Gordon DunsirePresented at AKM 15, Porec, 2011
Content standards
Instructions/rules on creating and maintaining the content of bibliographic metadata (records)
Aim to improve consistency, coherency, and completeness of recordsFor resource discovery services
Different standards for different domains (archives, libraries, museums)And different contexts and changes over timeE.g. International Standard Bibliographic Description (ISBD),
Anglo-American Cataloguing Rules (AACR), RDA: resource description and access ...
Example: ISBD consolidated edition 2011
The place of publication, production and/or distribution is the name of the place associated on the prescribed source of information with the name of the publisher, producer or distributor.

Everything expressed inResource Description Framework (RDF)
[real soon now: ISBD/DCMI collaboration]
RDF triple
Subject : Predicate (property) : Object
Metadata content:This book (URI) : Has author (URI) : That author (URI)
URI : URI : URI (Linked data!)/Literal (Display)
Element semantics:Has author (URI) : Has definition (URI) : “Relates …”
RDF graph
Subject URI
Object URIProperty1 URI
Object literalProperty2 URI
Application (profile) semantics:
Has title(URI)
has minimum occurrence(URI) “1”
“1”has maximum occurrence
(URI)
= mandatory,non-repeatable
Record content:
This book(URI)
“Museum archives”
has title(URI) Author1 (URI)
has creator (URI)
Author2 (URI)has contributor (URI)
Linking data from different domains
= linking data from different graphs
Author1 (URI)
AuthorX (URI)
is same as (URI)
is same as (URI)
