This page serves as a script for the demonstration of Semantic MediaWiki during the WWW2006 developer's track. You can also find the slides to this demo online . It will be updated during the demo this afternoon. For general documentation of Semantic MediaWiki see Help:Semantics.

[edit] Annotation
First, let's see how one can annotate texts in this wiki in order to make knowledge explicit. Go to RuleML2006.
[edit] Searching
Now how can one access the newly annotated knowledge? By using inline queries. Why not try your own queries in our Sandbox?
- Which things have paper deadlines between June 1 2006 and December 31 2006?
<ask> [[paper deadline:=>June 1 2006]] [[paper deadline:=<December 31 2006]] </ask>
<ask>
>June 1 2006warning.pngThe date ">June 1 2006" was not understood. <December 31 2006warning.pngThe date "<December 31 2006" was not understood.
</ask>
- What are these deadlines, and what are the titles of the events?
<ask> [[paper deadline:=>June 1 2006]] [[paper deadline:=<December 31 2006]] [[title:=*]] [[paper deadline:=*]] </ask>
<ask>
>June 1 2006warning.pngThe date ">June 1 2006" was not understood. <December 31 2006warning.pngThe date "<December 31 2006" was not understood. * *warning.pngThe date "*" was not understood.
</ask>
- OK, now pre-sort this result accoring to deadline.
<ask sort="paper_deadline"> [[paper deadline:=>June 1 2006]] [[paper deadline:=<December 31 2006]] [[title:=*]] [[paper deadline:=*]] </ask>
<ask sort="paper_deadline">
>June 1 2006warning.pngThe date ">June 1 2006" was not understood. <December 31 2006warning.pngThe date "<December 31 2006" was not understood. * *warning.pngThe date "*" was not understood.
</ask>
- Which of the events are also covering Semantic Web query languages in some way?
<ask> [[paper deadline:=>June 1 2006]] [[paper deadline:=<December 31 2006]] [[Category:Topic Semantic Web query languages]] </ask>
<ask>
>June 1 2006warning.pngThe date ">June 1 2006" was not understood. <December 31 2006warning.pngThe date "<December 31 2006" was not understood.
</ask>
- Now also show those events that are about semantic interoperability?
<ask default="Sorry, no results"> [[paper deadline:=>June 1 2006]] [[paper deadline:=<December 31 2006]] [[Category:Topic Semantic Web query languages||Topic semantic interoperability]] </ask>
<ask default="Sorry, no results">
>June 1 2006warning.pngThe date ">June 1 2006" was not understood. <December 31 2006warning.pngThe date "<December 31 2006" was not understood.
</ask>
[edit] Semantic templates
Templates can further simplify annotation and searching, such as Template:person and Template:paper URL.
[edit] Reuse and interoperability
Now how can external applications benefit from the data in the wiki? Via RDF export. An example of an external SPARQL service that allows querying a snapshot of this wiki's data is found at http://dannyayers.com:5555/snorql/.
