Nimikkeistöihin

Nimikkeistö on termi used in Finnish information management to refer to a coordinated set of standardized labels, designations, or codes used to describe items, subjects, products, or processes within a particular domain. Nimikkeistöihin denotes the items or concepts that belong to a given nomenclature system, and the illative plural form is commonly used in technical and administrative texts to indicate inclusion in these systems.

Nimikkeistöt typically consist of terms or codes arranged to support consistent indexing, retrieval, and data exchange. They may be hierarchical or flat, and often include preferred terms, synonyms, and explicit relationships such as broader and narrower concepts. They can be language-specific, multilingual, or domain-specific, and are usually maintained by a standards body, a government ministry, a library, an archive, or a professional association.

In practice, nimikkeistöjä are used in libraries for subject indexing, in archives and museums for cataloging, in procurement and product data management in industry, and in public administration for classification and statistics. They help ensure that the same item can be found and compared across different databases and systems, enabling interoperability and clearer communication between organizations.

Maintenance of nimikkeistö involves periodic updates, versioning, and crosswalks between versions to map terms from older nomenclatures to newer ones. Changes are typically coordinated by the responsible body, with documentation that supports data migration and compatibility. See also: classification systems, controlled vocabularies, thesauri.
