We recently discussed the current CPSV-AP draft internally and were wondering on how to use the Public Service class' spatial/temporal property in practice.
Well, there seem to be predefined URI sets (http://publications.europa.eu/resource/authority/atu/) for expressing spatial coverage, but how about temporal boundings - is there a controlled vocabulary as well?
And what if one intends to define both properties for a public service - spatial coverage as well as temporal coverage? Just use one property for spatial and an additional one for temporal data? Shouldn't those properties be separated in a way that each serves a specific purpose? Why is the nature of the property be a mixed one?
I would be glad if somebody could clarify on that - thank you!

Thanks Dominik,
I must apologise that the documentation wasn't clear. There are two separate properties, spatial and temporal. They're described together as they are closely related. I have made the wording (and presentation) clearer:
A common usage of the spatial property will be to define the Administrative Territorial Unit(s) – typically a country or region – in which a Public Service is available. The Publications Office of the European Union offers a URI set[1] that is suitable for this purpose, e.g. Malta is identified by http://publications.europa.eu/resource/authority/atu/MLT,
West Flanders by http://publications.europa.eu/resource/authority/atu/BEL_PR_WVL and so on.
Section 3.12 describes the Period of Time class that should be linked from a Public Service using the temporal property.

There are other problems with the temporal property so it was decided during the meeting on 18/11 to remove it altogether (spatial is still there though).
