META element

<World-Wide Web> An element, with tag name of "META", expressing meta-data about a given HTML document. HTML standards do not require that documents have META elements; but if META elements occur, they must be inside the document's HEAD element. The META element can be used to identify properties of a document (e.g., author, expiration date, a list of key words, etc.) and assign values to those properties, typically by specifying a NAME attribute (to name the property) and a CONTENT attribute (to assign a value for that property). The HTML 4 specification doesn't standardise particular NAME properties or CONTENT values; but it is conventional to use a "Description" property to convey a short summary of the document, and a "Keywords" property to provide a list of keywords relevant to the document, as in: <META NAME="Description" CONTENT="Information from around the world on kumquat farming techniques and current kumquat production and consumption data"> <META NAME="Keywords" CONTENT="kumquat, Fortunella"> META elements with HTTP-EQUIV and CONTENT attributes can simulate the effect of HTTP header lines, as in: <META HTTP-EQUIV="Expires" CONTENT="Tue, 22 Mar 2000 16:18:35 GMT"> <META HTTP-EQUIV="Refresh" CONTENT="10; URL=http://foldoc.org/"> Other properties may be application-specific. For example, the {Robots Exclusion (http://info.webcrawler.com/mak/projects/robots/norobots.html)}. standard uses the "robots" property for asserting that the given document should not be indexed by robots, nor should links in it be followed: <META NAME="robots" CONTENT="noindex,follow"> (2001-02-07)

Meta element

Meta elements are tags used in HTML and XHTML documents to provide structured metadata about a Web page. They are part of a web page's head section. Multiple Meta elements with different attributes can be used on the same page. Meta elements can be used to specify page description, keywords and any other metadata not provided through the other head elements and attributes.

The meta element has two uses: either to emulate the use of an HTTP response header field, or to embed additional metadata within the HTML document.

With HTML up to and including HTML 4.01 and XHTML, there were four valid attributes: content, http-equiv, name and scheme. Under HTML 5, charset has been added and scheme has been removed. http-equiv is used to emulate an HTTP header, and name to embed metadata. The value of the statement, in either case, is contained in the content attribute, which is the only required attribute unless charset is given. charset is used to indicate the character set of the document, and is available in HTML5.

Such elements must be placed as tags in the head section of an HTML or XHTML document.
