Re: Proposal of definition for timestamped graph

Hi Tara,

Will you be able to make the call today? If you are there will you be willing to talk about the new proposed data model?

Best regards,

Alasdair

I have created a pull request for the proposal for a revised definition,
and included some examples. The previous definition is still visible from:

https://github.com/streamreasoning/RSP-QL/blob/master/Semantics.md


while the new definition, plus some possible serializations, can be seen
in my fork

https://github.com/greenTara/RSP-QL/blob/master/Semantics.md


There is a slight merge conflict, but I think it is not too bad.
Apparently I did not pull the latest commit from Alasdair. But I am
requesting that the pull NOT be merged yet so we can easily compare the
previous definition to the new proposal.

I still have some concerns about the case where the named graph is not
included in the timestamped graph, i.e. only the IRI that is its name is
transmitted. Unless the timestamped graph is interpreted in some
"context" where there is some set of known named graphs, this
formulation seems to leave the semantics of a timestamped graph at the
mercy of the state of the internet (for dereferencing the named graph).
