RFC 3986 URI Generic Syntax January 2005 Table of Contents 1. RFC 3986 URI Generic Syntax January 2005 6. RFC 3986 URI Generic Syntax January 2005 1. A Uniform Resource Identifier (URI) provides a simple and extensible means for identifying a resource. 1.1. URIs are characterized as follows: Uniform Uniformity provides several benefits. 1.1.1. Each URI begins with a scheme name, as defined in Section 3.1, that refers to a specification for assigning identifiers within that scheme.

Metamodeling. Example of a Geologic map information meta-model, with four types of meta-objects, and their self-references.[1] Metamodeling or meta-modeling is the analysis, construction and development of the frames, rules, constraints, models and theories applicable and useful for modeling a predefined class of problems.


As its name implies, this concept applies the notions of meta- and modeling in software engineering and systems engineering. Overview[edit] Common uses for metamodels are: As a schema for semantic data that needs to be exchanged or storedAs a language that supports a particular method or processAs a language to express additional semantics of existing informationAs a mechanism to create tools that work with a broad class of models at run timeAs a schema for modeling and automatically exploring sentences of a language with applications to automated test synthesis.

Vannevar Bush à son bureau pendant la Seconde Guerre mondiale Signature Vannevar Bush, né le à Everett dans le Massachusetts et mort le à Belmont dans le Massachusetts, est un ingénieur américain, conseiller scientifique du président Roosevelt et chercheur au Massachusetts Institute of Technology (MIT). Il est principalement connu en tant que maître d’œuvre de la recherche scientifique des États-Unis lors de la Seconde Guerre mondiale et comme l'un des inspirateurs d'Internet.

As We May Think

Vannevar Bush has coordinated the activities of some six thousand leading American scientists in the application of science to warfare. In this significant article he holds up an incentive for scientists when the fighting has ceased. He urges that men of science should then turn to the massive task of making more accessible our bewildering store of knowledge.

For years inventions have extended man's physical powers rather than the powers of his mind. Trip hammers that multiply the fists, microscopes that sharpen the eye, and engines of destruction and detection are new results, but not the end results, of modern science. This has not been a scientist's war; it has been a war in which all have had a part. For the biologists, and particularly for the medical scientists, there can be little indecision, for their war has hardly required them to leave the old paths.

History of the graphical user interface

There have been important technological achievements, and enhancements to the general interaction in small steps over previous systems. There have been a few significant breakthroughs in terms of use, but the same organizational metaphors and interaction idioms are still in use. Although many GUI operating systems are controlled by using a mouse, the keyboard can also be used with keyboard shortcuts or arrow keys. The interface developments described, below, have been summarized and omit many details in the interest of brevity. RFC 1855 - Netiquette Guidelines. [Docs] [txt|pdf] [draft-ietf-run-ne...]
