I've been thinking about creating a FOSS photo diary application and am considering storing notes that the user makes in XMP metadata inside the file
It's important that this information is kept as it can be of high value for the user. Do you know if storing metadata in XMP is future safe? For how long time can this standard be expected to remain so that the user is able to read the metadata?
I'm thinking of using jpg as well as png files in the application
Grateful for help with this!
