This is an experimental new codebase for specgen tools.
It depends utterly upon rdflib. See
If you're lucky, typing this is enough:
easy_install -U rdflib
and if you have problems there, update easy_install etc with:
easy_install -U setuptools
(Last time I did all this, I got Python errors but it still works.)
Inputs: RDF, HTML and OWL description(s) of an RDF vocabulary
Output: an XHTML+RDFa specification designed for human users
See and for details. --danbri
To test, see
This is quite flexible. use -h for help, or run all with ./
When working on a specific test, it is faster to use something like:
./ testSpecgen.testHTMLazlistExists
See the src for adding more tests (simple and encouraged!), or for
defining collections that can be run together.
"What it does":
The last FOAF spec was built using
This reads an index.rdf, a template.html file plus a set of per-term files,
eg. 'doc/homepage.en' etc., then generates the main HTML FOAF spec.
See also: (another rewrite)
- be usable at least for (re)-generating the FOAF spec and similar
- work well with multi-lingual labels
- be based on SPARQL queries against RDFS/OWL vocab descriptions
- evolve a Python library that supports such tasks
- keep vocab-specific hackery in scripts that call the library
- push display logic into CSS
- use a modern, pure Python RDF library for support
- we load up and interpret the core RDFS/OWL
- we populate Vocab, Term (Class or Property) instances
- we have *no* code yet for generating HTML spec
- mine the old implementations to understand what we need to know
about each class and property.
- decide how much of OWL we want to represent
- see what rdflib itself might offer to help with all this
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. Figure out the best way to do tests in Python. assert()? read diveinto...
3. TODO: work out how to do ".encode('UTF-8')" everywhere
4. Be more explicit and careful re defaulting to English, and more robust when
multilingual labels are found.
5. Currently, queries find nothing in SIOC. We need to match various OWL
and RDF ways of saying "this is a property", and encapsulate this in a
function. And test it. SIOC should find 20<x<100 properties, etc.
