Can I update metadata only with updatedocument API?

I'd like to update document's metadata only without re-uploading document itself.

So, I use updateDocument API without "File" parameter to update metadata only, but unfortunately enrich data is gone. (metadata is successfully updated!).

Is this updatedocument api's spec? If I want to update metadata. Do I need upload document itself?

Solution

  • Unfortunately, Discovery does not support updating only the metadata.

    As you speculate, you do need to re-upload the document itself, along with the new or updated metadata that you want.

    This documentation says:

    Update a document

    Replace an existing document. Starts ingesting a document with optional metadata.

    which I can see may not be completely clear. By saying Replace an existing document it is trying to convey that the existing document is always and completely replaced.
