The ESS Statistical Production Reference Architecture (SPRA) provides a modelling of the to-be state architecture of ESS information systems based on various key artefacts of the ESS EA Reference Framework.

The SPRA uses the guidance from the ESS EARF to model aspects of statistical production believed to be crucial for realizing the ESS modernisation and to facilitate the sharing of solutions and services within the ESS.

The role of the SPRA in the EARF is depicted in the figure below.
