Michele Mostarda commented on ANY23-65:
---------------------------------------
Hi Ben,
don't worry :) it happens, the RDFa 1.1 documentation is not so rich of
examples.
the rdfa.xslt is no longer maintained, we updated it with a partial support
for CURIES and then we decided to rewrite the RDFa extractor programmatically
[1].
Any23 chooses to use the legacy RDFaExtractor (based on rdfa.xslt) or the
RDFa11Extractor reading the property "any23.extraction.rdfa.programmatic" into
default-configuration.properties [2] . Such configuration can be changed also
programmatically, see [3].
If you find any issue and you want to provide any fix I suggest you to send us
a patch on [1] (complete of a regression test), being rdfa.xslt gradually
dismissed.
Thanks a lot for your feedback.

> Key: ANY23-65
> URL: https://issues.apache.org/jira/browse/ANY23-65
> Project: Apache Any23
> Issue Type: Improvement
> Affects Versions: 0.7.0
> Reporter: Ben Companjen
> Labels: patch, xslt
> Attachments: rdfa.xslt, stylesheet.patch, stylesheet3.patch
>
> Original Estimate: 3h
> Remaining Estimate: 3h
>
> The RDFa 1.1 Core specification requests namespace prefixes in HTML5 be put
> in a "prefix" attribute like this: "ns1: http://example.org/ ns2:
> http://example.com/";
> My sample HTML page has this, but Sindice, which uses Any23, didn't read my
> namespace correctly. I narrowed it down to, and changed accordingly, the XSLT
> template "tokenize2" in the rdfa.xslt stylesheet. The template expected
> "ns1:http://example.org/ ns2:http://example.com/"; (no spaces between prefix
> and namespace URI) and did not normalize whitespace, like linebreaks
> (although I'm not sure that broke the functionality).
> I use Any23 0.6.1 locally, but
> http://svn.apache.org/viewvc/incubator/any23/trunk/core/src/main/resources/org/apache/any23/extractor/rdfa/rdfa.xslt?revision=1231556&view=markup
> shows that the template is the same in the trunk.
> A possible problem may be that the new template will not accept the
> non-spaced namespace definitions, like you can find in the RDFa produced by
> Best Buy. A further improvement to my template may be accepting both
> namespace definitions with spaces and the ones without.
