 Hi all,
 
 is there a preferred way to represent the relation between posts in 
 different Social Sites? For example, it is now pretty common to post to 
 Twitter, and this post becomes a post in my wall in Facebook. It would be 
 nice to represent the relation between these two posts.
 I don't think this can be represented directly using SIOC, for instance.
 
 dc:source ? 
 
 I can't really believe that SIOC does not have this feature.
 
 Well, I could not find it, hence my question. Hopefully the SIOC Gurus may 
 have an answer...
 
 As Stuart pointed out, we want to capture the fact that it is the same post, 
 but within different contexts. In many cases, they will be generated 
 automatically...

As Nathan, suggested, the sioc:sibling has been designed for that

http://rdfs.org/sioc/spec/#term_sibling

An Item may have a sibling or a twin that exists in a different Container, but 
the siblings may differ in some small way (for example, language, category, 
etc.). The sibling of this Item should be self-describing (that is, it should 
contain all available information).

Won't it be enough for your needs ? 

Best,

Alex.

Interesting. We tried to keep the ontology reasonably neutral, that's
why, for example, there is no notion of a Government or Corporation.

Could you say a little more about the specific Western  Westminster
assumptions that you feel are built into it?

We do have the notion of a Head role and corresponding headOf
relation (because it is such a common notion and part of our competency
questions) but there are no cardinality constraints and no requirement
that any specific organizational structure support that role.

 What would be great would be to see a handful of different
 organisations (or portions of them) from different traditions
 modelled. Maybe:
 * The tripartite system at the top of US government, which seems
 pretty complex to me, with former Presidents apparently retaining some
 control after they leave office

Control is a different issue from organizational structure. This
ontology is not designed to support reasoning about authority and
governance models. There are Enterprise Ontologies that explicitly model
authority, accountability and empowerment flows and it would be possible
to create a generic one which bolted alongside org but org is not such a
beast :)

In terms of web architecture both options are the same. But the first  
one has several “soft” advantages:


- more idiomatic and hence easier to remember and use
- more compatible with the Hierarchical URIs pattern [1]

Re: Organization ontology

2010-06-02 Thread Kendall Clark
To give some different perspective, I don't believe that any of those
issues w/r/t to other governance models impinge on the quality or
utility of this organization ontology whatever. Does it accurately
depict every possible scenario? Not at all. Is it adequate for the use
cases and requirements it was set out to achieve? It certainly appears
that way.

Further, governance is -- as Dave points out -- in some ways
orthogonal to organizational structure (so, in some sense this is
*not* true, in that some org structures prohibit or inhibit some
control models, and vice versa, but that only matters here if it does,
and I claim that it doesn't).

This is -- as I said on Twitter last week -- outstanding work and we
will be adopting  adapting it in our work at NASA and other fed govt
customers.

Cheers,
Kendall Clark
