The vocabulary «EKT Subjects across Scientific Disciplines» is developed by National Documentation Centre (EKT), using “up to date technologies”, in compliance with current developments in metadata standards, semantic web principles and interoperability terms. The vocabulary comprises 453 unique bilingual subject terms covering the main areas of Science, Technology & Development. The terms are classified by hierarchical relationships (broader / narrower) while semantic link relations to external open resources, are attributed. The enrichment with new terms and links is ongoing.
