NDLSH (National Diet Library Subject Headings) as Linked Data

Hello,

I forgot to announce that National Diet Library of Japan started to
provide its subject headings as Linked Data (Web NDLSH). The service
URI is http://id.ndl.go.jp/auth/ndlsh . This URI also serves as a
SPARQL endpoint. It contains about 1.3M triples for 100 thousands
headings.

The subject heading URI (NDLSH-URI) is the service URI plus slash and
subject heading ID (NDLSH-ID). For example, the NDLSH-ID for "Semantic
Web" is 01017771, thus http://id.ndl.go.jp/auth/ndlsh/01017771 is its
NDLSH-URI.

Web NDLSH accepts preferred label instead of NDLSH-ID as the local
part of the URI. For example,
http://id.ndl.go.jp/auth/ndlsh/セマンティックウェブ (Japanese for Semantic Web)
is owl:sameAs the previous one.

By dereferencing this URI, you'll get an HTML document or an RDF
description, depending on the accept header of your user agent. If you
add an extension e.g. ".html" or ".rdf" or ".ttl", a document with
according format will be returned.

Note this means an NDLSH is an information resource, not directly
denoting a real world entity, just like a Subject Indicator of Topic
Maps is.

cheers,
