Modeling the relation between a resource and the site it belongs to
Stephane Corlosquet
I think there an aspect which is quite important that we've missed so far in the implementation of RDF in Drupal 7, which is modeling the site a resource belongs to. Again, I'd like to keep it simple and limit this to one triple such as:
<http://mysite.com/node/12> sioc:has_container <http://mysite.com/>
or
<http://mysite.com/node/12> dc:isPartOf <http://mysite.com/>
I think this would enable useful queries such as find all resources hosted on a given site... Looking for something generic: some sites will be hosting communities where SIOC applies, but some others will be boutique sites with fairly stable content and not community driven at all. Does dc:isPartOf apply well here?
Steph.

I haven't seen any response to this question.
Maybe because it's asked in the context of Drupal ? But I think it's a
general question in any case, for which I'm also interested.
Maybe one can assume that resource URIs convey the semantics of their
belonging, but I'm not so much satisfied.
My use case would be to express links between users of a platform and
their accounts in different tools that are assembled in this platform.
For instance, foaf:holdsAccount help make a link between several
accounts (sioc:User) of a foaf:Person, but I can't see an obvious way
to state which of these sioc:User is linked to which sioc:Container
(different collaboration spaces like a Wiki, a Forum, etc.).
Looking forward to reading more answers on that subject.
Best regards,
Nathan

all depends on the nature of the link between the sioc:User and the
sioc:Container I guess? Generally using sioc:Role handles most
use-cases; and dct:creator/modifier etc handle other types of
relationship; and further still you can infer more from the
relationships between a sioc:User and the sioc:Item(s) within the container.
What's your specific need / the relationship you need to describe?

It's quite simple : in a wiki I may be using an account named
"OlivierBerger" and in a forum, I may be recognized as "oberger"
so :
<http://somewhere/people/olivier/#me>
a foaf:Person ;
foaf:holdsAccount <http://somewhere/wiki/awiki/users/OlivierBerger>;
foaf:holdsAccount <http://somewhere/forum/aforum/users/oberger>.
and :
<http://somewhere/wiki/awiki/apage>
dc:creator <http://somewhere/wiki/awiki/users/OlivierBerger>;
sioc:has_container <http://somewhere/wiki/awiki>.
or :
<http://somewhere/forum/aforum/messages/1234>
dc:creator <http://somewhere/forum/aforum/users/oberger>.
sioc:has_container <http://somewhere/forum/aforum>
Now, is there a way to say :
<http://somewhere/wiki/awiki/users/OlivierBerger>
a sioc:User ;
whatever:is_an_account_in <http://somewhere/wiki/awiki>.
or
<http://somewhere/forum/aforum/users/oberger>
a sioc:User ;
whatever:is_an_account_in <http://somewhere/forum/aforum>. ?
And no matter which role my accounts may have (moderator, editor, admin
or whatever) ... and I believe semantically speaking an account in a
collaboration space may not be seen as a role.
I hope it makes it clearer question now ;)
Thanks in advance.

FOAF's preferred name for these relationships is now foaf:account -
see http://xmlns.com/foaf/spec/#term_account (the older variant
foaf:holdsAccount is still included). One of the motivations
justifying this minor disruption btw was that it looks a lot more
presentable in RDFa links...
cheers,
Dan

other than inferring it in some way; I guess you could
<http://somewhere/forum/aforum> a sioc:Forum, sioc:Community;
sioc:has_usergroup <http://somewhere/forum/aforum#usergroup> .
<http://somewhere/forum/aforum#usergroup> a sioc:UserGroup ;
sioc:has_member <http://somewhere/forum/aforum/users/oberger> .
?

OK, thanks for the hint... but... any clue on my question ? ;)

That makes sense, but I would have expected a more direct link maybe...
I can be a "lone" poster to a forum and not really be considering myself
as a member of any group (i.e. sub-community, or specially granted of
some group-based roles...).
<http://somewhere/forum/aforum/users/oberger>
sio:member_of [
a sioc:UserGroup;
sioc:usergroup_of <http://somewhere/forum/aforum> ].
ok... hmmm an unspecified group of which I'm a member on that
platform... I'd prefer a kind of shortcut ;)
Thanks a lot.

It's probably the closest to what I was looking for, even though the
range is a foaf:Document and not a sioc:Space.
Reusing my example and trying to be formal, it would give :
<http://somewhere/forum/aforum/users/oberger>
a sioc:User, foaf:OnlineAccount;
foaf:accountServiceHomepage [
a foaf:Document;
is foaf:homepage of <http://somewhere/forum/aforum> ].
And eventually, we may use the shortcut of :
<http://somewhere/forum/aforum/users/oberger>
a sioc:User, foaf:OnlineAccount;
foaf:accountServiceHomepage <http://somewhere/forum/aforum>.
if we assume the sioc:Service and its homepage foaf:Document are the
same ?
Thanks in advance.
