According to Statistics Estonia’s strategy our goal is to produce high quality statistics with as low administrative burden and as high efficiency as possible. For achieving this, it is essential to have metadata driven statistical production process. At the beginning of 2018 Statistics Estonia (SE) started piloting Colectica software in search for a new metainformation system. Our goal was to test as much functionality as possible and to deliver the pilot report to the management. In the early days of 2019 it was decided that Colectica is the suitable software for implementing DDI standard in SE. Currently we are using metadata management system that is based on Neuchâtel model. The main reason for choosing DDI is the lifecycle model that enables to version and reuse different metadata objects and monitor data lineage. SE has decided to start the implementation of DDI step-by-step. The implementation process is divided into sub-projects. The first sub-project is managing statistical classifications in Colectica and developing website view through Colectica portal. The statistical classifications project began in April 2019 and the new classifications webpage should be live at the beginning of 2020.
