Here's a nice practical example: the Dublin Core Metadata Initiative.

http://purl.org/dc/aboutdcmi ->
http://dublincore.org/DCMI.rdf

<rdf:RDF

There was a little discussion on this point: when was the Dublin Core
created as an organization? It began in 1995 but as an informal
internet-mediated community. In recent years this has increasingly
solidified until now there is a legal entity;
http://dublincore.org/about-us/  "The Dublin Core Metadata Initiative
(DCMI) is an open organization, incorporated in Singapore as a public,
not-for-profit Company limited by Guarantee (registration number
200823602C), engaged in the development of interoperable metadata
standards that support a broad range of purposes and business models."

RDF doesn't natively handle the representation of changes over time.
In some contexts we'll want to talk as if there is a single thing that
existed since 1995. In some other contexts we'll want to be precise,
and talk of the legal entity in Singapore. RDF has the basics to allow
this kind of separation and folding together of perspectives, but in
everyday practice we don't yet do it very well, to be honest. I'd be
interested to see proposals for refining the Dublin Core's
self-description to include a more detailed picture using the Org:
vocab...

cheers,

Dan
