Tezaurus.hr is a platform designed as a database for all dictionaries, used in various domains (within the digital humanities and beyond). This multilingual platform is intended for further expansion and development to meet the needs for controlled dictionaries within different communities. The main idea of the Tezaurus.hr platform is to gather and store all controlled dictionaries in one place and at the same time enable their use in different collections and in different institutions. On the other hand, any controlled dictionary developed within the platform can be used as a ‘standalone tool’ that can help anyone looking for appropriate terminology for material indexing purposes. The platform allows the integration of different metadata standards and dictionaries from different known sources, such as Getty Thesaurus, Geospatial Thesaurus, etc.
