Enhance UpdateMD web service to support DNX update
Currently, the updateMD web service is designed only for updating DC metadata. Updating DNX metadata is not supported. But tests have shown that DNX metadata can perfectly be updated using the updateMD web service – with the drawback, however, of losing some other DNX metadata such as Producer, Producer Agent, and Access Rights Policy. See attached file with a comparison of the IE METS before and after the updateMD process.
The getIE web service works fine in this regard, allowing you to choose between DC, DNX and source MD and giving you the complete metadata output.
We strongly argue that the updateMD web service should be developed further to support DNX metadata updates, too. The functionality is halfway there, so it shouldn’t take too much effort to make it complete.
