Do something about large quantities of metadata

Description

We have several recently acquired datasets that have more metadata than Bio-Formats can handle. In some cases, this means 150+ MB of metadata alone; while this is OK when working on the command line, trying to import in ImageJ becomes a nightmare (especially since the importer feeds an OMEXMLMetadataStore to ImageReader, effectively doubling the amount of space needed to store metadata).

Ideally, we should come up with a solution that significantly reduces the amount of space required to store metadata, but doesn't require us to leave out any of the key/value pairs currently being stored.

  • Status changed from new to closed
  • Resolution set to fixed

r2922 disables automatic population of OriginalMetadata nodes in OMEXMLMetadataStore. For now, this solves the problem - when using ImageJ, the amount of memory needed for metadata is halved.
