The OLAC Metadata standard [OLAC-Metadata] follows the generic resource description standard known as "Qualified Dublin Core" [DCQ], and supports a powerful extension mechanism described in [OLAC-Extensions]. Any party may develop their own metadata extension and use it in OLAC metadata records. This document lists the third-party extensions which are known to work with OLAC Metadata. Each extension is described in terms of a title and the following five attributes:
The symbolic name that is used as the value of the xsi:type attribute to indicate that the extension is being used in a metadata element.
The latest revision date of the extension or its controlled vocabulary.
- Applies to
The Dublin Core elements with which the extension may be used.
A summary description of what the extension is used for.
A link to a complete document that defines and exemplifies the extension. If the extension involves a controlled vocabulary, the document should also enumerate and define the terms of the vocabulary.
There are currently no third-party extensions.
The following hypothetical third party extensions are provided as examples:
|[DCQ]||Dublin Core Qualifiers.
|[OLAC-Extensions]||Recommended metadata extensions
