OpenOffice Metadata Extraction
Is there a plugin/config to extract metadata from OpenOffice documents and back?
I'm not aware of a plugin to extract metadata from OASIS document but it should'nt be too complicated as it uses XML files. You can write some code to open the file as a zip file, get the file meta.xml and parse it using SAX
Or you may be interested in a java library like jOpenDocument http://www.jopendocument.org/tutorial_metadata.html
