• Update current “DCMI Terms” metadata registry to QDC
  • provide brief definition and reference (link?) for "DCMI Terms" and "QDC"
  • "DCMI Terms" is the name of the metadata registry that ships with DSpace. It was designed to comply with the draft Library Application Profile for Dublin Core, modeled on the flat, extensible Qualified Dublin Core standard. The Soon after, the Dublin Core Metadata Initiative (DCMI) subsequently updated its Qualified Dublin Core (QDC) standard provide brief definition and reference (link?) for "DCMI Terms" and "QDC"standard. 
  • provide reasoning - why is compliance with QDC (ultimately DCTERMS) important/desirable
  • Updating QDC to the latest standard of DCMI and Standardizing the default namespaces were identified as a priorities in the October 2011 community survey on improving metadata support authored by DCAT at the request of the DSpace Committers/Developers. These updates were seen as standardizations that "would help compatibility with other systems and benefit from information gathered by the DCMI community" and would adress the problem of broken compliance with the standard Dublin Core, which had affected portability to/from a repository.
  • provide a few specific examples of what fields would change from/to, perhaps identify some of what the basic differences would be from current DCMI
  • Updates range from the very basic (change dc.identifier.citation to dc.identifier.bibliographicCitation; dc.description.provenance to dc.provenance; dc.date.copyright to dc.date.copyrighted) to the addition of QDC elements like dc.accrualMethod and dc.audience. If we are continuing to allow qualifiers to be added to QDC elements in the registry, we may also continue to support the current qualified elements that are not specifically compliant with QDC (e.g., dc.contributor.editor).

• Add DCTERMS as new, parallel metadata registry
  
  • provide brief definition and reference (link?) for "DCTERMS"
  • DCMI has not updated its Qualified Dublin Core standard since 2005. The community standard has shifted towards DCTERMS.
  • provide reasoning - why is compliance DCTERMS important/desirable
  • provide a few specific examples of what fields would change from/to, perhaps identify some of what the basic differences would be from current DCMI
• Lockdown registries, offering migratory tools to pull out local customizations and push into new local schema. Make it possible but not easy to delete or edit elements in QDC and DCTERMS registries. Continue to enable the addition of qualifiers in the QDC registry
• Clarify end result - how many metadata registries DSpace will ship with – 3?: 
  
  • 1) QDC - which will be an up date of the current DCMI, and will set as the default metadata schema 
  • 2) DCTERMS - which will be an optional metadata schema, ultimate goal of replacing QDC at some point in the future
  • 3) Local schema - which would ship empty, for the purpose of local customizations
