Report on metadata creation date in metadata quality summaries
Indexing fields for metadata quality reports do not include the upload date of the metadata they are reporting on. Therefor, summaries that are created, i.e. mean score for a user over time, currently show the time of the creation of the quality report, not the metadata.
Add the field 'mdq.metadata.timestamp' to application-context-mdq.xml to hold the metadata creation or update time.
Each quality suite will be responsible for making this information available in the quality report, so that MDQClient.saveRun
can record it.
