SIOC properties cardinality
Hi all,
I was thinking about adding cardinality restrictions to some of the
SIOC properties (if so, the ontology will use OWL properties instead
of RDFS one, but I don't think that's an issue).
It will allow to more precisely mention what we expect from SIOC data
(and also valid this).
The list has been added to OntologieIssues page of the wiki [1] and
here's a few one to discuss:
* account_of: min = 1; max = 1 .
If an account is shared by more that one foaf:Person, I think it's
better to use a foaf:Group as range since sioc:account_of has
foaf:Agent for range (not already in the specs, but seems it was
agreed on the list [2])
* avatar: max = 1 ?
A foaf:Person can have many foaf:depiction, but for a give user maybe
one avatar is enough ?
* content: min = max = 1
Only one content for a post (+ the encoded version)
* email: max=1 ?
Only on email per sioc:User ?
Is that needed ?
* email_sha1: same as email
* has_container: min = 1;
If max = 1, can we use sioc:sibling for same posts on other forums ?
* has_creator: no min, as we can have only foaf:maker; no max (i.e.
colaborative pages / wikis)
* has_host: min = 1; max ?
* id: max = 1
Must be unique, as the spec says
* ip_adress: max = 1
Should be unique for a given sioc:Post
* link: max = 1
Only one HTML page for a sioc:Post ?
* name: min = 1 (needed ?); max = 1 (only on name per sioc:User ?)
Best,
Alex.
