General Meta Data Profile, 1.2

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/1.2/">.

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.

rel

advisory: Information about content contained in the current document or child documents as it relates to being potentially inappropriate for certain audiences.
author: Information about an individual or group that participated in the formation of the document's content.
child: A document whose topic is bounded by the broader scope of the current document.
comments: A document that contains public discussion about the current document.
icon: A document that provides a graphical branding for the current document.
license: Information about a license describing legally acceptable use of the document.
nofollow: A document whose link was added to the current document by an unaffiliated source and cannot be confirmed to have relevance with the current document.
parent: A document whose topic's broader scope bounds the current document.
prefetch: A document that is popularly requested after the current document, although it may not necessarily be the next document in a structural sequence.
shortcut: This modifies an attached link type to refer to links made to the current document, rather than the document itself. For example, shortcut icon would designate a graphic to be used specifically in links to the document. Authors should avoid using this link type except where necessary to direct older user agents to the appropriate information.
sibling: A document, other than the current document, whose topic is bounded by the broader scope of the document whose topic likewise bounds the current document. A sibling is a child of the current document's parent, not including the current document.
