Re: How to express something is-located-at an org:Site

Virtual Locations are a problem because they get tied to Countries and only in Trade/Transport Applications do programmers remember that International Waters is a "Country".  The Ordinance Survey has it right, I think.  DCMI does not make a distinction between Spatial Thing and Spatial Object.

Hi Jakob,

I understand your use case and personally would not be adverse to adding
an aligned superproperty for org:hasSite.

The question is what one?

As you point out, org:Site is supposed to encompass non-physical sites.
This was to cater for organizations which use, for example, shared
virtual offices. Indeed I assume your my:digitallibrary is not a
physical location.

The trouble is that dct:Location is described as a "spatial region or
named place"; dbpedia:Place and http://schema.org/Place seem to be
definitely physical spatial locations. That seems to make them
unsuitable super classes for org:Site and presumably not suitable for
your digital library use case.

Can anyone with deeper understanding of DCT comment on whether this is
too narrow a view of dct:spatial/dct:Location - could a virtual office
or digital library be reasonably treated as a dct:Location?

Dave

P.P.S. Apologies for any email noise from a previous failed send
