Hi all, I'm working with Commons Machinery [1] on developing free software that aims to provide ways of easily attributing digital works (in existing tools too). As part of this, we've made a prototype LibreOffice extension [2] that enables pasting images together with metadata into Writer. We also have a Firefox add-on that can copy both metadata and image to clipboard [3]. The metadata is copied alongside the image as an additional clipboard object of mimetype "application/rdf+xml".
This actually works pretty well on Linux, where the initial prototype was developed. RDF data is accessible from the extension as a ByteSequence object wrapped in a DataFlavor returned by the clipboard instance. However, on Windows, the metadata is unavailable, apparently because the clipboard only shows DataFlavors which have been successfully processed by CDataFormatTranslator class in dtrans. After some hacking, I found out that adding "application/rdf+xml" mimetype to translation table in dtrans/source/win32/ftransl/ftransl.cxx makes the type appear among the data flavors on Windows. The solution doens't look very elegant, so first, I'd like to know if there exists a better way to access non-standard data in clipboard under Windows. If no such way exists, I wonder, if dtrans could be patched to support "application/rdf+xml" mimetype upstream? Or if there is a more general solution? I found a related discussion from 2011 [4][5], but there doesn't seem to be any conclusion to that. I'd appreciate any feedback and thoughts on the matter.
