rdfpic currently only supports JPEG
metadata is stored as RDF
- stores metadata in JPEG "comment" chunks
- stores metadata in JPEG APP12 chunk for XMP
- reads/writes local files or URL (HTTP GET & PUT)
- form fields derived from RDF schema (config file)
- new schemas can be added on the fly
- Convert automatically EXIF information
With HTTP, reads image + RDF, but writes
only RDF
