What exactly is a Knowledge Organization System, and what is it good for?
• A Knowledge Organization System (KOS) is a set of elements, often structured and controlled, which can be used for describing (indexing) objects, browsing collections, etc (see SKOS cases). Typical examples of KOS are thesauri, classification schemes, subject heading lists, taxonomies… KOSs are common in cultural heritage institutions (libraries, museums) or in any scientific discipline, such as biology, which has a specific interest in naming and classifying.
