2020-01-27 15:20:44 +01:00
< li > It’ s difficult to decide some of these because the current CG Core 2.0 document does not provide guidance or rationale (yet)!< / li >
< li > Also, there is not a good Dublin Core reference (or maybe I just don’ t understand?)< / li >
2019-01-17 12:28:41 +01:00
< li > Several authoritative documents on Dublin Core appear to be:
< ul >
< li > < a href = "http://dublincore.org/documents/dces/" > Dublin Core Metadata Element Set, Version 1.1: Reference Description< / a > < / li >
< li > < a href = "http://www.dublincore.org/documents/dcmi-terms/" > DCMI Metadata Terms< / a > < / li >
2019-11-28 16:30:45 +01:00
< / ul >
< / li >
2019-01-17 12:28:41 +01:00
< li > And what is the relationship between DC and DCTERMS?< / li >
< li > DSpace uses DCTERMS in the metadata it embeds in XMLUI item views!< / li >
< li > We really need to look at this more carefully and see the impacts that might be made from switching core fields like languages, abstract, authors, etc< / li >
< li > We can check WorldFish and MELSpace repositories to see what effects these changes have had on theirs because they have already adopted some of these changes… < / li >
2019-01-17 18:53:00 +01:00
< li > I think I understand the difference between DC and DCTERMS finally: DC is the original set of fifteen elements and DCTERMS is the newer version that was supposed to address much of the drawbacks of the original with regards to digital content< / li >
< li > We might be able to use some proper fields for citation, abstract, etc that are part of DCTERMS< / li >
< li > To make matters more confusing, there is also “ qualified Dublin Core” that uses the original fifteen elements of legacy DC and qualifies them, like < code > dc.date.accessioned< / code >
< ul >
< li > According to Wikipedia < a href = "https://en.wikipedia.org/wiki/Dublin_Core" > Qualified Dublin Core was superseded by DCTERMS in 2008< / a > !< / li >
2019-11-28 16:30:45 +01:00
< / ul >
< / li >
2019-01-17 18:53:00 +01:00
< li > So we should be trying to use DCTERMS where possible, unless it is some internal thing that might mess up DSpace (like dates)< / li >
< li > “ Elements 1.1” means legacy DC< / li >
< li > Possible action list for CGSpace:
< ul >
< li > dc.description.abstract → dcterms.abstract< / li >
< li > dc.description.version → cg.peer-reviewed (or cg.peer-review-status?)< / li >
< li > dc.description.sponsorship → cg.contributor.donor< / li >
< li > dc.contributor.author → dc.creator< / li >
< li > dc.language.iso → dcterms.language< / li >
< li > cg.identifier.url → dcterms.identifier< / li >

< li > For example: < a href = "https://goo.gl/fb/VRj9Gq" > https://goo.gl/fb/VRj9Gq< / a > < / li >
< li > The full < a href = "http://id.loc.gov/vocabulary/relators.html" > list of MARC Relators on the Library of Congress website< / a > linked from the < a href = "http://dublincore.org/usage/documents/relators/" > DMCI relators page< / a > is very confusing< / li >
< li > Looking at the default DSpace XMLUI crosswalk in < a href = "https://github.com/DSpace/DSpace/blob/dspace-5_x/dspace/config/crosswalks/xhtml-head-item.properties" > xhtml-head-item.properties< / a > I see a very complete mapping of DSpace DC and QDC fields to DCTERMS
