1) The document discusses metadata and RDF standards like RDF and OWL that can be used to annotate data. 2) It proposes a new metadata model for OpenDocument format 1.2 that uses RDF to link elements in content files to descriptive metadata in separate RDF files. 3) It describes how OpenOffice.org 3 will support this metadata model through APIs and allow users to work with metadata through extensions.
