Re: Re: ODS Meta Data

Hi Gannon,

I had the vision to provide one GRDDL file for creating an RDF graph 
(file) from the ODF files (content.xml, styles.xml and meta.xml) for all 
ODF and provide it on the OASIS site


Did not work for months on it and would be happy if you could have a 
review on this, before I work myself again into it and find a better on 
the OASIS site:
http://www.oasis-open.org/committees/download.php/30609/odf2rdf.xsl

A small command line test scenario  (5MB including Saxon.jar) can be 
found on the odftoolkit.org site:
http://odftoolkit.org/projects/odfdom/downloads/download/OpenDocument-v1.2-draft%252FODF_GRDDL_TEST.zip

PS: After a review of the test package today, I believe I need to 
document the test coverage better, to show that
a) I map all meta.xml elements and
b) all cases for the content (e.g. text content from a bookmark).

PPS: Must admit I did yet not fully understand your form mapping 
scenario. Perhaps you could you tell me what is missing in the GRDDL above?

Thanks,
Svante
