lokaalnum

Lokaalnum is a term used in data management to describe a compact local numbering scheme intended to identify items within a defined locality. The concept is typically applied in contexts where data are processed within a limited geographic or organizational boundary and where global identifiers are impractical for routine local use. It is not part of a formal international standard and is used mainly in municipal, campus, or corporate IT discussions.

Design and structure: A lokaalnum usually encodes locality information in its most significant digits, followed by a serial component. Conventions often employ fixed-length numeric strings, with a locality code distinguishing districts, campuses, or departments. Some implementations include a check digit for error detection, and local authorities maintain allocation pools to avoid collisions.

Relation to global identifiers: Lokaalnum is designed to be interoperable with global systems through mappings that link lokaalnums to corresponding global IDs. Direct exposure of global IDs may be avoided for privacy or security, while mappings enable cross-boundary data integration when necessary.

Applications: The scheme is used in asset management, library catalogs, and inventory control within organizations or local governments. It supports offline operation since numbers are assigned locally, and it helps maintain contextual locality in data governance and reporting.

Advantages and limitations: Benefits include localized control and faster local queries. Limitations include fragmentation across localities, the overhead of maintaining mappings to global identifiers, and potential difficulties when merging datasets from multiple locales. Some practitioners prefer explicit global IDs to ensure universal interoperability.
