Then there are specific ones, ranking categories and topics in a hierarchical manner based on the relationship existing among them with reference to a single common trait, property or use which, put together, form various components of a specific subject area. Many such specialised classifications are created by librarians and documentalists struggling with their growing collections on subjects which are too specialised or too heterogeneous in scope to the point of defying the breakdown of traditional classifications by scientific disciplines or categories. I have revised, enlarged and updated this classification several times in the course of the years. Several general criteria have been applied as consistently as possible to make this classification system workable. In order to follow a logical sequence of concepts in the area of human rights I used as the basis the structure of the Universal Declaration of Human Rights and extended its core theme by ramifications into the complementary spheres and areas of applications.
Violations are, consequently, listed as subdivisions.
The structure of the table is constructed in such a way that additional categories and subdivisions are possible at any level, as required. An extract of the classification table will best illustrate its format. The classification system is available on this site .
