Vocabulary interlinkage diagram
By Yves on Tuesday 7 October 2008, 11:00 - Permalink
The UMBEL people (Fred and Mike) just released a new interlinkage diagram. This time, it doesn't represent the different links amongst datasets made available within the Linking Open Data project, but rather a map of the links amongst vocabularies used on the data web.
The Music Ontology sits right between FOAF, FRBR and the Event ontology (although I would have added the Timeline ontology as well). There is also the Programmes Ontology, at the bottom (which is also interlinked with the Event ontology, btw).
This diagram really helps to see how the current web ontology
landscape
is structured, and I hope we can keep use it to keep track of the
evolution of web ontologies, a bit like what has been done for
the available datasets and interlinks.

Hi Yves!
About PO: I will check the version I have right now, but it is true that it is supposed to be linked. Theorically there should be a way since this graph is built automatically by a script. Some or there is a bug in the script (strange since other subclassof are working) or I didn't use the latest version (the one I used is a couple of months old). Will fix and republish :)
About the timeline ontology I will check this; but which ontology links to it (or it links to?)
Thanks!
Take care,
Fred
Hello Fred!
MO does - I am not sure if it actually "links" to it (e.g. subclassing etc.) or just mention timeline terms in the RDF though (I wonder... should this be counted as a link? Ultimately, yes, I'd think).
Cheers!

Hi Yves,
Thanks for the nice post.
Thanks for the pointing out the Programmes Ontology <--> Event oversight. That caused us to find a couple of similar ones with bibo and dcterms, too, with FOAF and Event. We will make those corrections in the next update.
As we said in the announcement, there are likely other omissions as well and we welcome input. It may likely require the ontology authors such as yourself to help discover all of the missing pieces, since we do not have all of the stuff indexed locally.
As for Timeline or Time, can you point us to where either link to any of the existing vocabularies on the chart? We'd like to include them in the next update, too, but would obviously prefer they not be "free floaters" on the chart.
Ultimately, of course, we hope this chart helps stimulate the providers of datasets to make still more class-level mappings, assuming they do so correctly!
Regards, Mike
