I think there are two strategies here 1.) Store the generated jp2 in a bitstream, create your own bundle, name it whatever you want or store it next to the existing bitstream in the content bundle if you want to also share the generated file for others to use. Then expose the filesystem location of the file to your adore-jakota viewer.
2.) Store the generated jp2 file in an external directory that can be calculated and rather than storing anything about this detail in the Item, come up with a way to calculate the location of that file, if it exists, then show your viewer. (1) violates the storage layer boundary of DSpace, in the future you may not have filesystem access to that file, but your getting the benefit of storing the jp2 file in the assetstore as well. (2) is more respectful of the storage boundary and but doesn't assure any preservation storage of your generated file within DSpace. I would choose 2 over 1 because it separates your implementation from dspace internals, and in XMLUI can be implemented entirely in the theming tier You could take your own approach and generate a bundle/bitstream with some sort of file system reference to the file. But there may be less chance of breakage by repo managers if its a calculated reference rather than a stored reference. I like (2) and if we had the development resources, I'd promote the idea that we should have more than one possible "storage" tier for DSpace, allowing maintainers to create there own separate storage locations for derivatives that may require specific storage/access requirements and access to by other applications. The work you do here could go to producing such an API. Cheers, Mark On Wed, Apr 21, 2010 at 2:55 PM, John Preston <byhisde...@gmail.com> wrote: > Hi, I am seeking a little guidance here.
