We've created a SharePoint O365 site for document management for our enterprise.
We've got 2 specific document types with required metadata. We've also created a library for one of these types to test from the type and removed the default type of document. The goal is to restrict uploads to not let the environment become a mess like we've got with older solutions.
We really want to force entry of required metadata with uploads, which we understand isn't a native capability. I'm sure others have had this need though so I'm hoping that someone can provided a technique for doing this. I'm talking about end-user uploaded - we can provide all required attributes through a tool.
Would triggers of some sort be a mechanism to catch uploads and validate metadata? Is there another technique? Are there several?
