An interesting side debate is whether we want more Linked Data, or more RDF? Surely the latter!

There are actually multiple standards that came about when the semantic web was coming into being. RDF has just been used more and has been taught more. However, it is simply not flexible enough for some types of data sets. Firmly linking RDF as intrinsicly required for Linked Data, therefor, seems like a dangerous game that furthers nothing and may very well leave out the linking of some open data that would be better served by other semantic technologies.

Lorna,

Let’s make one more pair of distinctions very clear:

1. linked data does not imply open data
2. open data does not imply linked data
3. linked data does not imply RDF data
4. RDF data does not imply linked data

(4) may seem a bit unintuitive, but it is possible to have a set of RDF triples where none of the objects are URIs, ie they are all literals. This would NOT be linked data in my book. Or one could have a set of RDF triples using a set of proprietary URNs instead of HTTP URLs, and again this would not be linked data in my book.

@Kingsley thank, I rather like the distinction you’ve drawn here. @Nick interesting contribution to an ongoing debate.

FWIW personally I agree that RDF is not a prerequisite for Linked Data and that it is important to retain the distinction between Linked Data and Open Data, because as many other commentators have already pointed out linked data need not necessarily be open and open data need not necessarily be linked.

My take on the linked data debate: http://blogs.gartner.com/nick_gall/2010/07/21/tim-berners-lee-doesnt-seem-to-think-linked-data-requires-rdf/ (since trackback didn’t seem to work).

Question: What do you call LInked Data that isn’t inextricably bound to RDF?

Answer: HTTP based Linked Data.

Question: What do call Linked Data that is inextricably bound to RDF?

Answer: RDF based Linked Data.

The original Linked Data meme by TimBL made no specific reference to RDF or SPARQL. Said technologies are purely implementation details re. Linked Data.

For more insight please read my Data 3.0 Manifesto [1] which is basically about decoupling RDF and Linked Data.
