Subject: RE: [plcs-dex] OWL and Reference data
Hi Mats Some comments below
Regards ------------------------------------------- -----Original Message-----
Hi all, I'd like to restart a discussion about reference data which if possible should result in a meeting session in Valencia (yes, I'm going there) dedicated to reference data. [RBN>] I agree. Unfortunately, I will not be there. A high priority is to complete this initial set of PLCS reference data. This will involve taking all the modellers reference data from the individual modellers files, e.g. dexlib/data/refdata/plcs_owl/plcs-rdl-lgm.owl and moving it to: dexlib/data/refdata/plcs_owl/plcs-proposed.owl The main reason for bringing this topic up again is the need at FMV and the Swedish Defence to create/refresh a dictionary describing military and other common concepts. I've managed to make a number of the largest current projects interested in using OWL as the basic representation of the concepts/terms instead of creating an (e.g. Access based) application or using a simple (Word) document. The presentation to users would be in HTML created by XSL from the OWL-file (just like DEXlib or STEPmod). I believe you all can see some of the benefits this could lead to for us. [RBN>] There is already XSL to present the OWL files to the users. See: dexlib/data/refdata/plcs_owl/sys/class_exp.xml Do you have any suggestion as to how this presentation should
be improved? Therefore,
I'd like to hear your comments on the following issues: <owl:Class
rdf:ID="plcs00001"> [RBN>] I agree – that is what ID is used for. Label
should be used to provide alternative names, maybe in different laguages. To
quote from: ---------------------------------------
I
guess these should be included; … and probably a few others describing version, status (proposed, defined, obsolete..) a.s.o. [RBN>] I agree. When displaying the OWL classes, the XSL
already flags an error if the following are not filled in: ---------------------------------------
There is no (as far as I've seen) implemented functionality in Protegé for descriptions in multiple languages. But it might be possible to use the rdfs:comment tag with an xml:lang attribute?! Is this allowed in OWL? Can there be multible rdfs:comment tags according to the schema? In that case a possible solution is this; <rdfs:comment
rdf:datatype="http://www.w3.org/2001/XMLSchema#string"
xml:lang="en"> [RBN>] Yes, this is the correct approach, and yes you can already do this. Just add an rdfs:comment as another annotation property, selecting the language. Admittedly, Swedish does not feature as a language on the pull down menu- I am sure that this can be fixed. ---------------------------------------
[RBN>] OWL is represented as RDF and there is no guarantee
as to how that RDF is output. <owl:Class rdf:ID="Name"/> Sometimes you get a reference to the class defined first, in which case you get <owl:Class rdf:about="#Date_planned"/> IN other words, the OWL tools do not necessarily produce RDF
is a nicely ordered fashin. This makes writing any XSL against this a little more
complex. ---------------------------------------
[RBN>] Yes, you can add other annotation properties. I think that we should define a standard set that we want and document what they are though, rather than allowing people to add their own.
Looking forward to hear your comments/suggestions/questions…, and to see you in Valencia! Regards,
