What is a Wiki?

A wiki is a collection of documents that multiple users can edit. Wiki pages can be written in HTML, plain text or a specialized wiki language. On LabKey Server, you can use a wiki to include formatted content in a project or folder. You can even embed live data in this content.

This User Guide will help you create, manage and edit wiki pages. A typical wiki page will show the current page in the main window, an expandable Table of Contents listing of Pages in a column to the right, and a Search box above the Table of Contents.

Navigate Using the Table of Contents

Wiki pages display a Table of Contents (TOC) in the right-hand column, titled Pages, to help you navigate through the tree of wiki documents. You can see pages that precede and follow the page you are viewing, which will appear in bold italics (for this page, Wiki User Guide). Click on a page to open it.

Expand/Collapse TOC Sections. Wiki documents are organized into parent/child page trees. To expand section and view child pages, click on the "+" sign next to a page name. To condense a TOC section, click on the "-" sign next to it.

Expand/Collapse All. You can use the Expand All and Collapse All links at the end of a wiki table of contents to collapse or expand the entire table.

Create or Edit a Wiki Page

To create a new wiki page, click the New link. To edit an existing page, click the Edit link at the top of the displayed page.

This brings you to the wiki editor, whose features will be discussed in the following sections.

Name. Required. The page Name identifies it uniquely within the wiki. The URL address for a wiki page includes the page name. Although you can create page names with spaces, we recommend using short but descriptive page names with no spaces and no special characters.

The first page you see in a new wiki has the page name set to "default." This designates that page as the default page for the wiki. The default page is the page that appears by default in the wiki web part. Admins can change this page later on (see Customizing the Wiki Web Part).

Title. The page Title appears in the title bar above the wiki page.

Index. Uncheck if the content on this page should not be searchable.

Parent. The page under which your page should be categorized in the table of contents. You cannot immediately specify the order in which a new page will appear among its siblings under its new parent. After you have saved your new page, you can adjust its order among its siblings using its Manage link (see the Manage a Wiki Page section below for further details). If you do not specify a parent, the page will appear at the top of your wiki's table of contents.

Body. You must include at lease one character of initial text in the Body section of your new page. The body section contains the main text of your new wiki page. For details on formatting and linking syntax, see:

Render Mode: The "Convert To..." Button. This button, located on the upper right side of the page, allows you to change how the wiki page is rendered. Options:
  • Wiki page: The default rendering option. A page rendered as a wiki page will display special wiki markup syntax as formatted text. See Wiki Syntax for the wiki syntax reference.
  • HTML: A wiki page rendered as HTML will display HTML markup as formatted text. Any legal HTML syntax is permitted in the page.
  • Plain text, with links: A wiki page rendered as plain text will display text exactly as it was entered for the wiki body, with the exception of links. A recognizable link (that is, one that begins with http://, https://, ftp://, or mailto://) will be rendered as an active link.
Please note that your content is not always converted when you switch between rendering methods. For example, switching a wiki-rendered page to render HTML does convert your wiki syntax to the HTML it would normally generate, but the same is not true when switching from HTML back to wiki. Please use caution when switching rendering modes. It is usually wise to copy your content elsewhere as a backup before switching between wiki and HTML rendering modes.

Files (Attachments). You can also add and delete attachments from within the wiki editor.

Add Files. Within the wiki editor's "Files" section below the wiki "Body," click the "Browse" button to locate the file you wish to attach. Within the "File Upload" popup, select the file and click "Open." The file will be attached when you save the page.

Note that you cannot upload a file with the same name as an existing attachment. To replace an attachment, delete your old attachment before adding a new one of the same name.

Delete Files. Within the editor's "Files" section, click the "delete" link next to any file you have already attached in order to delete it from the page.

Display Files. Whenever you add attachments to a wiki page, the names of the files are rendered at the bottom of the displayed page. You must both attach an image and use the proper syntax to make the picture itself visible. Only then will the image itself (not just its file name) appear. To display (not just attach) images, see the "Add Images" section of this page.

Manage Display of the Attached File List. Please see Manage Wiki Attachment List.

Save & Close Button. Saves the current content of the page, closes the editor and renders the edited page. Keyboard shortcut: CTRL+Shift+S

Save Button. Saves the content of the editor, but does not close the editor. Keyboard shortcut: CTRL+S

Cancel Button. Cancels out of the editor and does not save changes. You return to the state of the page before you entered the editor.

Delete Page Button. Delete the page you are editing. You must confirm the deletion in a pop-up window before it is finalized.

Show/Hide Page Tree Button. Located on the upper right of the editor, this button toggles the visibility of your wiki's table of contents (the page tree) within the editor. It does not affect the visibility of the table of contents outside of the editor. The Shown/Hidden status of the page tree is remembered between editing sessions. Hide the page tree to make the editor page render most quickly.

The "Name" of each page in the tree appears next to its "Title." This makes it easier for you to remember the "Name" of links when editing your wiki.

Click on the "+" sign next to any node in the tree to make the list of its child pages visible. Click the "-" next to any expanded node to collapse it.

Use the HTML Visual Editor and Use the HTML Source Editor Tabs. When you have selected "HTML" using the "Render As" drop-down menu, you have the option to use either the HTML Visual Editor or the HTML Source Editor. The Visual Editor provides a WYSIWYG editor while the Source Editor lets you edit HTML source directly.

Quirks of the HTML Visual Editor:

  • To insert an image, you cannot use the Visual Editor. Use the Source Editor and syntax like the following: <img src="FILENAME.PNG"/>
  • To view the editor full-screen, click the screen icon on the last row of the editor.

Manage a Wiki Page

Click the "Manage" link to manage the properties of a wiki page. On the Manage page, you can change the wiki page name or title, specify its parent, and specify its order in relation to its siblings. Note that if you change the page name, you will break any existing links to that page.

You can also delete the wiki page from the Manage page. Note: When you click the Delete Page button, you are deleting the page that you are managing, not the page that's selected in the Sibling Order box. Make sure you double-check the name of the page that you're deleting on the delete confirmation page, so that you don't accidentally delete the wrong page.

Add Images

After you have attached an image file to a page, you need to refer to it in your page's body for the image itself to appear on your page. If you do not refer to it in your page's body, only a link to the image appears at the bottom of your page.

Wiki-Language. To add images to a wiki-language page, you must first add the image as an attachment, then refer to it in the body of the wiki page using wiki syntax such as the following: [FILENAME.PNG].

HTML. To insert an image on page rendered as HTML, you cannot use the HTML Visual Editor. After attaching your image, use the Source Editor and syntax such as the following: <img src="FILENAME.PNG"/>.

Add Live Content by Embedding Web Parts

You can embed "web parts" into any HTML wiki page to display live data or the content of other wiki pages. You can also embed clients dependencies (references to JavaScript or CSS files) in HTML wiki pages. Please see Embed Live Content in HTML Pages or Messages for more details.

View History

You can see earlier versions of your wiki page by clicking on the "History" link at the top of any wiki page. Select the number to the left of the version of the page you would like to examine.

If you wish to make this older version of the page current, select the "Make Current" button at the bottom of the page. You can also access other numbered version of the page from the links at the bottom of any older version of the page.

Note that you will not have any way to edit a page while looking at its older version. You will need to return to the page by clicking on its name in the wiki TOC in order to edit it.

Copy Pages

Warning Once you copy pages, you will only be able to delete them one-by-one. Copy them with great care and forethought. It is easy to duplicate them in the source folder by mistake.

You can copy all wiki pages within the current folder to a destination folder of your choice. Click the "Copy Pages" link under the "Pages" header above the Table of Contents. Then click on the appropriate destination folder. Please note that the source folder is initially highlighted, so you will need to click a new folder if you want to avoid creating duplicates of all pages in the source folder itself. When you have selected the appropriate destination folder, take a deep breath and select "Copy Pages."

Print All

You can print all wiki pages in the current folder using the "Print All" link under the "Pages" header above the Table of Contents. Note that all pages are concatenated into one continuous document.

"Discussion" Link

You can use the "Discussion >" link at the bottom of a wiki page to start a conversation via email or a message board specific to that page. Note that this feature can be disabled at the site level by an administrator, and that when enabled, the role "Message Board Contributor" is required to participate in message board discussions.

Check for Broken Links

You can use ordinary link checking software on a LabKey Server wiki. For example, their are a variety of in-browser plugin in link checkers that work well.

Tips for efficiency in using this link checker:

  • Set it to exclude URLs that represent the execution of common actions on wiki pages. For example, when checking LabKey.org's documentation (at https://www.labkey.org/wiki/home/Documentation/page.view?name=default), paste the following two URLs into the "Do not check any URLs beginning with this:" textbox:
  • Reduce the search depth using the "More Options" button on the page that lets you define the parameters of a search (reached via File -> ). LabKey.org's documentation tree is searched successfully at a "Maximum Level" of 40.
  • Turn off prompts for login certifications when checking a wiki whose content is intended to be public. Using the "More Option" button described above and uncheck the box for "Ask for passwords and certificates as needed."
  • Reduce the Parallel Threads to 10 (from the default 30). This will help reduce the number of false bad link reports due to timeouts.

Add a Link to the Source of a Wiki Page

It is useful to include a "view source" link on wiki pages used to demonstrate the use of LabKey APIs. For example, you will see a "view source" link in the upper right of this API tutorial page.

If you replace the "page" portion of the URL for a wiki page with "source", the URL will lead to the HTML source of the wiki page.

It may also be useful to open a separate page for viewing the source. In these examples, replace "default" with the appropriate page name:

  • Open a LabKey-bordered copy of the source:
<div align="right">
[<a onClick="window.open('source.view?name=default')" href="#">view source<a>]
</div>
  • Open a page that includes only the source, without a LabKey border:
<div align="right">
[<a onClick="window.open('source.view?name=default&_template=none')" href="#">view source<a>]
</div>
