0255arvoina

0255arvoina is a Finnish term that literally translates as “values 0255” and is used in specific technical contexts within Finnish data management and software development. The designation originates from a legacy coding convention that was introduced in the 1990s to represent a subset of numeric values used in legacy financial and tax systems. In these systems, the number 0255 was adopted as a unique code to identify a particular category of values, such as tax rates, fiscal brackets, or accounting entries.

In contemporary usage, 0255arvoina typically appears as a field label or parameter name in data exchange formats, particularly in XML or CSV files exchanged between public sector agencies and private sector information technology solutions. The label signals to developers and data analysts that the associated numeric values belong to the predefined 0255 set, which follows a strict enumeration of allowable values that must be validated against a master reference table.

Although the original coding system was superseded by newer open‑standards specifications in the early 2010s, 0255arvoina remains in use in some legacy infrastructure, especially within archival repositories and historical data sets that preserve earlier formats for compliance and forensic purposes. The term is documented in a small number of technical manuals and legacy system reference guides, and it appears in archival metadata for several national datasets, including those maintained by the Finnish Tax Administration and the Institute for National Innovation Studies.
