WHAT

http://cvs.berlios.de/cgi-bin/viewcvs.cgi/xfolio/webapp/transform/meta/xmp2dc.xsl

Wiki Markup
AdobeTM applications (and some other freewares like \[pixvue\]) promote an XML schema of metadatas (title, author, description...) embed in binary files (jpeg, pdf, and other proprietary format). The info is interesting, using a semantic knowed as \[IPTC/IMM\], but the XML is ugly. This transformation try to extract most of the fields in a flat XML record conforming to dublincore recommandations. This becomes interesting when you can get some xmp. It's usually possible with some tricks in AdobeTM apps,  but hopefully, a cocoon generator is also exposed here for jpeg images
\[XfolioXMPGenerator\]

There's a specific feature in this transformation. In our context, we expect multilingual records (title and description in more than one language). You can imagine the interest. If you have an image with a tree, if the content is indexed in a search engine, you can find the images documented with the term "tree". If you are waiting for other langs public, it's also nice to have the term "arbre", or "baum". A very simple text rule is supported, precised in the HOW section. This transformation have been tested on some hundred of jpeg images.

\[XMP\] Adobe Systems Incorporated "Extensible Metadata Platform (XMP)"  http://www.adobe.com/products/xmp/main.html  Adobe's Extensible Metadata Platform (XMP) is a labeling technology that allows you to embed data about a file, known as metadata, into the file itself. With XMP, desktop applications and back-end publishing systems gain a common method for capturing, sharing, and leveraging this valuable metadata -
opening the door for more efficient job processing, workflow automation, and rights management, among many other possibilities. With XMP, Adobe has taken the "heavy lifting" out of metadata integration, offering content creators an easy way to embed meaningful information about their projects and providing industry partners with standards-based building blocks to develop optimized workflow solutions.

The Dublin Core metadata element set is a standard for cross-domain information  resource description. Here an information resource is defined to be "anything  that has identity". This is the definition used in Internet RFC 2396,  "Uniform Resource Identifiers (URI): Generic Syntax", by Tim Berners-Lee et al.  There are no fundamental restrictions to the types of resources to which Dublin  Core metadata can be assigned.

This document provides guidelines for people implementing Dublin Core metadata  applications using XML. It considers both simple (unqualified) DC and qualified  DC applications. In each case, the underlying metadata model is described  (in a syntax neutral way), followed by some specific guidelines for XML implementations.  Some guidance on the use of non-DC metadata within DC metadata applications is also provided.
