My modified, extended and more generalized version of Danbri‘s SpecGen version 5. My SpecGen version 6 is able to generate a XHTML+RDFa ontology specification with common concepts and properties based on OWL, RDFS and RDF, and parse these statements into a template of the ontology documentation.

SpecGen v6

About

This is an experimental new codebase for specgen tools based on danbri's specgen5 version, which was heavily updated by Bo Ferri in summer 2010.

Features (incl. modifications + extensions):

  • multiple property and class types
  • muttiple restrictions modelling
  • rdfs:label, rdfs:comment
  • classes and properties from other namespaces
  • inverse properties (explicit and anonymous)
  • sub properties
  • union ranges and domains (appear only in the property descriptions, not on the class descriptions)
  • equivalent properties
  • simple individuals as optional feature

Dependencies

It depends utterly upon

(at least I had to install these packages additionally ;) )

If you're lucky, typing this is enough:

easy_install rdflib

and if you have problems there, update easy_install etc with:

easy_install -U setuptools

Purpose

Inputs: RDF, HTML and OWL description(s) of an RDF vocabulary
Output: an XHTML+RDFa specification designed for human users

Example

specgen6.py --indir=onto/olo/ --ns=http://purl.org/ontology/olo/core#  --prefix=olo --ontofile=orderedlistontology.owl --outdir=spec/olo/ --templatedir=onto/olo/ --outfile=orderedlistontology.html
  • the template of this example can also be found in the folder: onto/olo
  • the output of this example can also be found in the folder: spec/olo

See libvocab.py and specgen6.py for details.

Status

  • we load up and interpret the core RDFS/OWL
  • we populate Vocab, Term (Class, Property or Individual) instances
  • able to generate a XHTML/RDFa ontology specification with common concepts and properties from OWL, RDFS, RDF

Known Forks

  • WebID fork (note this link is only a reference to a specific revision of that fork; to ensure that you'll utilise the most recent one, go to summary and walk that path to the specgen directory again from the most recent revision ;) )

TODO

  • enable more OWL features, especially an automated construction of owl:Ontology (currently this must be done manually in the template)
  • enable more support for other namespaces (super classes and super properties from other namespaces already possible)
  • restructure the code !!!
  • write a cool parser for the "\n"'s and "\t"'s etc. in the parsed comments (e.g. "\n" to <br\/> ...)

Known Issues

  1. librdf doesn't seem to like abbreviations in FILTER clauses.
    • this worked:
      q= 'SELECT ?x ?l ?c ?type WHERE { ?x rdfs:label ?l . ?x rdfs:comment ?c . ?x a ?type .  FILTER (?type = )  } '
    • while this failed:
      q= 'PREFIX owl:  SELECT ?x ?l ?c ?type WHERE { ?x rdfs:label ?l . ?x rdfs:comment ?c . ?x a ?type .  FILTER (?type = owl:ObjectProperty)  } '
      (even when passing in bindings)
    • This forces us to be verbose, ie.
      q= 'SELECT distinct ?x ?l ?c WHERE { ?x rdfs:label ?l . ?x rdfs:comment ?c . ?x a ?type . FILTER (?type =  || ?type =  || ?type =  || ?type =  || ?type = ) } '
  2. TODO: work out how to do ".encode('UTF-8')" everywhere
  3. Be more explicit and careful re defaulting to English, and more robust when multilingual labels are found.
