				<title>anyone has attempted to make relations between places and islands? </title>
				<description><![CDATA[ I realize this is a tough one, but: 

has anyone attempted to create the relationship as to what places lay on (are contained in) a particular island? 
perhaps using other data in conjunction to geonames? 

Or if it can't be done, i'd like to know why.

				<description><![CDATA[ It has not yet been done as far as I know. With polygon information for islands it would be rather easy to achieve, but without this it is a lot of work. So I would start looking for island polygons.

				<description><![CDATA[ for those interested and for future reference: 

it can be done pretty realiably in conjunction with Yahoo Geoplanet. given that:  
1. island is a featurecode in Yahoo geoplanet. 
2. island returns children. 

so, given all islands in the geonames db, use: /places webservice: 

1. lookup islands by name and filter on type

i.e: http://where.yahooapis.com/v1/places$and(.q(texel),.type(island))?appid=YOUR_APPID_HERE
gives: Texel.  an island in the netherlands

2. (optinonal) disambiguate by lat/ long if necessary. 

You now have the woeid of the island. 

3. iteratively walk down the hierarchy-tree until entities of type Town are reached using webservice: 
/place/<woeid>/children

i.e: http://where.yahooapis.com/v1/place/12474877/children?appid=YOUR_APPID_HERE


Cheers,
Britske

				<description><![CDATA[ of course you have to map those woeid-towns back to geoname-ids, but since you have lat/ long pairs, name and country that can be done pretty realiably and efficiently. ]]></description>
