License and rights statements

- DCAT 2014 handling of license and rights do not appear to satisfy all requirements [[VOCAB-DCAT-20140116]]. - The recently completed W3C ODRL vocabulary [[ODRL-VOCAB]] provides a rich language for describing many kinds of rights and obligations. - In this chapter it is planned to describe some patterns for linking DCAT Datasets and/or Distributions to suitable rights expressions. - See the wiki page on License and rights for more discussion. -

+ DCAT 2014 handling of license and rights do not appear to satisfy all requirements [[VOCAB-DCAT-20140116]]. + The recently completed W3C ODRL vocabulary [[ODRL-VOCAB]] provides a rich language for describing many kinds of rights and obligations. + In this chapter it is planned to describe some patterns for linking DCAT Datasets and/or Distributions to suitable rights expressions. + See the wiki page on License and rights for more discussion. +

+

+ Selecting the right way to express conditions for access to and re-use of resources can be complex. + Implementers should always seek legal advice before deciding which conditions apply to the resource being described. +

+

+ This specification distinguishes three main situations: one where a statement is associated with the resource that is explicitly declared as a 'licence'; + a second where the statement is not explicitly declared as a 'licence'; and a third where the conditions are explicitly expressed as an ODRL Policy. +

+

+ The following approach is recommended: +

    +
  1. use dct:license to refer to well-known licences such as those defined by Creative Commons
    + The object of dct:license, a dct:LicenseDocument, is "A legal document giving official permission to do something with a Resource."
  2. +
  3. use dct:rights to refer to rights statements that are not licences, such as copyright statements
    + The object of dct:rights, a dct:RightsStatement, is "A statement about the intellectual property rights (IPR) held in or over a Resource, a legal document giving official permission to do something with a resource, or a statement about access rights." + This is more general than a dct:LicenseDocument and therefore should be used if it the statement contains more general information about rights.
  4. +
  5. use odrl:hasPolicy for linking to ODRL policies
    + The Open Digital Rights Language (ODRL) is a policy expression language that provides a flexible and interoperable information model, vocabulary, and encoding mechanisms for representing statements about usage (i.e. permissions, prohibitions, and obligations) of content and services.
