Re: PCA RDL Verification

The following SPARQL query is looking in PCA RDL for RDS-entities which have R-numbers assigned via rdsWipEquivalent predicate but have no other data about them at the endpoint (no type, no label, nothing). PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> PREFIX RDL: <http://posccaesar.org...

Re: Domain-specific instances of ClassOfIndirectProperty in

In the HEED project we encountered problems in finding the proper ClassOfIndirectProperty for the domain of Pumps. The project participants work from a kind of RDL defined by the Hydraulic Institute and by NIST. These are good definitions, meaningful for that domain, that, however, not always fit i...

Re: Lists in Template Roles?? Options/Objections/Solutions?

Hi Andrew, From my talks to Duhwan Mun I guess that it would be better to use EnumeratedSetOfClass. See http://15926.org/templatespecs/CL-SHAPE-06.xml Regards, Hans Well we need an ordered list for our purposes so my thoughts were to use MultidimensionalObjects From Part 2 we see that its defined a...

Re: Structures for the publication of TIPs

This parameter will resolve the problem, but I can not see it in the model. More then that, such third role is completely unnecessary. In templates existential quantifier (or Scolem variable) is used to hide exactly this type of unnecessary data items. Why do we return them into patterns? In this s...

Re: Nullifying Values in Part7/8

Does this have to be individual? we talked in the Geometry SIG about the same issues and those aren't Individuals. How about StatusOfPropertyOfThing? Sounds reasonable to me I see the business need for this has been reinforced by the gaps list document produced by the Dexpi group who have this expl...

Re: Nullifying Values in Part7/8

Agreed on the "Withdrawn" and "Canceled". We will certainly need temporal parts for properies at some point and perhaps this is a good place to start that discussion. As yet there do not appear to be any templates for that. The initial set contains templates with temporal roles for classes and indi...
