 Extension - Wikipedia, the free encyclopedia
In general semantics, extension is a process that, as in this mathematical example, starts with unique individuals, and gives them unique names, e.g., I, II, III, etc., or 1, 2, 3, etc. The next step if needed generalizes or passes beyond extension to infinite-valued higher-order abstractions like 'numbers', and so on.
In physiology, extension is one of the movements of a joint such as the knee.
Hair extensions are strands of human hair placed onto a persons hair in order to elongate or thicken existing hair.

 Extension (semantics) - InfoSearchPoint.com   (Site not responding. Last check: 2007-10-20)
In philosophical semantics or philosophy of language, the extension of a word, phrase, or concept is the set of things it extends to, or applies to.
For example, the extension of a function is a set of ordered pairs that pair up the arguments and values of the function; in other words, the function's graph.
The extension of an object in abstract algebra, such as a group, is the underlying set of the object.The extension of a set is, of course, the set itself.

For example, C (the field of complex numbers) is an extension of R (the field of real numbers), and R is itself an extension of Q (the field of rational numbers).
The extension is said to be finite or infinite according as the degree is finite or infinite.
Extension also plays an important part in the philosophy of Spinoza, who claims that substance (that which has extension) can only be limited by substance of the same sort, i.e.

 RFC 2774 (rfc2774) - An HTTP Extension Framework
Extension Declarations An extension declaration can be used to indicate that an extension has been applied to a message and possibly to reserve a part of the header namespace identified by a header field prefix (see 3.1).
Examples of extension declarations are "http://www.company.com/extension"; ns=11 "Range" An agent MAY use the decl-extensions mechanism to include optional extension declaration parameters but cannot assume these parameters to be recognized by the recipient.
The extension definition may be made available in different representations ranging from o a human-readable specification defining the extension semantics (see for example [7]), o downloadable code which implements the semantics defined by the extension, o a formal interface description provided by the extension, to o a machine-readable specification defining the extension semantics.

The certificate extensions are subject directory attributes, certificate policies, key usage, a private extension for storage of biometric data and a private extension for storage of statements related to Qualified Certificates.
A typical statement suitable for inclusion in this extension MAY be a statement by the issuer that the certificate is issued as a Qualified Certificate in accordance with a particular legal system (as discussed in Section 2.2).

But there are other possibilities than language extensions that could be interesting, such as some form of static analysis, program optimisation or performing type-checking for stronger properties.
This can either be an extension to the language and type system, or it could be some other kind of static analysis or program optimisation.
Semantics in this context is the study of the principles and formal (mathematical) techniques for the description of programming languages.

 Conservative Extension in Structural Operational Semantics   (Site not responding. Last check: 2007-10-20)
Over and over again, process calculi such as CCS, CSP, and ACP have been extended with new features, and the Transition System Specifications (TSSs) that provide the operational semantics for these process algebras were extended with transition rules to describe these features.
A question that arises naturally is whether or not the original and the extended TSS induce the same transitions in the original domain.
Usually it is desirable that an extension is operationally conservative, meaning that the provable transitions for an original term are the same both in the original and in the extended TSS.

Issue 220: Document interface extension semantics from Mark Nottingham on 2004-07-05 (www-ws-desc@w3.org from July 2004)
Namely, information about interface extension is spread throughout the draft, making it difficult to get a good picture of how it works.
I think there are a couple of directions we could go to clarify this; if I can get a sense of what other people think, I'll be glad to make a concrete proposal.
