Get access to construction Data Dictionaries

Ensure free flow of high-quality data across the construction industry

To help organisations make their machine-readable and standardised data available to all users, data dictionaries provide ready-to-use construction object data templates.

Data dictionaries are developed either on a national level to cover the needs of a specific market, or they are established by industry organisations and other construction actors to improve the information exchange within a sector. Users can currently choose to get access to a UK Data Dictionary, Norwegian Data Dictionary, Portuguese Data Dictionary and European Data Dictionary.

Using the published data templates in practice

Data dictionaries enable construction stakeholders to start using a common language which allows all users to get the same information in an industry-agreed and structured format. This will allow them to take substantial leaps towards standards-based management of their data, thus ensuring interoperability and repeatability. By implementing a standardised data structure, your data can be shared and reused everywhere.

Define workgroups

For the development of data templates on a national or organisational level, workgroups have been established within the Define community. Their tasks include taking national or organisational needs and regulations into account when developing data templates.

Currently, workgroups are being established by industry actors in Norway and UK to continue the work on the data dictionaries. In Denmark this work is driven by Molio, in The Czech Republic by CAS, and by CEI-Bois for the European woodworking industry.
