Hi Sean
There are still plenty of things to address before the subject can be considered "done". Follow the United Nations Group of Experts on Geographical Names and the EuroGeoNames implementation. In EGN <http://www.eurogeographics.org/eurogeonames> we pursued one data model that met with European requirements under the INSPIRE dm, but 1) this changed and 2) many of the feature types and values that would make the best gazetteer are simply not captured by the main data providers. EuroGeographics continue this work with the Finnish Geodetic Institute. The proposal now favoured will follow the OGC gazetteer profile (as I understand it).

Do you think that's still a valid conclusion? Should schema.org be advised to stay away from this area?

Pretty tough, http://schema.org/Landform has Volcano and Continent but no island. Are there standard medium-sized lists of expected values we should be using here? >From Geonames.org: ISL island a tract of land, smaller than a continent, surrounded by water at high water ISLET islet small island, bigger than rock, smaller than island. ISLF artificial island an island created by landfill or diking and filling in a wetland, bay, or lagoon ISLM mangrove island a mangrove swamp surrounded by a waterbody ISLS islands tracts of land, smaller than a continent, surrounded by water at high water ISLT land-tied island a coastal island connected to the mainland by barrier beaches, levees or dikes ISLX section of island ISTH isthmus a narrow strip of land connecting two larger land masses and bordered by water Ok so picking from http://schema.org/Place ... let's go with http://schema.org/TouristAttraction. Maybe we'll describe the island, and then use Place's containedIn relation to describe the city (also called Korcula) that's on the island. So, it's a thing of type http://schema.org/TouristAttraction ... it has a 'geo' property pointing to a thing that is of type http://schema.org/GeoShape ... which in turn has a 'polygon' property whose value is the Text, "17.052154541015, 42.984695434571 17.108459472656, 42.969589233399 17.140045166015, 42.962722778321 17.166137695312, 42.942123413087 17.181243896484, 42.929763793946 17.212829589844, 42.922897338868 17.208709716797, 42.898178100587 17.177124023437, 42.898178100587 17.090606689453, 42.895431518555 16.964263916015, 42.911911010743 16.839294433594, 42.87208557129 16.833801269531, 42.888565063477 16.732177734375, 42.895431518555 16.725311279297, 42.892684936524 16.670379638672, 42.910537719727 16.656646728515, 42.896804809571 16.618194580078, 42.927017211915 16.658020019531, 42.95997619629 16.658020019531, 42.962722778321 16.603088378906, 43.001174926758 16.658020019531, 43.008041381837 16.857147216797, 42.979202270508 17.052154541015, 42.984695434571". As discussed earlier, the first and last pairs are identical. I could write this out long-hand in Microdata or RDFa Lite, but the basic model is the key concern. I think we're getting somewhere, thanks for your help! Nearby in the Web, Wikipedia has pages for both island and city, http://en.wikipedia.org/wiki/Kor%C4%8Dula and http://en.wikipedia.org/wiki/Kor%C4%8Dula_(town) <http://en.wikipedia.org/wiki/Kor%C4%8Dula_%28town%29> It's also btw the alleged-birthplace-of http://en.wikipedia.org/wiki/Marco_Polo but let's get the basics working first :) cheers, Dan _______________________________________________ Geowanking mailing list Geowanking@geowanking.org http://geowanking.org/mailman/listinfo/geowanking_geowanking.org -- Sean Gillies
