Re: Linked Data Aspects of R2RML

Michael and all,

I have a question about reusable identifiers.

If I have my movie rental company relational database and I want to expose
it all as Linked Data. What should be the identifier for "Breakfast at
Tiffany's?"

http://dbpedia.org/resource/Breakfast_at_Tiffany%27s_%28film%29
http://data.linkedmdb.org/resource/film/71
okkam identifier for Breakfast at Tiffany's (if it exists)

or should it be a

http://myrentalstore.com/resource/film/123 owl:samesAs
http://dbpedia.org/resource/Breakfast_at_Tiffany%27s_%28film%29

Audrey Hepburn, can be considered a well known entity with URIs in dbpedia,
freebase, etc. We know that Audrey Hepburn acted in Breakfast at Tiffany's.
So should I have my own URI for the movie and reuse an identifier for Audrey
Hepburn?

I agree that we need to offer the possibility in the language to reuse the
identifiers, I'm just wondering what is the use case.
