This sounds doable, but for now it might be easier simply to patch the
four scripts hitherto used to generate the four RDF schemas.
I have restored the following files to their state just before they
were deleted circa May 21:
- 2012-05-17 22:50 211 2012-05-21/headers/header-rdf-dcam.xml
- 2012-05-17 22:50 207 2012-05-21/headers/header-rdf-dcelements.xml
- 2012-05-17 22:50 189 2012-05-21/headers/header-rdf-dcterms.xml
- 2012-05-17 22:50 182 2012-05-21/headers/header-rdf-dctype.xml
- 2012-05-17 22:49 10090 web/xsl/common-templates.xsl
- 2012-05-17 22:49 2613 web/xsl/dcam.xsl
- 2012-05-17 22:49 1797 web/xsl/dcelements.xsl
- 2012-05-17 22:49 3608 web/xsl/dcterms.xsl
- 2012-05-17 22:49 1414 web/xsl/dctype.xsl
The repository [3] is up-to-date with these recent changes.
Then I compared:
-- Ntriples generated from the RDFa/HTML document [1]
-- Ntriples generated from the RDF/XML produced by the scripts above (e.g., [2])
and find only two things that would need to tweaked to make the XSL scripts produce
identical triples:
-- Datatypes for dates
s/"2008-01-14"/"2008-01-14"^^<http://www.w3.org/2001/XMLSchema#date>/
-- Language tags for text (e.g., description, label, skos:note, title...)
s/@en-us/@en/
I can then edit header-rdf-* and the scripts should generate four RDF schemas
with triples identical to triples distilled from [1].
Gregg, are there perhaps changes to build.xml (to remove generation of the
RDF schemas) that would need to patched back in?
How easy would it be to make these fixes?
