Re: RSP Data Model

Dear Emanuele,

I don’t quite follow the punctuation argument meaning that we can only have one graph at any given time point.
(Unfortunately I’m on the train home and cannot access the article that you linked.)

We still have the gain over the traditional streaming RDF model in that all triples conforming to a given observation will be contained in the graph. So why does having more than one graph at a given time point cause a problem?
(Sorry if I am missing something obvious)

Best regards,

Alasdair

Dear Alasdair, and all

thanks for the report. I would like to point out that the sentence “There can be multiple graphs with the same timestamp” is, in my opinion, a bad choice. It will prevent graphs to be interpreted as a form of punctuation [1] and this was one of the most important gain of the version of RSP Data Model discussed in Berlin (i.e., graphs with strictly increasing timestamps). The lack of punctuation is a problem of the “traditional" timestamped triples data model where contemporary triples must be admitted.

Best regards,

Emanuele

Hi All,

During the ESWC RSP Workshop we had a breakout group focus on defining the RSP data model. I was charged with the action of updating the semantics document with the agreed model.

You can find the updated data model at

Best regards,
