RDF vocabularies Current Status

This page summarizes the relationships among specifications, whether they are finished standards or drafts. Below, each title links to the most recent version of a document.

Completed Work

W3C Recommendations have been reviewed by W3C Members, by software developers, and by other W3C groups and interested parties, and are endorsed by the Director as Web Standards. Learn more about the W3C Recommendation Track.

Group Notes are not standards and do not have the same level of W3C endorsement.



ODRL Information Model 2.2

The ODRL permissions and obligations expression language provides a flexible and interoperable information model, vocabulary, and encoding mechanisms for describing statements about digital content usage. The ODRL Information Model describes the underlying concepts, entities, and relationships that form the foundational basis for the semantics of the ODRL statements .


ODRL Vocabulary & Expression 2.2

The ODRL permissions and obligations expression language provides a flexible and interoperable information model, vocabulary, and encoding mechanisms for describing statements about digital content usage. The ODRL Vocabulary and Expression describes the terms used in such statements and how to encode them.


The RDF Data Cube Vocabulary

There are many situations where it would be useful to be able to publish multi-dimensional data, such as statistics, on the web in such a way that it can be linked to related data sets and concepts. The Data Cube vocabulary provides a means to do this using the W3C RDF (Resource Description Framework) standard.


Data Catalog Vocabulary (DCAT)

DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. This document defines the schema and provides examples for its use.


The Organization Ontology

This document describes a core ontology for organizational structures, aimed at supporting linked-data publishing of organizational information across a number of domains. It is designed to allow domain-specific extensions to add classification of organzations and roles, as well as extensions to support neighbouring information such as organizational activities.

Group Notes


vCard Ontology - for describing People and Organizations

The document describes a mapping of the vCard specification (RFC6350) to RDF/OWL. The goal is to promote the use of vCard for the description of people and organisations utilising semantic web techniques and allowing compatibility with traditional vCard implementations.


Asset Description Metadata Schema (ADMS)

ADMS is a profile of DCAT, used to describe semantic assets (or just 'Assets'), defined as highly reusable metadata (e.g. xml schemata, generic data models) and reference data (e.g. code lists, taxonomies, dictionaries, vocabularies) that are used for eGovernment system development.


Registered Organization Vocabulary

This is a vocabulary for describing organizations that have gained legal entity status through a formal registration process, typically in a national or regional register. This document is the normative companion to the namespace document at http://www.w3.org/ns/regorg.


Linked Data Glossary

The Linked Data Glossary contains terms defined and used to describe Linked Data, and its associated vocabularies and best practices related to publishing structured data on the Web using open Web standards.


Below are draft documents: other Working Drafts . Some of these may become Web Standards through the W3C Recommendation Track process. Others may be published as Group Notes or become obsolete specifications.

POE Use Cases and Requirements

This document includes a set of use cases and requirements, compiled by the Permissions & Obligations Expression (POE) working group, that motivate the expression of statements about digital content usage. All use cases provide realistic examples describing how people and organisations may (or want to be able to) specify statements about digital content usage. The requirements derived from these use cases will be used to guide the development of the POE WG recommendation deliverables for the Information Model, Vocabulary and Encodings.


Terms for describing people

This document defines a set of terms for describing people. It defines how to describe people's characteristics such as names or addresses and how to relate people to other things, for example to organizations or projects. For each term, guidance on the usage within a running example is provided. This document also defines mappings to widely used vocabularies to enable interoperability.
