Welcome to the TSN-Project documentation
TSNs (Territorial Statistical Nomenclatures) are geographic divisions built by Statistical Institutes, usually deriving from electoral or administrative structure. TSNs geographic divisions change over time.
The TSN and TSN-Change Ontologies (Territorial Statistical Nomenclature Ontology) enable the description of any geographic divisions for statistics into the Web of Linked Data and, above all, rich descriptions of territorial changes from one geographic divisions version to another.
Through times, all over the world, the areas (portions of space on earth) delimited by or, under the control of human groups (e.g., administrative or electoral areas) are subject to change : their names, belonging or boundaries change for some political or administrative reasons. Likewise, the Territorial Statistical Nomenclatures (TSNs) that are sets of artifact areas built by Statistical Institutes, and usually deriving from electoral or administrative structures, also change over time and at several division levels (e.g., regions, districts, sub-districts). These changes in TSNs are an obstacle to maintain socio-economic data comparability over time. Since most of the time, they lead to broken time-series and are source of misinterpretations of statistics when not properly documented.
This phenomenon is very frequent in Europe (for instance in France, in 2016, administrative regions have been merged into greater regions) or in the U.S.A. (through a well-known process called gerrymandering).
We propose the following representation of TSN changes on the Linked Open Data Web:
