Use of universal address to ensure high-quality data

The article describes how to ensure high quality of data previously processed in silos, i.e. separate databases and central registers. The concept of using a universal address was created in Poland in 2017, it was tested in practice and recommended for use in the annex to Resolution No. 28 of the Council of Ministers of February 18, 2021 on the Data Opening Program for the years 2021-2027 (Monitor Polski 2021, item 290). It is based on a specific complex data - created automatically and also automatically used, built from legally authorized codes - the so-called universal address. It is appropriate for solutions used in Poland because it is based on codes created by the Central Statistical Office and data structures of the Central Office of Geodesy and Cartography. It seems, however, that the concept is universal and could also be used in other countries and places where silos - not having a direct connection with each other – contain theoretically the same data provided with specifically defined identifiers. The practical usefulness of the described solution justifies an attempt to popularize it more widely and use it in various forms. The purpose of this article is to present this concept and to discuss it.
