Hi Søren

Interesting stuff indeed. Re. the "sites" did you think about linking to
geographical entities in the LOD cloud (Geonames, freebase, DBpedia,
whatever).

For example in the description of http://eunis.eea.europa.eu/sites/AT930056

Using the geolocation elements
<longitude>15.833333333</longitude>
<latitude>46.750000000</latitude>

You can query the geonames webservices for the nearby populated place
http://ws.geonames.org/findNearbyPlaceName?lat=46.750&lng=15.833&type=rdf

Yielding the description of http://sws.geonames.org/2762642/  (Unterspitz,
Austria)

Hence you could easily add to your description the following triple

<http://eunis.eea.europa.eu/sites/AT930056>  foaf:based_near  <
http://sws.geonames.org/2762642/>

Best

Bernard

> 2.       sameSpecies, which links from a EUNIS accepted name to an accepted

>
> We also have negative matches: notSameSynonym and notSameSpecies. These are

> Practical examples:
>
> Danaus plexippus (Monarch butterfly)
> http://eunis.eea.europa.eu/species/90910
> Canis lupus (Gray wolf) http://eunis.eea.europa.eu/species/90910
> The Polish site Lasy Janowskie http://eunis.eea.europa.eu/species/90910
