Re: ISA Core Location Vocabulary

Hello,

Thank you for the notification. I was aware of the vocabulary, but it is 
good to  know that it is now out of the hands of the ISA programme and 
in our custody.

What I think is particularly interesting about this vocabulary is that 
its goal is to provide interoperability with INSPIRE. Does this mean the 
JRC and/or INSPIRE are seriously looking into using Linked Data as an 
alternative to ISO191xx? That would be thrilling! Have there already 
been attempts to recode INSPIRE themes as RDF vocabularies?

I recognize the terms from the INSPIRE themes, but I also notice that 
semantic interoperability is not complete. Take for example the 
geographical name. In INSPIRE it is a complex class, but although its 
data type is not defined in the vocabulary, it seems that the concept is 
reduced to a single text string.

A completely different thing: I see that the Location Core Vocabulary 
does not define a new way of encoding geometry, but rather permits the 
encoding specified in GeoSPARQL and Basic Geo. Was NeoGeo ever 
considered too? One consideration may be that the world at large will 
not be helped by having many different encodings for geometry. I think I 
would prefer just an encoding of WKT, but without including the (URI of) 
the coordinate reference system (CRS). I believe the SRS should be a 
separate entity, to be applicable to a geometry, to a collection of 
geometries, or to a dataset.

Regards,
Frans
