(cc'd Ben Litchfield, project admin of PDFBox, because he might be interested, too)
I'm about to start a little XMP framework (parser, DOM, merger, writer) which I need to finalize PDF/A (and later PDF/X) support for FOP. XMP is a subset of RDF defined by Adobe to provide a metadata storage format that is universally usable in many formats, PDF only being one of them. It can also be used with SVG and XSL-FO, although for the latter there are no recommendations on the placement of XMP metadata. This is something I will want to address when I gathered some experience with this topic. Since this XMP framework will be rather small and since it's not FOP-specific I wanted to ask if anyone is against my implementing it as part of XML Graphics Commons (org.apache.xmlgraphics.xmp)? I don't plan to use any RDF libraries as the XMP's RDF subset should be easily manageable with minimal code, i.e. no external dependencies other than JAXP's APIs. The main reason why I need this is that it should be possible to specify XMP inside an XSL-FO document. FOP should then use this info to populate the PDF Info object as well as the PDF Metadata object for the document. The metadata needs to be enriched with additional values which is why I need a parser and a easy-to-use in-memory representation. The thing could also be interesting for Batik, in case anyone wishes to port metadata from SVG over to the generated output files (PDF, EPS, PNG, TIFF etc.).
