This document defines meta data properties to be used in semantic documents. These properties describe the nature of the relationship between the source document and the associated 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 profile 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/1.5/">
.
The top-level properties listed below, other than “rel”, may be used to provide inline meta data for the document. In HTML-based documents, the property name is used in the name
attribute of meta
elements, and the value of the property is used in the content
attribute.
The properties under “rel” may be used to describe relationships with whole documents. In HTML-based documents, the property name may be used in the rel
or rev
attributes of linking elements (link
and a
).
In addition to the properties listed under “rel”, all HTML 4 link types are available to documents using this profile.
The meta data properties available for a document 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. The document language may also have a default set of available properties which may be used in addition to those defined here. In the case that the default properties provided by the document language conflict with the properties defined in this profile, the default properties should take precedence.

would refer to a document which provides a graphical branding for a link to the current document. Due to potential complications with this link type modifier, authors are generally discouraged from using it except where necessary to direct legacy user agents to the appropriate information./
character and before any following ?
character, #
character, or end of the URI, whichever is first, should be the name of the relevant topic. The URI value should contain at least one /
character. For example, for the URI http://www.webdevout.net/tidings/category/web-development
, it is inferred that “web-development” is the topic of the resource collection.rev
attribute, indicating that the author of the current document is indifferent in regard to the content of the linked document or otherwise abstains from expressing an opinion toward it. For compatibility reasons, this link type must not be used with the rel
attribute in HTML-based languages.rev
attribute, indicating that the author of the current document disagrees with the content of the linked document. For compatibility reasons, this link type must not be used with the rel
attribute in HTML-based languages.rev
attribute, indicating that the author of the current document agrees with the content of the linked document. For compatibility reasons, this link type must not be used with the rel
attribute in HTML-based languages.
