British Catalogue of Music Classification

"The British Catalogue of Music Classification (BCM Classification) is a faceted classification that was commissioned from E. J. Coates by the Council of the British National Bibliography to organize the content of the British Catalogue of Music. The published schedule (1960) was considerably expanded by Patrick Mills of the British Library up until its use was abandoned in 1998. Entries in the catalogue were organized by BCM classmark from the catalogue's inception in 1957 until 1982.

Yosemite Decimal System

"The Yosemite Decimal System (YDS) is a three-part system used for rating the difficulty of walks, hikes, and climbs. It is primarily used by mountaineers in the United States and Canada. The Class 5 portion of the Class scale is primarily a rock climbing classification system, while the Classes 1-3 are used mainly in hiking and trail running. Originally the system was a single-part classification system. In recent years, Grade and Protection categories were added to the system. The new categories do not apply to every climb and usage varies widely.

Romanesque Art

"Throughout the 11th and 12th centuries there was a growing spirit of religious fervour in Europe. Groups of pilgrims embarked upon journeys to holy sites and the Crusades were organized to set the Holy Land free from the Muslims. At the same time, more and more devotees renounced the mundane world to retire into religious communities called monasteries. Soon monks gained great influence on all aspects of contemporary society.

AFEMS Glossary

"The Glossary presented in this part of the website has been compiled by AFEMS’s Technical Committee on the base of its practical experience and intends to provide an operative support to the Member of the Association dealing with the proper definition of technical words in the most common EU languages.
It is not a comprehensive instrument, because it doesn’t cover the full range of terms used in our industry and the term’s definitions could be subject in the time to further change and refinement. The Glossary doesn’t intend to provide any legal definition of the terms included."

Star Trek Spectral Classification

"Stars can generally be classified by their color. A purple star is always Class O, a yellow star is always Class G. However, there can be vast differences within each class. Most Class M stars are tiny and don't emit much light... however, many K- and G-type stars can evolve into red giants. That makes them Class M, but they are NOTHING like the tiny stars that make up the vast majority of Class M stars. Since most stars spend most of their lives on the Main Sequence, the descriptions on this page can be applied to the majority of stars.

Star Trek Nebula Classification

"A nebula is an interstellar cloud of dust, gas, and plasma, where star formation usually occurs. In the year 2400, the Federation introduced a new system to classify nebulae. The new system first assigns the nebula a letter designation based upon its general composition. If the nebula has any unusual quirks, it is assigned an additional number designation. For example, a Class F2 Nebula is a Dark Nebula that contains disruptive electromagnetic radiation."

Star Trek Planetary Classification

"A planet is a celestial body in orbit around a star or stellar remnants, that has sufficient mass for self-gravity and is nearly spherical in shape. A planet must not share its orbital region with other bodies of significant size (except for its own satellites), and must be below the threshold for thermonuclear fusion of
deuterium. If a celestial body meets those requirements, it is considered a planet; at that point, the planet is further classified by its atmosphere and surface conditions into one of twenty-two categories."

Glosario da Arte Contemporánea

"Este glosario naceu da necesidade de ampliar os repertorios terminográficos sobre arte contemporánea que incluísen o galego como lingua de traballo. Actualmente, a arte está a adquirir un gran pulo en Galicia, principalmente grazas á actividade de novos museos, galerías e salas de exposicións que amosan o traballo dos artistas máis novos ou innovadores do panorama internacional.
