If Wikipedia will only have the data but no query (because it's a burden
for its servers), then maybe there should be software on the client to
download the raw data and process the query locally. In some browsers,
even javascript is fast enough for this, so that the browser can fill in

Every once in a while I work up the courage to ask about SMW on
Wikipedia. Is there anything that can be said about plans for this
game-changing event?
Thanks,

Suppose my date property is birthdate. Instead of [[birthdate::not a
date]], I think it be the other way around:
[[not a date::birthdate]]
so that it won't be confused with other property values for birthdate.

Also, SMW can *export* your queries now: click on the RDF feed link on a

In a previous very illuminating message, you said It is very easy to map

What are the plans for exporting compound value types to RDF?
You may be getting into blank nodes.

Good points about the difference between OWL DL and OWL Full.
So if you only want to export OWL DL, what would you do with a page like
the President or Dog or Wine pages on Wikipedia, which are pages about a
class.
Place articles about classes

Sorry, I screwed up this example
What are the plans in Semantic Mediawiki to capture citations? I ask because,
for a cited by property, the subject is not the article, but a particular
assertion made within the article.
For example the article for Germany:
http://ontoworld.org/wiki/Germany
says it has

I have some invitations to get an account on freebase.com (a semantic

You don't need an account to view the data, but you do if you want to change
data or create types.
If you want an invitation, send me email at [EMAIL PROTECTED]
