embedded metadata in images is one of the strategies i, as a blind netizen, support, for it would make possible a "central depository" which can be used to compare and/or overwrite the embedded metadata -- something akin to the database search one routinely performs for an audio CD; where multiple results are returned, one simply reviews each result, and picks that which best fills/meets one's needs at that particular time so, submitted for the TF's information stroke consideration: RDFPic is a tool developed by the W3C to embed an RDF description of a picture into the picture itself, as described by describing and retrieving photos using RDF and HTTP (http://www.w3.org/TR/photo-rdf/). The version in CVS supports XMP. the tool and documentation can be obtained from: http://jigsaw.w3.org/rdfpic/ even if you don't care about the tool, nor know that much about RDF, i highly recommend reading: http://www.w3.org/TR/photo-rdf/ the Abstract of which states: QUOTE This note describes a project for describing & retrieving (digitized) photos with (RDF) metadata. It describes the RDF schemas, a data-entry program for quickly entering metadata for large numbers of photos, a way to serve the photos and the metadata over HTTP, and some suggestions for search methods to retrieve photos based on their descriptions. The data-entry program has been implemented in Java, a specific Jigsaw frame has been done to retrieve the RDF from the image through HTTP. The RDF schema uses the Dublin Core schema as well as additional schemas for technical data. We already have a demo site and there is sample source code available for download. The system can be useful for collections of holiday snapshots as well as for more ambitious photo collections. UNQUOTE
