HURIDOCS has developed 48 Micro-thesauri to be used in conjunction with the various formats - they are published in the document Micro-thesauri: A Tool for Documenting Human Rights Violations (usually referred to as Micro-thesauri). While these Micro-thesauri are intended primarily for use with the Events Standard Formats and their computer implementations such as WinEvsys, they are also relevant for other applications such as bibliographic information recording. The first 17 Micro-thesauri in particular can be widely used beyond documentation of human rights violations. The contents of the lists are based on new developments, earlier work by HURIDOCS, input from members of the HURIDOCS network, and work by other organisations including the United Nations, the International Labour Organisation, the International Refugee Documentation Network and the Minority Rights Group. In particular, HURIDOCS has adopted many standards promoted by the International Organisation for Standardisation (ISO). ISO at present includes the national standards bodies of some 90 countries and is recognised as the specialised international agency for standardisation. It has developed a wide range of standards implemented world-wide. Many of the Events Micro-thesauri, however, have evolved from the use of grassroots NGOs. HURIDOCS Task Forces have facilitated the exchange of ideas among various information practitioners from all over the world, leading to agreements on standardised terminologies. 42
