Specific questions

DCMI Metadata Terms in the /terms/ Namespace
-- Expression of owl:equivalentProperty
3. AOB
======================================================================
Changes in DCMI Metadata Terms
-- Akira noticed that Pete's rationale for changes to the comments
for dcterms:contributor, dcterms:creator, and dcterms:publisher,
which was copied verbatim into the decision document, contained
a sentence -- "See [1] for an example of this confusion" -- with
no reference for "[1]". To compound the confusion, the JISCMAIL URIs
appear to have changed, so that Pete's original posting is no longer
where Akira found it [*], but at [**]. Solution: removed sentence
with the missing reference from [***]
[*] https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=ind0903&L=DC-USAGE&P=982
[**] https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=ind0903&L=DC-USAGE&P=1111
[***] http://dublincore.org:8080/usage/decisions/2010/dcterms-changes/index.shtml
-- As per Akira's suggestion, changed wording in rationale for dcterms:title
range from
".. be be rendered in more than one writing system."
to the less controversial
".. be be rendered in more than one script."
in http://dublincore.org:8080/usage/decisions/2010/dcterms-changes/.
-- Corrected references to ISO 15836 [1] and ANSI/NISO Z39.85 [2].
These were already corrected by hand, with an errata note, in the
stand-alone DCES document [3], which will now be re-published (without
the errata note) as [4].
I have corrected these references in the xsl source used to generate
the updated DCMI Metadata Terms [5].

[5] http://dublincore.org:8080/usage/decisions/2010/dcterms-changes/
-- Jacco van Ossenbruggen noticed that the non-existent class
dcterms:Collection was used as a domain for accrualPolicy,
accrualPeriodicity, and accrualMethod, I have corrected this
to dcmitype:Collection (http://purl.org/dc/dcmitype/Collection)
in the source file [1], so the changes will show up in [2].
This change is documented in [3].

-- New Syntax Encoding Scheme for RFC 5646.
As decided in the June call, created the datatype http://purl.org/dc/terms/RFC5646
following the precedents of dcterms:RFC1766, dcterms:RFC3066, and dcterms:RFC4646.
-- Added range of dcam:memberOf:
dcam:memberOf rdfs:range dcam:VocabularyEncodingScheme
-- Asserted the equivalence of dcterms:creator and foaf:maker
Added to the Decision document:
RESOLVED: That in agreement with the maintainers of the
FOAF vocabulary, which have added to FOAF the assertion
foaf:maker owl:equivalentProperty dcterms:creator
DCMI will assert:
dcterms:creator owl:equivalentProperty foaf:maker
The URIs are:
http://xmlns.com/foaf/0.1/maker
http://purl.org/dc/terms/creator
-- NOTE: Added a new tag <EquivalentProperty> to XML source
of term description, dcterms-properties.xml. Will add the
information both to the Web pages and the RDF schemas by
hand for now.
-- The introductory text of DCMI Metadata Terms was
edited to add "Equivalent Property".
======================================================================
Changes in RDF schemas
-- ** PENDING USAGE BOARD APPROVAL **
Changed titles of RDF schemas. Having just drafted a
glossary entry [1] about DCMI usage of the concept "DCMI
Namespace", I couldn't help noticing that the titles of
the RDF schemas use "DCMI Namespace" in a way that is
arguably wrong...
-- Changed from:
DCMI Namespace for metadata terms related to the DCMI Abstract Model
DCMI Namespace for the Dublin Core Metadata Element Set, Version 1.1
DCMI Namespace for metadata terms in the http://purl.org/dc/terms/ namespace
DCMI Namespace for metadata terms of the DCMI Type Vocabulary
-- To:
Metadata terms related to the DCMI Abstract Model
Dublin Core Metadata Element Set, Version 1.1
DCMI Metadata Terms in the /terms/ Namespace
DCMI Type Vocabulary
[1] https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=ind1009&L=DC-GLOSSARY&P=6753
-- With dcterms:publisher, used "http://purl.org/dc/aboutdcmi#DCMI"
instead of the value string "The Dublin Core Metadata Initiative".
-- Corrected an error in generating the RDF representation
of dcterms:title, the definition of which was presented
using dcterms:description instead of rdfs:comment, as the
other properties.
