<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.
