Dear all, I have uploaded a new version of the mapping table as a reference for the F2F meeting. In this version I have included updates and revisions for mpeg7, smtp, you tube, media rss, dig35, tva and CableLabs1.1 (which is more in use). When revising CalbeLabs1.1 (with some help) I noticed that one XMP-reference attribute correspond to many attributes in CableLabs (sometimes 20). The situation is the same for others such as TVA, MPEG7, EXIF etc. I think it is important to keep this in mind when we draft the mechanism of the Ontology. This issue is related to what Pierre-Antoine refers to "low-level" semantics: content of the return types vs. Syntax ( API return types, e.g. slash-separated string or structured sequence). I hope that we can find a solution to this problem during those days. Please post your opinions preferable before tomorrow noon! We have different types of mismatches; between the properties, data types and structure that can be solved by different parts of our standard. We use the following terms to refer to them: * High-level semantics = (ontology) Semantic links identified by the mapping table. * Low-level semantics = (content of the return types) Structure, e.g. representing one or several creators. * Syntax = (API) return types, e.g. slash-separated string or structured sequence Best regards Joakim ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Joakim Söderberg, M.Sc, Ph.D Multimedia Indexing Senior Research Engineer, Media Protocols and Applications Ericsson Research, Multimedia Technologies
