Home » Workgroups


Participants in the workgroups are industry actors that share a genuine belief in a common digital language and want to be a part of moving the industry into the future with standards-based data templates and shared contexts.

The Define workgroups will discuss and agree on content for data dictionaries as well as help new users by sharing knowledge and assisting them in onboarding to Define and the development of the global common digital language.

As a participant in the workgroups, you can ensure that your input will be considered and reflected in the development of the Define tool to the best interest of the construction industry. All users of Define will have the opportunity to take part in one or more workgroups.

Content Modeling Workgroup

The Content Modeling Workgroup focuses on the structure of data dictionaries and how it can be used to resolve practical use cases.  The workgroup is a forum of experts from different organizations with varying backgrounds that through agreement between members will develop rules, recommendations and best practices for working with and within data dictionaries.

Any considerations of the workgroup will take into account and balance both the business needs of the industry and the provisions of the relevant CEN/TC 442 and ISO/TC 59/SC 13 standards.


Establish a common industry framework for modeling content in data dictionaries, that will ensure:

  • Data dictionaries can be interconnected, providing efficient sharing and reusing of content between each other.
  • Consistent outcomes for content creators, clear application for end users and common expectations for both sides.
