Hi Luc,

 

I would recommend dropping the 'has' from 'hasParticipant' (silent 'has'
rule on noun predicates), or, optionally, finding an appropriate gerund
phrase with a noun suffix, perhaps 'Party' in this case. The predicate would
then be 'participatingParty'. So in answer to your question, the predicate
names become tense-less verb or gerund phrases.  Specification of tense can
be done either with reification or, in the case of, RDF-based models, use of
rdf:Statement.

 

Below is a diagram generated by TopBraidComposer of, what I believe to be a
current Provenance Ontology model )from
http://dvcs.w3.org/hg/prov/file/738e9b4d8520/ontology/ProvenanceOntology.owl
):

 



 

The Turtle file is attached (I need to consult others on where to put such
files on the WG site). I transformed the OWL original using SPIN rules so I
can repeat this process in the future.

Hi Ralph,
Don't you end up with a mix of relation names:
 uses, derivedFrom and hasParticipant ?

My preference is for uniformity. If we go for a verbal form for some, we
should go for all;
otherwise for none.

Propose that 'is' be dropped from all predicates that have a suffix. Two
reasons - parsimony and connotations (in fact denotations) about tense are
removed.

 

            Example: 'isDerivedFrom' becomes  'derivedFrom'.

 

Also advocate that all predicates begin with a lowercase letter.

Hi Daniel and Simon,

In the conceptual model (up to section 5), all relations use present tense,
uses, isDerivedFrom, isComplementOf, isGeneratedBy, ...

I agree with Daniel, we need consistency in the conceptual model and formal
model.

I agree with Simon, it's nice to point back into the past.

Luc

PS. I took as an action to poll about the use of tense.

+1 for "used", for the reasons you give.
 
-1 for "isUsedBy". All other relations in the model link effect/later
occurrence to cause/earlier occurrence, so "isUsedBy" would be
inconsistent. This means that provenance graphs would not consistently
point back into the past of the thing we're seeing the provenance of,
and would be confusing to iteratively navigate.
 
Thanks,
Simon

Raised by: Daniel Garijo
On product: Formal Model
 
Since all the other properties are using the past tense, we should be
consistens and rename uses to "used" or "isUsedBy" flipping the domain and
range
