Anglera + apollon
Keep apollon OMN as the PIM, DAM and workflow hub that approves product content and publishes it to shops, marketplaces and print. Add Anglera to fill the attribute values first, read from supplier documents with a citation on each, and written back through OMN's REST API into your existing approval workflow.
apollon and Anglera solve different halves of the problem — this page is about the seam between them.
