General Meta Data Profile, 1.3
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:
The top-level properties listed below, other than
rel, 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

- Information about content contained in the document or child documents whose exposure to certain audiences may produce ethical complications.
- A name of or identifier for an individual or group that participated in the formation of the document's content.
- A copyright statement for the document.
- A timestamp representing when the document was first created. The format for the timestamp is the same as the standardized HTML dates and times format.
- A brief summary of the document's content.
- A name of or identifier for a tool used to automatically generate source code in the document.
- A comma-separated list of topics covered by the document.
- A timestamp representing when the document was last modified. The format for the timestamp is the same as the standardized HTML dates and times format.
- A comma-separated list of identifiers that indicate some desired behavior for automated agents. Acceptable values are described in the Robots META tag specification.
- Information about content contained in the current document or child documents whose exposure to certain audiences may produce ethical complications.
- Information about an individual or group that participated in the formation of the document's content.
- A document whose topic is bounded by the broader scope of the current document.
- A document that contains public discussion about the current document.
- A document that provides a graphical branding for the current document.
- Information about a license describing legally acceptable use of the document.
- A document whose link was added to the current document by an unaffiliated source and whose topic has not been confirmed by the current document's author to have relevance with the current document.
- A document whose topic's broader scope bounds the current document.
- A document that is likely to be requested after the current document, although it may not necessarily be the next document in a structural sequence.
- This modifies an attached link type to relate to links made to the current document, rather than the current document itself. For example,
shortcut icon would refer to a document that 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.
- 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.
