Re: My slides for TPAC

Hi Ora,

that’s a nice and concise introduction! Nonetheless I have a few remarks and requests ;-)


Re slide #4, Some use cases

One might say that the different use cases represent different degrees of orthogonality between statement and annotation. Provenance or marginalia are usually considered very orthogonal, i.e. not related to the fact itself (although e.g. in court provenance might be tightly coupled to creativility and therefore truthfulness). Qualifying statements and the kinds of annotations I know from LPG examples are very much concerned with the content of the statement itself, adding detail and context. 
One might write:

Some use cases

differing in how they interpret the connection between statement and annotation,
from largely orthogonal to practically integral

Provenance (the prototypical RDF example)
Marginalia
Modalities 
Qualification (often seen in LPG examples) 

Also: bringing RDF closer to LPGs (aka “alignment")


Re slide #6, Semantics proposal:

"We have agreed on a minimal baseline" - I only agreed to it being a good basis to compare further work against ;-) 

"We have two alternate, extended baselines we are still discussing" - if that includes also the "Extending the baseline with "asserted" stuff" then I’m in principal satisfied. But a tad more detail might be justified?


Re slide #7, Syntax proposal:

The alternatve syntaxes are named "occurrence syntax" and "annotation syntax". The main difference IMO is that the first one doesn't assume the the reification is actually stated whereas the second does (and indeed states it). Therefore I’d propose to call the first "unasserted syntax" and keep the second one as "annotation syntax".

Of course there is a connection to my argument about the need for another property like rdfs:states and one might consider me biased, but the syntaxes motivate that need, not the other way round, so I think my proposal is warranted.


Best,
Thomas
