Polythematic Structured Subject Heading System (PSH) is an example of knowledge organisation system (KOS) which is intended for indexing and searching documents by subject. Traditionally, the subject indexing has been the responsibility of professionals – librarians. Nowadays, this type of intellectual process is also made available to general public.

In 2009 PSH was published in Simple Knowledge Organisation System (SKOS) format under Creative Commons (CC) licencing terms. SKOS is designed to represent traditional knowledge organisation systems. It provides means for expressing standard relationships that can be found in most thesauri or subject heading systems. SKOS is defined using RDF Schema and expressed in RDF data model.

There is a possibility to display tags from PSH in Dublin Core and CommonTag formats in PSH section on the National technical library´s websites. Metadata tags can be embedded in (X)HTML document to achieve its semantic description. If available, there are also links reffering to similar concepts found in Library of Congress Subject Headings or on DBpedia.

Currently PSH is not only a tool for bibliographic records selecting but its potential is also developed in the area of indexing and searching web documents.
