What is the best practice for adding metadata to items added to an AGOL via referencing content items REST endpoints from an external portal or AGOL? Is it best to copy in the existing external metadata verbatim as-is? Or is that considered plagiarism? Clarification would be appreciated.
When I have added data from Portal to AGOL using the Rest URL the metadata came along with it and I can see it by going to the item detail page and accessing the URL from within AGOL.
