    • Type: New Feature

    • Priority: Minor
    • Resolution: Fixed
    • Affects Version/s: None
    • Fix Version/s: 10.10-HF21, 11.1
    • Component/s: S3
    • Release Notes Summary:
      Informative metadata are added to objects stored in S3 with new S3BlobProvider.

      When using the new S3BlobProvider (NXP-28460), blobs stored in S3 now have the following informative metadata automatically set:

      • Content-Type: MIME type
      • Content-Disposition: attachment; filename=...

      In addition, if the metadata.addusername part of the S3 connector XML configuration (or framework property nuxeo.s3storage.metadata.addusername) is set, the following Nuxeo-specific header is also set:

      • x-amz-meta-username: username

      These headers are not modified for subsequent changes to the document, they are only set the first time a given blob is written to S3.

      Description

      It could be useful for "backup" reasons to store some metadata with binaries. At least enough to be able to recover the original files (mime type, filename).

      It would make actually sense to store:

      • filename
      • mime type
      • put date
      • username of the session who did put the object

      Note that even if an object in S3 can be used by several documents in the database, having this information including the username can always be useful as most of the time there is a one-to-one mapping.
