Repository API - Is there a way to update a Document's Meta Data
By using Repository API to connect to a third part Enterprise Content Management System (ECM), is there a way to set document metadata via the Repository API?
The way that I have seen the documentation, as well as PoC's done, it feels like the Repository API is really treating the repository like a filesystem.
E.g., if a OOTB Connection to Azure Storage Account is made by making it a Repository, how can I set metadata for the files that I have uploaded into Azure?
