Google Mini doesn’t support XMP
Recently, I corresponded with a Google engineer about XMP support in the Google Mini. At work we have a need for robust, finely-tuned search and retrieve capability leveraging Adobe’s XMP in PDF documents. I gave the engineer an example document tagged with custom metadata, explained how we’re currently using a solution which involves Windows Indexing Services, Adobe’s iFilter, and IFilterShop’s PDF+ iFilter to index PDF documents tagged with custom metadata, and VBscript/ASP/IIS for search and retrieval. (Our solution works but the relevance of our search results is mixed.) The engineer ran the example document through the Mini and it would appear that the Mini isn’t aware of XMP schemas and doesn’t support custom schemas, though they are going to consider it for a future release.
For the record, the Mini does support Dublin Core metadata within PDF files, which includes author, creator, subject, etc. The Google Mini looks like a tremendous value for small-scale indexing and searching.
