Re: [Crm-sig] URI to refer to CIDOC-CRM and FRBRoo namespace(s) and concepts?

[Regine Stein]

Hi,

This requires indeed some official fixing since composing the URI from
    http://www.cidoc-crm.org/crm-concepts/ plus entity number
    e.g. http://www.cidoc-crm.org/crm-concepts/E22

was the advice given by ICS-FORTH at the time of delivering LIDO v1.0.
(and the LIDO spec follows it btw consistently, differences below seem 
to be due to word-wraps)

Please let us know if these are not valid anymore (which I wouldn't 
consider best practice..)

Best,
Regine

Hi Michael!

The LIDO spec says: "CIDOC-CRM concept definitions are given at
http://www.cidoccrm.org/crm-concepts/ Data values in the sub-element term
may often
be: Man-Made Object (with conceptID
"http://www.cidoc-crm.org/crm-concepts/E22";),
Man-Made Feature (http://www.cidoc-rm.org/crmconcepts/E25), Collection
(http://www.cidoc-crm.org/crmconcepts/E78)."
I think this is bad advice on several fronts:
- I see 4 URLs above, and all 4 are different ;-)
- It doesn't refer to the official release URI (see below)
- I think that using numbers only, without the English labels, is calling
for trouble and errors

The page http://www.cidoc-crm.org/official_release_cidoc.html lists some
oficial URIs.
I would use this one: http://www.cidoc-crm.org/rdfs/cidoc-crm-english-label
.
This URL resolves (following linked data principles) and redirects to the
current version:
http://www.cidoc-crm.org/rdfs/5.0.4/cidoc-crm-english-label

Martin, I'd suggest several fixes:
1. Please make the official URIs into links:
  http://www.cidoc-crm.org/rdfs/cidoc-crm-english-label and
http://www.cidoc-crm.org/rdfs/cidoc-crm .
2. Please fix this link later in the page to use the same URI for the
current version:
   http://www.cidoc-crm.org/rdfs/cidoc_crm_v5.0.4_english_label.rdfs
3. Fix the MIME type returned by the server
-- currently it is:
curl --head http://www.cidoc-crm.org/rdfs/5.0.4/cidoc-crm-english-label
Content-Type: text/xml
-- should be:
http://www.w3.org/TR/2004/REC-rdf-syntax-grammar-20040210/#section-MIME-Type
Content-Type: application/rdf+xml

Can I just add on the relevant FRBRoo term ID (e.g. F26 for movies) to the
URI prefix
for CRM? E.g. yielding "http://www.cidoccrm.org/crm-concepts/F26";?
You shouldn't, as these are separate ontologies

2. Is there a URI to denote CIDOC-CRM or FRBRoo itself as the "source" of
a
concept? I.e. the URI for the concept scheme?
Do you mean SKOS "concept scheme"?

Cheers! Vladimir
