[edit] This site was an experiment and as of April 7th, 2009 is no longer accepting changes. It is kept up for archival and reference purposes. New work is ongoing in the direction of having a Pointrel Social Semantic Desktop instead of a Halo Semantic MediaWiki.

Thank you for your interest in project OpenVirgle, OSCOMAK, or SKDB! On this page you will find help for entering or finding wiki information. If you are looking for help with something else, you might want to try the Information Gathering Tips page or OpenVirgle for a project overview. A video on the semantic features can be found here.

Quick Verson

To start a page, search for a title, and when the page comes up stating that it doesn't exist, click on the "create this page" link, or, delete the page name currently in the URL (such as Main_Page or Help) and replace it with the desired title, using underscores instead of spaces (such as Europa_Oxygen_Production). When the page comes up saying the page does not exist, click the "Edit" tab at the top of the window.

Type the desired information in the editing window, using the toolbar above to make titles and links (or manually entering the notation - wiki specific commands are called "WikiText").

Common WikiText commands include:

Symbol Usage
Headers -

placed on either side of text, makes it a heading (<H1>, <H2>, etc.) the more repetitions of the =, the lower the level of the header:

== Level 2 Header <H2> (Big Bold w/ Line) ==

=== Level 3 Header <H3> (Bold w/ No Line) ===
Bold/Italics -

used in sets to make text bolded or italicized

'' Italics ''

''' Bold '''
[ ]
Links -

Links are made by surrounding the link url and the link text in a set of brackets:

Link to page outside of wiki:

[http://www.oscomak.net/wiki/Main_Page OSCOMAK Main Page]

Link to page within wiki:

[[Main Page|OSCOMAK Main Page]]
Lists -

Used at the beginning of a line, makes the line an entry in a bulleted list:

* Bulleted Text
** 2nd Level Bullet

  • Bulleted Text
    • 2nd Level Bullet

Tables are fairly complex in WikiText notation, so edit this page to see how they work. Here is a smaller example, so that the structure is more easily seen:

Column Name Column Name 2 My Favorite Musicians/bands
Row 1, Column 1 Row 1, Column 2 David Bowie
Row 2, Column 1 Row 2, Column 2 Symphony X

Common HTML usage:

HTML is also commonly used in the editor. For example, to write the chemical formula for water one must use the "sub" HTML tag to write the subscript:

→ H2O

All HTML tags are surrounded by "<" and ">", and most have a beginning and ending form, where the eending tag has a slash "/" in front of the tag name.

Generally, WikiText notation is preferred to HTML whenever possible.

Using Semantic Features During Data Creation

This wiki has the halo semantic mediawiki extension. It contains two major tools for adding information that can be used by humans for organizational and querying purposes, and can be read and processed by computers. These are creating properties and categories. To begin using these features, you must log in and click the My Preferences link. Press the skin tab and select OntoSkin. You should probably also click the Misc tab and enable auto-triggered auto-completion.

After this is done, a colorful toolbox containing the categories and Properties tools should be present when you click on the edit tab. To add an article to an existing category press annotate and it will automatically insert the notation for annotating a category. You can also cereate a new category, but pleasse try to avoid this when possible and think ahead to what oveerall categorization would make querying the easiest For example, if you were writting an article on Lithium you would type in "Chemical Element" and press add. You could add additional categories such as "Medications." To add a property, click annotate under properties and enter data into all of the desired fields. The page field shoul usually be the page you are making the property about, and the property should be the name of the property. For programmers, a property is analagous to an object. An example of adding a property would be annotation that the atomic mass of hydrogen is 1.

Making Semantic Queries

To find semantic articles or data, click on the OntologyBrowser button in the toolbox. A list of all categories should be presented. Click on a category to see all articles in that category. Click on an article to see all of its properties. This can save a considerable amount of time and reading. You can use the filter fields to narrow down the amount of results presented. You can also click on the large arrows between boxes to search for articles with a specific property, etc.

You can also use the query interface, but I don't know how.
