Introduction

Changes From Previous Version

• 2005-08-10 - editorial change by Ian Davis: "Added isDefinedBy properties and updated documentation"

Namespace

The URI for this vocabulary is

http://purl.org/vocab/frbr/extended#

When used in XML documents the suggested prefix is frbre

Each class or property in the vocabulary has a URI constructed by appending a term name to the vocabulary URI. For example:

http://purl.org/vocab/frbr/extended#complementsExpression
http://purl.org/vocab/frbr/extended#AutonomousWork

The term name for a class always starts with an uppercase character. Where the term name is comprised of multiple concatenated words, the leading character of each word will be an uppercase character. For example:

AutonomousWork
ReferentialWork

The term name for a property always starts with an lowercase character. Where the term name is comprised of multiple concatenated words, the leading character of the second and each subsequent word will be an uppercase character. For example:

complementsExpression
complementsWork

Summary of Terms

This vocabulary defines 4 classes and 52 properties .
