General Meta Data Profile, 1.1
About
This document defines meta data properties to be used in linking documents. These properties describe relationships between the source document and the linked data.
To use these properties in an HTML-based document, you must define this resource as a profile in your document. This is done by adding the URL of this document to the profile attribute of the head element. For example, the head start tag may look like this: <head profile="http://www.webdevout.net/profile/1.1/">.
The top-level properties listed below may be used in the name attribute of meta elements. The values of those properties are put in the content attribute.
The properties under rel
may be used to describe relationships with whole documents. In HTML, the property names may be used in the rel or rev attributes of linking elements (link and a).
The properties available for use in linking elements are not necessarily limited to the properties defined in this profile. If the document language allows it, multiple meta data profiles may be used for a single document. HTML 4 also defines a standard list of link types that may be used in addition to the properties under rel
.
