Dear all,

I asked myself a series of questions about the links between Wikidata and other knowledge/data bases, namely those of OCLC and DBpedia. For example:

- Why Wikidata has no property "Worldcat Identities" while the English edition of Wikipedia systematically mentions this identity (when it exists) in its section "Autorithy control"  ? 

- Why do VIAF links to all editions of Wikipedia, but not (simply) to Wikidata ?

- Why is there no link to DBpedia when the opposite is true ?

These questions may seem very different from each other, but they ultimately concern a common subject and are all very basic. I suspect they had to be discussed somewhere, maybe at the dawn of Wikidata. However, I find nothing in the archives of this Newsletter, nor in the discussions on Wikidata. 

Could someone point me to some documentation on these issues ? 

Cheers,

Ettore Rizza
