hi Greg, all, re actions: [[ # libby/danbri/nick/steve: to work on an account of the data we'd want. it may not need a new schema at all ]] (action from http://esw.w3.org/topic/WWW2004) An 'account of the data we'd want' is here http://esw.w3.org/topic/ImageDescriptionRdfExamples (thanks also to Jennifer Golbeck) There are some example files, e.g: http://swordfish.rdfweb.org/discovery/2004/01/www2004/path-eg.rdf and I have used CWM to generate a schema: http://swordfish.rdfweb.org/discovery/2004/01/www2004/schema-eg.rdf using these sample data files: kanzaki-eg.rdf (thanks Masahide) long-eg.rdf path-eg.rdf Couple of design decisions: (1)In the examples and generated schema I've used Jim Ley's classes and properties to describe parts of images; however it's clear that this needs some more discussion, and indeed one of the purposes of the proposed new list is to work this out: http://esw.w3.org/topic/ImageDescriptionList - I propose a specific IRC chat about this topic on another day (2)I have reused classes and properties from existing vocabs rather than create a new one. Jennifer Golbeck has taken a different tack: http://www.mindswap.org/~glapizco/technical.owl There is a clear difference in philosophy here between people who are used to working with strong OWL (and perhaps RDFS) tools and those without; from an OWL point of view in particular: [[ <nmg> libby: in the OWL worldview, the axioms which form the links between two existing ontologies are themselves another ontology which extends both of the ontologies it links ]] and owl:equivalentClass between classes means that they are the same class, so from an owl point of view there is simply no difference between using owl:equivalentClass and creating a new ontology, and reusing existing terms. For tools that don't have particularly good RDFS or OWL support there is a big difference however, dramatically reducing interop and the usefulness of the dataset (imho). In addition, due to current processing capabilities it is generally faster to mix vocabs directly rather than using equivalencies: [[ <DanCon> I think equivalencies are for when you discover that they're the same after-the-fact; it's antisocial to make aliases. 15:19:22 <DanCon> ... to make aliases on purpose, that is. ]] http://www.ilrt.bris.ac.uk/discovery/chatlogs/rdfig/2004-01-07#T15-18-49 I think this is an important issue (both for the image ontology and the conference ontology), and so I'd like to see this on this or another agenda so a decision can be made (we've had discussions but no decision as yet: http://www.ilrt.bris.ac.uk/discovery/chatlogs/rdfig/2004-01-06#T15-39-28) cheers, Libby On Tue, 13 Jan 2004, Greg Elin wrote: > (Apologies...sent last night, but from the wrong address!) > > Quicky Agenda for Jan 13 IRC 16:00 GMT > Host: irc.freenode.net Channel: rdfig > > Please check links before meeting if at all possible! > > "Getting things ready to be public" > > I.
