Yes, if we have different URIs for each version of E5 Event, then this will complicate matters during implementation in local systems. If one wants to work out the difference in reasoning rules across the versions then they would need to refer to the whole document not each individual class.

Dear all, This very interesting conversation was up to now focusing on CRMbase. But what about the extensions family ? Often pointing from one extension to antoher ? One major point for having machine actionable, consistent ontologies is to have a mechanism to point to the versions of each

My underlying assumption would be that the default thing served up would be html, but you could reach the other representation consistently through adding an appropriate ending or whatever would be most suitable... but that people looking at the html should have a shiny red button type clue

Hi Robert, Yes it is really quite nice actually. A hidden gem as it were. About why it doesn't exist past 6.2.2, it's a bit odd. I would have said it is because it is only made for official release versions (like 6.2.1) but I see that it has been made for other non official versions. Perhaps it

For the appearance/presentation of the whole ontology, it is an html representation of the main document that we create. This seems fine. Would it be useful to be able to provide links explicitly at the top of this document to click over to encodings? This way somehow we can better consolidate

I agree with Detlev's proposal. Also, I believe that versions should not be included in the class URIs. These are not normally used to retrieve reasoning rules but only to identify classes, right? Resolving the class URI should return all versions of the class. All the best, Thanasis On

Dear all, I have a question about CIDOC CRM URI management. The last published version of CRMbase is 6.2.1. If I take the RDF serialization, I find this base URI: http://www.cidoc-crm.org/cidoc-crm/ If I sent this URI in the web: http://www.cidoc-crm.org/cidoc-crm/E92_Spacetime_Volume I
