<blockquote>Wikis are commonly used for group content development. Semantic Mediawiki adds easier to use forms and the ability to annotate distinct content such as places, people and dates for reuse in interactive views and queries. In this session, we'll look at how semantic wikis can be used to develop content for indigenous and linguistic communities, with a practical, hands on focus including how to create pages, categories and simple ontologies. We will focus on processes to make sites inclusive, and examine fair terms of re-use.

* Anything accepted as notable, neutral point of view
* Careful controls on legal issues so content can be re-used
* Anyone who uses the Internet knows, uses, respects, understands it
* Cultural translations
* Few understand how it's edited
* Designed to be open, but adding controls

On any wiki with critical mass:
 
* Readers
* Drive by editor
* Topic editor

== How to use a wiki ==
 
* Categories
** Many categories, ways of looking at things
** Anyone can manage them
* Recent changes

= Editing wikis =
 
* Wikis typical use their own markup (syntax)
* Rich/wysiwyg editors create messes
** Typical word processors adding junk, can't re-use for headings, can't compare versions
 
== Progressive learning ==
 
* <nowiki>= heading 1 =</nowiki>
* <nowiki>* Bullet point</nowiki>
* <nowiki>[[Wiki link]]</nowiki>
* View source to learn from others
* Edit sections to compartmentalize changes
 
Brackets must be matched!!!!
 
== Elements of markup ==
 
* Headings, bullets, tables, dividers
** HTML code - http://www.asiancanadianwiki.org/wiki/Main_Page
* Links - onsite and off
* Templates
** Consistent appearance and content <nowiki>{{City|Population=30,000}}</nowiki>
