WG: XSLT-Stylesheet for conversion XMP > MAWG

Dear Felix,

Since time-related datatypes  have to be used for date properties [1], I would choose option 1 or option 2.

Hi Martin,

this is on purpose. The values are not part of the lexical space of time-related datatypes in XML Schema. At
http://fabday.fh-potsdam.de/~sasaki/mawg/xmp/xslt/xml-canonical-to-mawg.xsl
I have created a function my:checkDateDataType, to deal with some of these values that occurred in the XMP example files. But the fallback is always that if no adequate datatype is found, I go to a string datatype.

I see two options:

1) Change the input data so that it contains only XML Schema dateTime compatible values
2) Extend my:checkDateDataType so that it deals with the two problematic values and converts them to dateTime values
3) Leave everything as is

My preference would be 2) or 3). 3) Would reflect reality most, at least given the XMP examples I have. Any thoughts?

Felix

Dear Felix,

your example looks very good now.
However, there is one thing left I would like to point your attention to:
There are two ma:date values with datatype xsd:string ("2010-12-13T12:59:59.12345<tel:59.12345>+02:00"^^xsd:string and "2010-12-31T11:59Z"^^xsd:string). A time-related datatype would be better at this point.

Best,
Martin

Thierry, Martin, all,

I implemented Martin's comments:
- input file with only one creation date value http://fabday.fh-potsdam.de/~sasaki/mawg/xmp/xslt/MAWG_test_canonical.xml
- XSLT transformation that solves the issues with multiple labels for ma:hasLanguage and ma:hasPolicy http://fabday.fh-potsdam.de/~sasaki/mawg/xmp/xslt/xml-canonical-to-mawg.xsl
- output in RDF/XML http://fabday.fh-potsdam.de/~sasaki/mawg/xmp/xslt/MAWG_test_canonical_mapped-to-rdf-by-xslt.xml
- output in TTL http://fabday.fh-potsdam.de/~sasaki/mawg/xmp/xslt/MAWG_test_canonical_mapped-to-rdf-by-xslt.ttl

Regards,

Felix

Sorry, Thierry, I don't remember the discussion with Werner  in detail. There is no label and no bag in

> ma:date "2009"^^xsd:gYear,
> "2010-11-18T11:57:24+01:00"^^xsd:dateTime,
> "2010-12<tel:2010-12>"^^xsd:gYearMonth,
> "2010-12-13T12:59:59.12345<tel:59.12345>+02:00"^^xsd:string,
> "2010-12-23T14:42:31"^^xsd:dateTime,
> "2010-12-31<tel:2010-12-31>"^^xsd:date,
> "2010-12-31T11:59:00"^^xsd:dateTime,
> "2010-12-31T11:59Z"^^xsd:string;

these are plain RDF statements. Could you clarify how to deal with the above?

Thanks,

Felix

Felix,


It is the same issue for all;
This was already discussed with Werner.
you should use  multiple time the same labels or avoid bags in your example.
