Development of guidelines for publishing statistical data as linked open data

(Submission #242)


Polish official statistics possesses a vast amount of statistical data dispersed among different databases and disseminated using various publication methods. While there is a significant increase in openness of the data, there is still a lot of work to be done in terms of integrating different data sources. That is why the Central Statistical Office of Poland decided to look into the linked open data technology. An ongoing project has resulted in an inventory of databases and data sources currently published by official statistics and is investigating linked data technologies in order to prepare a “cook-book” for a linked open data implementation.

Multiple data sources published by official statistics have been identified, described with metadata and assessed in terms of their openness. At the same time, units of territorial division of the country that are used for statistical data dissemination have been catalogued and harmonized for years 2002-2016. Guidelines for generalization of the units’ geometries are being created along with an attempt to identify minor geometry changes based on the harmonized / generalized data. Also, a system of unique identifiers for these spatial units is being developed, taking into account the NUTS 2016 revision.

Finally, linked open data technologies are being explored in order to find a feasible implementation method. Three major databases (Local Data Bank, STRATEG system and Demography database) have been chosen for a pilot linked open data implementation. From each database a fragment describing similar data has been chosen for tests using linked data tools. At the same time, linked open data technologies for geographical data as linked open data are being explored in order to design a method for publishing the harmonized geodata.

The results of the project will provide a foundation for a full-on linked open data implementation by official statistics in the near future.
