Hi Denny yes, we made some progress, see [1] (there is also another proposal User:Ck3d is actively working on, see [2])
Actually, I'd like to have a semantically enabled copy of OSM available for testing. I got in touch with User:Firefishy [3], the OSM wiki admin, but he seems to be offline since ~ two weeks. Meanwhile, other OSM users and myself have run some tests in the SMW sandbox [4]. I'd be glad if we had an SMW instance *including* a snapshot of the current OSM wiki around for further tests. Any help would be appreciated!

Yaron offers hosting of Semantic MediaWikis, and I wanted to connect you in case that makes sense and if you need help or a place to run a semantically enabled copy of OSM for testing purposes. Could make a lot of sense :) If you have more questions, feel free to ask us. If there's something I could do I could take a look at it (just my time is quite constrained, as I am currently in thesis-writing-mode) Cheers, denny Karl Guggisberg wrote: > Hi denny > > I had a second look at the documentation and I now understand how Semantic > MediaWiki can help us. > > Assume map features were described by three attributes: a key, a value and a > description, like > {MapFeature key="foo" value="bar" description="desc"} > > Then we would create a Wiki page [[Tag:foo=bar]] (as we do today): > > ----------- beginwiki of [[Tag:foo=bar]] bla bla bla > > <!-- the properties of Semantic MediaWiki --> [[key::foo]] > [[value::bar]] [[description::desc]] > ----------- endwiki > > On the [[Map Features]] page we could ask for this data (the following > example automatically creates a table, we have full control over > rendering using wiki templates, if we want to) > > ----------- #beginwiki of [[Map Features]] > {{#ask: [[Tag:foo=bar]] > | ?key = Key > | ?value = Value > | ?description = Description > }} > ----------- #endwiki > > > On yet another page we could include information about the map feature: > > ----------- #beginwiki of [[Yet another page]] The map feature > [[Tag:foo=bar]] is described as follows: > * Key: {{#show: Tag:foo=bar | ?key}} > * Value: {{#show: Tag:foo=bar | ?value}} > * Description: {{#show: Tag:foo=bar | ?description}} > ----------- #endwiki > > > I'd like to use SemanticWiki for the OSM wiki.
