Any ideas if this feasible and how I could go about it ?? It sure looks feasible to me, and is something I have thought about adding. Others have already given some thoughts on how to get the information into the PDF. I agree with Dirk-Willem that that writing it directly into the PDF (along with all of the other FOP output) is the better way to go. The other issue is how to get the info into the FO file. It seems to me that this will require an extension, so be sure to check out http://xml.apache.org/fop/extensions.html if you haven't already. Getting the data into the PDF should be quite easy with an extension. The bookmark extension is a more complicated example of the sort of thing needed. Your extension element would contain the xmp data xml information which is put into a pdf stream of type Metadata. The difficult part is creating the xmp data, whatever it is. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]

Just take generated pdf and process it as you wish using third-party software (iText is a good one). -- Oleg Tkachenko eXperanto team Multiconn Technologies, Israel - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]

See: http://www.adobe.com/products/xmp/main.html for more details. But this is really just RDF. http://partners.adobe.com/asn/developer/xmp/pdf/MetadataFramework.pdf Page 12 sums it all up in general. And in http://partners.adobe.com/asn/developer/xmp/download/docs/XMPEmbedding.pdf you will find exactly how to put it into PDF. Any ideas if this feasible and how I could go about it ?? Well; two methods; the first one (which is easiest but gets you little in return) would be it integrate the adobe SDK with apache by using their library interface. However it would be very limited to a few platforms and propably not worth your time and a nightmare to maintain. The second method is to read and study the XMPEmbedding.pdf spec and start to code that directly into FOP. In the medium and long run that is propably the quickest route; and luckily the standard is quite simple. Once you've got something working - just post the patch on this list. If there are -any- licenseing questions around this community; [EMAIL PROTECTED] is the place to ask; and/or [EMAIL PROTECTED] And they will use watherver legal cycles to make sure it is all sound. Alternatively - there are plenty of small commercial outfits in the apache ecosystem which would be happy to simply implement this for you and if permitted by the customer would make it open source later. Of course - wether this code ever makes it into FOP depends on if most of the developers reach consensus as to wether this is a cool feature.
