Transforming SHOE to RDF

First, we define some RDF terms (classes, properties) corresponding to terms from the shoe spec[Shoe]. This is maintained as HTML and available as RDF via a transformation.

Note that these are only the terms from Shoe markup and the shoe spec that are not shoe categories/relations/types themselves. The RDF form of things like .STRING is taken from the Shoe ontology, via shoe-swell.xsl, an XSLT transformation. For example, the shoe base ontology in RDF is derived by machine from the shoe base ontology.

Properties

• id: Ontology -> Literal
• version: Ontology -> Literal
• backward-compatible-with:

  @@subsumes... hmm.

• declarators
• use-ontology

  @@TODO relate to assertion by reference

• isa

  @subproperty of rdfs:subClassOf (odd; usually subclass is called "ako" in systems that use "isa")

• short : rdf:Resource -> rdf:Literal

  @@subProperty of rdfs:label

Source Code

• shoe-swell.xsl convert SHOE to swell, Semantic WEb Logic Language, i.e. RDF with (eventually) some logic stuff (inference, lists) layered on top
• shoe-ns.xsl namespace-qualify shoe markup
• tidy configuration for shoe markup
• Makefile, which documents dependencies on XSLT (XT, Java), tidy, etc.
• @@tar/zip

Examples

• SHOE base ontology in XML with namespaces derived from shoe base
• RDF output from xhtmlized version of PLUS: Personnel page
• general.rdf, from the Shoe general ontology
