Hi Antoine,
Many thanks.
Actually, that prompts me to ask a question about LOV.
I see that LOV says the AKT ontology voaf:reliesOn dcterms (with a very big circle).
This puzzled me because I did not think there was any connection between AKT and DC, so I drilled in.
I found, as far as I can tell, it is because the AKT vocabulary itself (at http://www.aktors.org/ontology/portal ) uses dct:creator, and documents that use the AKT vocab use dc:creator, dc:title, etc., about the documents and content itself.
This was not my intuitional reading of voaf:reliesOn - was it intended?
And if so, is it widespread in LOV?
(I realise this is probably a hard problem in general!)

It helped us to make the datasets from our community more visible to our community, without making it a hard pre-requisite to adhere to other communities' requirements.

>>> I guess that it was with the LOD *cloud* that you had issues. It looks a bit severe, but I think I understand the motivations: if the cloud admitted isolated nodes, it would have many of them, and that would look weird... But of course that does not make your contribution less interesting. On the contrary, the BL work has incredible potential for our domain!

We can now run single federated queries based on semantic alignment without the need to insert specific linking triples. When we applied to advertise our site on the LOD cloud we were turned down because we hadnít inserted specific links to other data sources. I realise that I could just stuff in a few links to Dbpedia to get accepted - but given that we can harmonise data to a very high degree with another open CRM RDF data source perhaps we should still be allowed formal acceptance to the open data community.
