The "Corporate Bodies" vocabulary was developed by the National Documentation (EKT) to support the increased documentation needs of the content collected in its repository infrastructures. It is a bilingual, hierarchical vocabulary that aims to document and link current and past corporate body / organization names. The schema of the vocabulary is based on the madsrdf standard and in addition to the basic description elements (proposed name, identifying data, address elements, notes, related web pages) contains current hierarchical relationships (is part of, consists of) and past (was part of , consisted of). At the same time, it supports a series of historical relationships that describe the evolution of organizations over time (earlier and later name, merged with another entity and resulted in, resulted from the merge of, split into, resulted from the split of, absorbed, absorbed by). The vocabulary is constantly updated and enriched with additional terms in the context of its use.
