I’m trying to use an Omeka-s JSON output (for this: http://studiecollectie.momu.be/api/items?resource_item_sets/11) into a system that’s normally converts json files to xml first.
But it fails and gives me this log information/
Started json -> xml conversion.
Error during json processing
Reading of entry itemsExportAPI.json failed.
Prefixed elements must have namespace URIs.
Any ideas what causes this? And if I can perhaps manually ‘tweak’ the JSON file so that it would work?
