Bloomsbury Colleges Wiki
What is a wiki?
A Wiki is a collection of web pages, or 'articles' in wiki terminology, to which anyone can contribute, either by adding new articles or by editing existing ones. This dedicated wiki is created for the use of Bloomsbury Colleges members of staff only. Viewing access has been restricted to Bloomsbury Colleges IP address ranges and anyone wishing to edit pages, create new pages or contribute discussion items will need to login to the Wiki, having first created an account.
If you have never used a Wiki before try visiting the Wikipedia site. This wiki is using the same 'MediaWiki' software, available from www.mediawiki.org and it consists of a MySQL database and a set of PHP scripts running within an Apache webspace.
Adding new articles
A key point to note is that there is no underlying directory structure to the wiki site. All articles are created at the top level, which is http://wiki.bloomsbury.ac.uk/home/, by adding the article name, for example 'Wireless_networking' or 'User_Registration', to the URL within your browser, as in
If 'Wireless networking' does not exist you will get the message:
Wireless networking There is currently no text in this page, you can search for this page title in other pages or edit this page.
When you click on 'edit this page' an editing window will open where you can type in the content. Page text is formatted using Wiki markup which is a form of structured text and the basics are very simple. As soon as you click the 'Save page' button the page is visible to all.
Wiki 'Categories' are the primary method for grouping articles together by subject area. You add category tags to an article when creating or editing it and you can either create new categories or use existing ones. A single article can have several Category tags.
To add a page to the 'Help' category, you would add the following Wiki markup snippet to the end of your article:
This will appear at the end of the the page as a link to the 'Help' Index page which lists all articles within that Category. Category: Help
Adding a Category tag will automatically create an index page for that category if it doesn't already exist. Category index pages can be edited in the same way as articles and if you create a new Category it is a good idea to add a brief description to the index page so that other people know what should be found there.
Viewing All Categories
To see all the categories on the site go to the URL:
Creating subcategories takes only a few additional steps. Adding a category tag to a category page makes the edited category a subcategory of the category specified in the tag.
First create a new category page for the subcategory the same way you would make a regular category. For example, create Soccer with the tag [[Category:Soccer]].
Then go to the newly created category page and edit it. Add the category tag for the parent category (e.g. [[Category:Sports]]) to the Soccer page.
In this example, the Soccer category would then be a subcategory of the Sports category.
For more detail on Categories see the Wiki Handbook entry Help:Category
'Talk' or 'discussion' pages are intended for users to add comments about the associated article page. A lot of people find this less intimidating than editing the content page directly. To create or contribute to a parallel 'Discussion' or 'Talk' page associated with a particular article, click on the discussion tab at the top of the article. Then click on the + sign in the tab next to the 'edit' tab to add a comment to the discussion. Using the + sign instead of the edit tab is a safer option that avoids the possibility of deleting page content by mistake.
The Categories list is one of several 'Special' pages which can be accessed from the sidebar toolbox link 'Special Pages' and referenced by URLs of the form http://wiki.bloomsbury.ac.uk/home/Special:xxx. To see all available Special Pages go to
Useful special pages include the File list, which shows the names of all uploaded image files, available for adding to your own pages, and the User list showing all registered user accounts in the database, with their group settings).
First you need to know the filename of your image. You can access a list of available image files on the system from the Special page File list or you can upload a new image via the Upload file toolbox link on the sidebar.
To add it to your page use the following Wiki markup snippet:
Linking to Uploaded Files
This Wiki will allow you to upload non-image file types such as Word, Excel or PDF. Upload such files in the same way as images, via the Upload file toolbox link on the sidebar.
To find out an existing filename to link to access a list of available files on the system from the Special page File list . No path information is needed for the link other than the filename as it appears in the list (that is, use spaces not underscores if the filename includes spaces).
To link to uploaded files other than images use the following markup:
[[Media:filename.pdf]] [[Media:file name containing spaces.pdf]]
- Internal links
To add an internal link, enclose the name of the page you want to link to in double square brackets. When you save the page, you'll see the new link pointing to your page. If the page exists already, it is displayed in blue, empty pages are displayed in red. Selflinks to the current page are not transformed in URLs but displayed in bold.
The first letter of the target page is automatically capitalized and spaces are represented as underscores (typing an underscore in the link has the same effect as typing a space, but is not recommended).
