
    • 10,000
    • Other <enter custom number of tokens>
  • Click Submit.
Once tokens have been generated, the admin can review each batch, see at a glance how many were generated, how many have been used, and open each batch to find available tokens for distribution.

Enrollment Test

To test your set up, enroll (and unenroll) a fictional participant, see Testing the Response Server.

Set Module Properties

Certain module properties must be defined in order to know where to retrieve the metadata about the study activities that the server is receiving responses for. This metadata is used to create the schema where the response data is stored. This metadata can be retrieved either from a file on the server or from a service (API). In a production system, the service will likely be used.

  • In your study folder, go to (Admin) > Folder > Management > Module Properties tab.
  • Set the following properties, as appropriate. Note that the following properties can be set at three different container scopes: for the Site as a whole, for the current project as a whole, or for a single study subfolder. Enter your values at the Site or Project level will cause them to applied to any other subfolders in scope. Usually you will want to set these at the Site level.
    • SurveyMetadataDirectory - The directory on the server that holds the survey design metadata files. For use in testing or when the metadata service is not available.
    • MetadataServiceBaseURL - The base URL for the Activity Metadata service. Should be an absolute URL that ends with /StudyMetaData; see example below. Note that this URL must NOT end with a question mark.
    • MetadataServiceAccessToken - App token to be passed in request headers to the Activity Metadata Service to identify this client.
If the last two parameters are not configured, the SurveyMetadataDirectory will be used to find the metadata file. If none of the parameters are configured, an error will be generated. The name of the survey metadata file in the SurveyMetadataDirectory should be of the form <studyId>_<activityId>_<version>.txt.

The following screenshot illustrates using a metadata service for the entire LabKey Server site:

8: WCP - Create New Study


This topic is under construction.

This topic is part of the FDA MyStudies: Technical Setup Document. It covers the details for section creating a new study in the WCP from this point in the setup process.

8.1 Create the Study in WCP

Sign in to the WCP, and click on Studies > Create New Study. Follow the series of steps shown below to set up content for your study.

(The WCP user is referred to as 'Admin' in the sections below.)

Support for Multiple Languages

When you configure a study, you have the option to elect whether to support multiple languages for the user. At present, English is the default and Spanish language is also supported. To enable communication with the end user in the language of their choice, choose Enable Multiple Language Support. When multiple language support is enabled, the Admin will be able to switch between languages for the writing of questions and response options in the sections below.

Note that all administrative actions for setting up the study and resources for researchers/data analysts will be presented in English. The multiple language support applies only to the information and messages shown to the user of the mobile app.

Once questions and response options have been configured in both English and Spanish, the version supplied to the user will be determined by the settings on the mobile device. If a language other than Spanish is selected, the questions will default to English.

8.1.1 Basic information

  • Here, the Admin should enter a Study ID (which should be unique for each study), Study name, Study category, research and data partners, tentative duration, study tagline, study description, etc.
  • Each study that you create will have a Study ID and be associated with an App ID, as well as an Org ID. The App ID and Org ID indicate the mobile app and organization with which the study is associated.
    • The App ID for a study must be configured in the basic information screen (read more about app types and app IDs below).
    • The Org ID field is not supported for configuration via the UI as of now but hardcoded in the backend and mobile apps with a default value. These Org IDs can be updated as required if the studies running on the deployment are associated with different organizations and if you wish to identify studies by the organization at the database level or have other use cases to address based on the Org ID.
  • The platform supports two mobile app models: Gateway and Standalone.
    • Gateway apps are those which house multiple studies, whereas standalone apps are those that have a single study each.
    • Multiple mobile apps of each type (gateway and standalone) can be supported with a single deployment of the platform.
    • Each app created off the platform must have a unique App ID.
  • The Basic Information screen will allow you to specify if your study should belong to a gateway or standalone app.
    • A study thumbnail image should be uploaded for a study being added to a Gateway app; this appears in the Gateway app’s study list screen.
  • You would need to provide an ‘App ID’ for the study in the corresponding field on the Basic Information screen. This identifies the specific app that the study must appear in.
    • If you want to add a study to an existing Gateway app, provide the app's App ID here. If adding the study to a new app (Gateway or Standalone), add a new unique App ID into this field.
    • Note that standalone studies would always need a new unique App ID to be created. Refer to image below:

8.1.2 Settings & Admins

  • Here, the Admin can configure certain settings for the study and manage users or “Admins" who can view or edit the study.
  • Some of the key study settings here are mobile platform(s) supported for the study, enrollment being open or closed for the study, allowing enrollment date to be used as an Anchor Date for scheduling study activities and resources, etc.

8.1.3 Overview

  • In Overview, the Admin can add multiple pages for a study, reflected in the mobile app under Study Overview screens.
  • Each page contains a Title, Description, and Image. Admin can also add a study video URL on the first page of the Study Overview.

8.1.4 Eligibility

  • In the Eligibility section, the Admin can choose and set up content for the desired method to be used for determining participant eligibility:
  • Token Validation Only
  • Token Validation and Eligibility Test
  • Eligibility Test Only.
Once the study is launched, then the Admin will not be able to edit the Eligibility type.

8.1.5 Consent Section

  • In Consent Sections, the Admin can add ResearchKit / ResearchStack based (pre-formatted mobile UI) or custom consent section types and fill in the content accordingly.
  • Each consent section contains a title, display title, summary, and elaborated content.
  • The admin can also choose to display the consent section as a visual step in the mobile app.
  • The admin can allow participants to take a comprehension test of the consent material and set up comprehension test questions and a minimum score to pass the test.
  • In the Review Consent screen, the Admin can either choose from the auto-generated consent document (Concatenated Consent Sections) or create a Custom consent document to be used in the app.
  • Consent by a LAR (Legally Authorized Representative): This will add functionality to the study's consent module in the mobile app to allow the app user to provide consent on behalf of the participant as a LAR. The study will continue to support direct consent even if this setting is enabled. The app user can choose one of two consent methods as applicable to them and will be guided through the rest of the app's consent process accordingly.
  • Additional signature lines for study staff: This feature will enable additional signature lines in the finalized PDF document to accommodate required study staff signatures.

8.1.6 Participant Properties

  • The admin can create external properties that can define Anchor dates for activities, tasks, or resources.
  • This is not a mandatory step to create the study.

8.1.7 Study Activities – Questionnaires

  • The admin can create questionnaires with a combination of Instruction Steps, Question Steps, and Form Steps.
  • Each question step comprises Step-level, Question-level, and Response-level attributes that offer several provisions to design the kind of questionnaire and study experience you need.
  • A Form Step is essentially a set of Question Steps in the mobile app; all questions that belong to a form appear on a single screen.
  • Many scheduling options are provided that the admin can choose from to determine the schedule of the survey in the mobile app.

8.1.8 Study Activity – Active Tasks

  • The Admin can choose to add active tasks to the study from the options available in the WCP.
  • Once an active task is selected, the admin needs to fill in values for its configurable attributes.
  • A number of scheduling options are provided that the admin can choose from to determine the active task schedule in the mobile app.

8.1.9 Resources

  • The Admin can add resources’ content either using a text editor or by uploading a PDF. These resources will be reflected in Mobile app in the Resources section of the study.
  • Resources can be made available in the app for specific time periods using the Period of Visibility settings. There is also a provision to notify mobile users when a new resource is available.

8.1.10 Notifications

  • Admins can create and send study-specific push notifications to participants
  • Notifications can either be sent out immediately or scheduled for a date and time.

8.1.11 Actions

  • In this section, the admin sees the various actions that can be taken with a study.
  • Admins can choose to publish the study as test mode or live mode. Each mode can be published as an upcoming one, launch the study to enroll participants, collect data, publish updates ongoing to existing studies, or Pause/Resume or deactivate them.
