Dear all,
Just a very quick question about xmp sidecar interoperability between open source projects. I have seen a few e-mails lamenting the lack of interoperability - some commenting on the fact that some files are overwritten by others and that some simple data such as ratings can't get picked up by other projects.
I am not a coder - so have a simplistic view on this... And I'm trying to understand - but is there any real reason for this lack of interoperability?
In your opinions, what level of interoperability should be available between open source projects that use xmp sidecars? What would be your preferences on how they dealt with each other?
It just occurs to me that if we can fully define the problem, maybe we can encourage improvement.
The open source community may be large in itself, but the group of larger players in the open source photography management and/or manipulation side of things is probably still quite small in terms of projects and/or coders. Maybe we can get them to agree on methods to help improve xmp data collaboration between programs?
For me, at least, I would like to see the following:
* An agreed naming convention might help - to ensure that they don't tread on each others toes.
* Either one 'super' xmp file, that they all write into (but ignore the other program's data), or individual files, that are sufficiently differentiated that they don't overwrite each other.
* The ability to see if the file already has a star rating from another program and allow an option to transfer this to the new program.
* The ability to read tags/keywords and import them (and any hierarchies) if preferred.
* The ability to export all xmp data or embed it into the metadata of a derivative JPG or PNG etc (possibly including data from other programs too) when you export/convert a RAW file.
* Able to play nicely with non-free software, at the same time, without causing problems to their xmp files would be an advantage.
How about you folks? Any suggestions on what you would like to see? What would make life easier in terms of how you work and manage files between your open source programs (and even non-free programs)?
As I say, if we can define the issues, maybe we can address the problem with the relevant parties. Get them around the virtual table to talk etc.
Looking forward to hearing what suggestions or comments you might have.
Thanks,
Mark.
