"TRANSFAC® provides data on eukaryotic transcription factors, their experimentally-proven binding sites, consensus binding sequences (positional weight matrices) and regulated genes. 5 superclasses, 33 classes, 76 families, 91 subfamilies."
"The Tree of Life Web Project is a collection of information about biodiversity compiled collaboratively by hundreds of expert and amateur contributors. Its goal is to contain a page with pictures, text, and other information for every species and for each group of organisms, living or extinct. Connections between Tree of Life web pages follow phylogenetic branching patterns between groups of organisms, so visitors can browse the hierarchy of life and learn about phylogeny and evolution as well as the characteristics of individual groups."
"Organisms are classified in a hierarchical tree structure. Our taxonomy database contains every node (taxon) of the tree. UniProtKB taxonomy data is manually curated: next to manually verified organism names, we provide a selection of external links, organism strains and viral host information."
"Here are mineral lists (IMA approved mineral names and varieties names) sorted either alphabetically or arranged systematically. As every science, mineralogy is changing: new analysis often modify formulas and other datas; new minerals are discovered; others are discredited. So, consider these lists as dynamic and subject to change and error. Comments, corrections and additions are welcome. It follows Strunz classification schemes (Mineralogical Tables, VIIIth edition) and has been modified according to the systematic numbers published in the 'Lapis Mineralienverzeichnis'.
"481 terms, 132 relations between terms, 120 non-preferred terms."
"The terms in the Joint Thesaurus are listed alphabetically. For each alphabetical entry, a 'word block', containing the terms associated with this particular entry, is displayed. In the word block, terms that have a hierarchical relationship to the entry are identified by the symbols BT for Broader Term, and NT for Narrower Term; a term with an affinitive relationship is identified by RT, for Related Term; terms with a preferential relationship are identified by USE or SEE, and UF for Used For, and SF for Seen For.
"The main aim in producing this reference work is to try to standardise the terminology in the field of astronomy for the purposes of aiding unambiguous library cataloguing and more precise recall of data from computer databases. The thesaurus is intended for use by astronomy librarians and scientists. Its compilation was originally requested during a meeting of Commission 5 (Documentation) of the International Astronomical Union at the New Delhi General Assembly of the IAU in 1984.
"This thesaurus functions as a means for indexing articles, photos, and web pages on some of the basic identifying characteristics of herbs. It is designed for the hobbyist or recreational gardener rather than scientist or medical reference. The preferred terminology is that of a home gardener rather than a herbalists or botanists since they are the targeted end-user. (...) This mini-thesaurus contains preferred terms selected based on common usage, and the cross-references are made from the non-preferred terms. Scope notes have been added where necessary.
"The Hierarchical Listing With Definitions contains all subject terms and USE cross references currently approved for use, and displays the full hierarchical structure for each term along with a definition when available. In addition, the listing has been developed to serve as an orthographic authority for upper/lowercase forms of all terms and cross references. The term-added date, displayed for all terms added after April 1988, is also given.
"The ASFA Thesaurus is an indexing and searching tool. It contains the subject descriptors used to index the records which are contained in the Aquatic Sciences and Fisheries Abstracts (ASFA) bibliographic database."
