IUPAC Nomenclature of Organic Chemistry

"Chemical nomenclature is used to identify a chemical species by means of written or spoken words and enables a common language for communication amongst chemists. Nomenclature for chemical compounds additionally contains an explicit or implied relationship to the structure of the compound, in order that the reader or listener can deduce the structure from the name. This purpose requires a system of principles and rules, the application of which gives rise to a systematic nomenclature.

Multilingual Dictionary of Cataloguing Terms and Concepts

"The Multilingual dictionary of cataloguing terms and concepts contains definitions for many terms and concepts used by the library cataloguing community. Terms and definitions are available in English and a variety of other languages.
The MulDiCat project was begun by Monika Muennich in 1998 for IFLA's Cataloguing Section. It was stored in a proprietary database developed by Bernard Eversberg in 2003. It has now re-emerged in part as a Word table and as a SKOS file on the new IFLA Namespace.

Multiple services can be derived from this terminology, e.g. a classical glossary and a math dictionary."

Resource Type Vocabulary

"The Resource Type vocabulary defines concepts to identify the genre of a resource. Such resources, like publications, research data, audio and video objects, are typically deposited in institutional and thematic repositories or published in ejournals. This vocabulary supports a hierarchical model that relates narrower and broader concepts. Multilingual labels regard regional distinctions in language and term. Concepts of this vocabulary are mapped with terms and concepts of similar vocabularies and dictionaries.

TNM Classification of Malignant Tumors

"The classification of cancer by anatomic disease extent, i.e. stage, is the major determinant of appropriate treatment and prognosis. Stage is an increasingly important component of cancer surveillance and cancer control and an endpoint for the evaluation of the population-based screening and early detection efforts. The UICC has published the UICC TNM classification of malignant tumours for over 50 years. The UICC TNM classification is the internationally accepted standard for cancer staging.

CIDOC Conceptual Reference Model

"The CIDOC Conceptual Reference Model (CRM) provides definitions and a formal structure for describing the implicit and explicit concepts and relationships used in cultural heritage documentation. The CIDOC CRM is intended to promote a shared understanding of cultural heritage information by providing a common and extensible semantic framework that any cultural heritage information can be mapped to. It is intended to be a common language for domain experts and implementers to formulate requirements for information systems and to serve as a guide for good practice of conceptual modelling.

SilvaVoc Terminology
