Hi Gregory, Thanks so much for your comment. I am getting the sense that the general opinion is that there is not a lot to think about but simply converting ad hoc from XML if/when needed. I just had a look at the METS 2.0 documentation in GitHub and cannot really see any explicit/direct reference to Linked Data in it (although the original working group was interested in modelling the schema as a more LD-friendly schema). Nonetheless, the 2.0 documentation references hybrid/LD-compatible data exchange standard formats and protocols such as IIIF and BagIt, so who knows... I will post my question in the METS listserv, and see what they say. Thanks again!

[You don't often get email from [log in to unmask] Learn why this is important at https://aka.ms/LearnAboutSenderIdentification ] Hi Manuela, Personally I'd recommend storing and managing your METS documents as XML and converting to JSON only at the point where you need to process them as JSON. That assumes you have the option of storing as XML. If your database is built mainly or only for JSON, then you'll have to do a one-time conversion from XML to JSON. In any case, as has already been said it's strictly a matter of conversion, and there are lots of tools that can take XML and output generic JSON in a lossless way. Whether you would then need to have another process to go from JSON to JSON-LD I don't know; that's outside my knowledge.

Hello, I am posting this question on a couple of lists, so sincere apologies to those who might see it twice (or thrice). Does anyone know of any work that has been/is being/will be done on 'a' METS JSON-LD serialization? Any relevant info or comment in this re will be very much appreciated. Thank you!
