Bram Luyten (@mire) commented on DS-433:
----------------------------------------
Some initial comparing work:
https://wiki.duraspace.org/display/cmtygp/NewDublinCore
In short:
- there seems new & more focus on Domain (limitations on the type of resources
a field can be used for) and Range (which values are allowed as contents of a
field)
- For the older set of 15 DC elements, it just seems a matter of
implementing/enforcing range on some of the properties (e.g. ensuring correct
dc.date values, language values, ...)
- Lots of the newer DC Terms are already present in DSpace. Like many of DSpace
qualified dates, like dc.date.issued dc.date.available, are now defined as
individual elements. This is a great opportunity to ensure that no information
gets lost while element qualifiers do get lost when harvesting.
- DCMI still seems to struggle with the idea of relations between fields. Some
fields are indicated that they should be used with non-literal values (e.g.
things instead of strings) but they haven't come up with a formal range
declaration.

> Key: DS-433
> URL: https://jira.duraspace.org/browse/DS-433
> Project: DSpace
> Issue Type: Improvement
> Components: DSpace API
> Reporter: Jeffrey Trimble
> Priority: Major
> Original Estimate: 17 weeks, 2 days, 8 hours
> Remaining Estimate: 17 weeks, 2 days, 8 hours
>
> DSpace's current implementation of Dublin Core was a subset or simplified
> version of the Dublin Core standard created by OCLC. Since the first release
> of DSpace, Dublin Core has undergone major revisions. DC version 1.1 was
> implemented in 2007 with 15 base elements a subset of the larger DCMI. Some
> users are currently misusing the DC standards, or lack knowledge how to use
> it properly due to the age of the current element set and the descriptions
> contained therein.
> I recommend that the DSpace Developers look at using the full implementation
> of DCMI for the next major release after 1.6. Additionally tools will need
> to be provided
> for conversion of existing DC Metadata Schema.
> Also, it would be advantageous to build into the software a validation of DC
> elements in a stricter sense than is now being used.
