Re: Versioning info for schema.org?

Hi Joseph

In the framework of the Linked Open Vocabularies project we have started to
tackle this issue and are storing on OKFN servers a backup of vocabulary
versions, either explicitly declared by vocabulary publishers, or
implicitly entailed from changes detected by our "LOV-Bot" which is
scanning daily all stored vocabularies and compares the current on-line
version with the last version in store (on a triple-by-triple basis).
For schema.org we have just started and have not a long history [1], but
for older vocabularies we have an interesting timeline that you might be
happy to use, see e.g., [2] for the geonames ontology. The timeline is at
the bottom of the page.
Versions and history are stored in LOV RDF store using a FRBR
representation, explained shortly at [3]. A proper paper about all this is
planned with Pierre-Yves Vandenbussche in cc, we will keep you informed.

Best

Bernard
