Re: [Exist-open] Indexing embedded metadata (XMP) with eXist ?

[Adam R. <ada...@de...>]

eXist is already capable of extracting the metadata from JPEG images, =
there is a function in the images extension module to achieve this. =
However, the information whilst accessible, is not currently indexed. =
Perhaps there is a larger subject of metadata in eXist here, I think =
users should be able to store user defineable metadata about a resource =
in a transparent manner. For images, PDF etc, part of this metadata =
could be the XMP.

Thanks Adam.

Not out of box, but I think it can be implemented without much effort.
eXist can store images or PDFs as binary objects. You could write a
trigger to pre-process those files before they are saved. The trigger
could extract the metadata and store it into an XML document. Or you
write an XQuery extension function for the job. I did something
similar with jpegs before. All you need is a Java library to help you
with the extraction.
