Today, an anonymous person replied to this blog entry. The suggestion is made to cooperate with the SWAD Europe group. They have a website, a blog but it all stopped in 2004. So I am wondering about all these projects, all this effort that just stops. Projects that may be valuable and given that people promote it in 2007, may still be alive. For me there is no way of knowing.
I have an idea how I would use semantic data in OmegaWiki. What I am not so sure about is how semantic web applications would use OmegaWiki data. In essence OmegaWiki is multi-lingual and exporting it in anything but a machine readable version only, would strip what I think is valuable in OmegaWiki.
Collaborating with for instance a SWAD Europe group makes sense. People can suggest cooperation, it should however be a two way street. Just pointing that there are others does not help me much.
Thanks,
GerardM

Extracting semantic information out of omegawiki is not that complex as you might think, because the data is highly structured.
As you may know I know semantic technologies very good and also have my eye on the Semantic MediaWiki.
The first you need is an ontology. That means something that describes basic thinks like word, language, sentence, and the like.
With this you can make statements about an expression. If I get some time I could write some examples how to make such statements properly. Anyway: a layout of the omegawiki database layout may be helpful.
forget about the DB layout - I've found it.
Here is a draft in Notation3. The ontology is not worked out yet, but I think it gives the impression how it might look like.
Here's how the same example might look like in the SWAD/SKOS ontology:
@prefix xml: <http://www.w3.org/XML/1998/namespace > .
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix skos: <http://www.w3.org/2004/02/skos/core#> .
<http://www.example.com/concepts#adventure_758825> rdf:type skos:Concept ;
skos:definition "An exciting or very unusual experience."@en ;
skos:definition "Een opwindende of zeer ongewone ervaring."@nl ;
skos:prefLabel "adventure"@en ;
skos:prefLabel "belevenis"@nl .
More complex examples are possible, see also http://www.w3.org/2004/02/skos/
