Sivakatirswami,
Here is a link to a great pdf on XMP (Adobe's metadata). It has a section on External Storage of Metadata.
Quote "External Storage of Metadata":
It is suggested, though not required, that XMP metadata be embedded in the file that the metadata describes (as XMP Packets). There are cases where this is not appropriate or possible, such as database storage models, extremes of file size, or due to format and access issues. [...]
[...] The question arises of how to associate the metadata with the file containing the content.
Applications should:
1. Write the external file as a complete well-formed XML document, including the leading XML declaration.
2. The file extension should be .xmp . For Mac OS, optionally set the file's type to 'TEXT'.
3. If a MIIME type is needed, use application/rdf+xml.
4. Write external metadata as though it were embedded and then had the XMP Packets extracted and catenated by a postprocessor.
5. If possible, place the instance ID used in the rdf:about attribute within the file the XMP describes, so that format-aware applications can make sure they have the right metadata.
For applications that need to find external XMP files, look in the same directory for a file with the same name a s the main document but with an .xmp extension. (This is called a sidecar XMP file)
Pretty cool stuff,

FWIW,
The Actions in PS can handle writing to the Caption part etc. of multiple files in PS. It can also handle batch append and loading of .xmp files which can be saved/read/created in a text program.
Also, A great program for that many photos is Portfolio which I used for a CD project with a REV front end that had over 10,000 photos.

Does anyone know of a way to get Revolution to read and write to Adobe Photoshop's per image metadata?
real world scenario: our photographer in Nepal (world famous, doesn't just work for us) Thomas Kelly... we just sent him on assignment to Sri Lanka. He's back now and has a kaJillion digital images that he wants to caption inside PhotoShop. Opening the file info for each one of these in Photoshop is a "killer" process. I tried to have our managing editor consider having the metadata as a separate fooPhoto.psd /fooPhoto.txt document pair, for which I have many Rev apps that can easily preview thumbnailis and allow for data entry very quickly. And though one can see lot's of advantages of having this data as a separate file... the concept of the caption being part of the photo file itself seems to be "ingrained" as the only way to go...
