The Meta-Meta Page
Metatags and Other <HEAD>aches
At the beginning of most HTML pages is a <Head> section, hidden from the user but highly visible to browsers and other bits of Internet machinery such as search engine spiders and caching systems. It's full of meta tags and other sorely-abused bits of HTML.
Meta Searchers
Metasearchers submit your query to several search engines
simultaneously; some will collate the results before returning
them to you, e.g.
The MetaCrawler,
an original, true metasearcher.
Some people abuse the term 'metasearcher' to simply present lists of
search engines, or several search forms on one page ('all-in-one').
Tagging
It is possible for you to control how your page is indexed by using the
META tag to specify additional keywords to index, and a short abstract.
This tag can be used to augment documents with information that is not
normally displayed by browsers.
META Refresh (Client Pull)
An HTML document can be made to automatically replace itself with
another, after a specified period of time. This one shows you how.
The HTML META Tag
HTML construct that allows specification of items above and beyond
those embedded in the HTML/HTTP system itself, e.g. search keywords.
Encyclopedia entry for "Meta"
An HTML tag used in the Head area of a document to
specify further information about the document, either for the
local server, or for a remote browser.
The META element is used within the Head element to embed document
meta-information not defined by other HTML elements. Such information
can be extracted by servers/clients for use in identifying,
indexing, and cataloging specialized document meta-information.
In addition, HTTP servers can read the contents of the document
head to generate response headers corresponding to any elements
defining a value for the attribute HTTP-EQUIV. This provides document
authors with a mechanism for identifying information that should be
included in the response headers of an HTTP request.
Meta Lists
"Lists of Lists" - the web is saturated with them.
Just search for "meta lists"..
Most of them are of marginal value, unless they offer some guidance or
ratings - the user may end up traversing endless links without ever
actually finding anything useful.
Here's a couple of useful ones:
Platform for Internet Content Selection
PICS is an infrastructure for associating labels with Internet content.
It was originally designed to help parents and teachers control what
children access on the Internet, but it also facilitates other uses for
labels, including code signing, privacy, and intellectual property
rights management.
