IPTC NewsCodes

"For the news industry - but also far beyond - it is a strict requirement being able to assert something about the content of a news item, to apply so called metadata. This could be achieved either by free-text human language (e.g. by a headline or a caption) or by codes, NewsCodes. Codes have the advantage that they can be easily shared among users and as each code requires an explicit and comprehensive definition not only the codes but also their semantics can be shared among users.

Open Family Services Directory

"The Open Family Services subject vocabulary provides a way of categorising family services within the Open Family Services Directory (formerly DfE Family Information Directory). The 'Guidance' tab describes how the list is used and links to guidance and complementary controlled vocabulary files. The 'Formats' makes the list available in a variety of formats including its native ZThes XML format."

The Bliss Bibliographic Classification

"The Bibliographic Classification (BC2 or Bliss) is the leading example of a fully faceted classification scheme. It provides a detailed classification for use in libraries and information services of all kinds, having a broad and detailed structure and order. The vocabulary in each class is comprehensive and complemented by an exceptionally brief faceted notation considering the detail available, providing indexing to any depth the classifier wishes.

Derwent Drug File Thesaurus

"The Thesaurus contains all searchable keywords except the newest drug names and novel concepts that have arisen since publication. The Thesaurus is laid out in two columns; the left column contains the look-up term and the right column either contains the higher terms of a keyword, the generic name of a proprietary drug name, or refers the seacher to the correct term or alternative terms to use. Higher terms associated with specific keywords are indicated by the abbreviation h.t. and are found in the right column of the Thesaurus.

Derwent Biotechnology Abstracts Thesaurus

"Generic terms (Higher Terms) associated with specific keywords are indicated by the use of the abbreviation 'h.t.'. This means that whenever the specific term appears in the file, the corresponding Higher Term(s) will also appear and can be searched instead of the specific keyword if a broader search is desired. The abbreviation 's.a.' (see also) is used to indicate a related term which may also be worth considering in a search. Some terms have been altered since the start of the database and this is indicated by the use of the word 'was'.

International Classification of Headache Disorders

"This classification is hierarchical and you must decide how detailed you want to make your diagnosis. This can range from the first-digit level to the fourth. First one gets a rough idea about which group the patient belongs to. Is it for example 1. Migraine or 2. Tension-type headache or 3. Cluster headache and other trigeminal autonomic cephalalgias? Then one obtains information allowing a more detailed diagnosis. The desired detail depends on the purpose.
