You might have been wondering why I’ve been banging on about XMP here. Why the emphasis on one vendor technology on a blog focussed on an industry linking solution? Well, this post is an attempt to answer that.
Four years ago we at Nature Publishing Group, along with a select few early adopters, started up our RSS news feeds. We chose to use RSS 1.0 as the platform of choice which allowed us to embed a rich metadata term set using multiple schemas - especially Dublin Core and PRISM. We evangelized this much at the time and published documents on XML.com (Jul. ’03) and in D-Lib Magazine (Dec. ’04) as well as speaking about this at various meetings and blogging about it. Since that time many more publishers have come on board and now provide RSS routinely, many of them choosing to enrich their feeds with metadata.
Well, RSS can be seen in hindsight as being the First Wave of projecting a web presence beyond the content platform using standard markup formats. With this embedded metadata a publisher can expand their web footprint and allow users to link back to their content server.
Now, XMP with its potential for embedding metadata in rich media can be seen as a Second Wave. Media assets distributed over the network can now carry along their own metadata and identity which can be leveraged by third-party applications to provide interesting new functionalities and link-back capability. Again a projection of web presence.
