Anglo-American Cataloguing Rules (AACR), RDA: resource description and access ...

[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)
