**Tags**: #MemberData #Transparency > [!info] > This information is shared as part of Decombine's commitment to [[Open Core]] practices. ## What is a Data Model? Decombine data management is engineered to be consistent across its services, processes, and products. This allows us to tell Members *exactly* what data is required to perform specific actions or use specific services. We open source all of our data models so that Members can inspect, extend, and customize how they or their organizations use Decombine services. Data models are developed using the same open source tooling used in smart legal contracts: [Concerto (accordproject.org)](https://concerto.accordproject.org/). After a model is developed, is it compiled and used directly in both our services and contracts, offering Members a trustworthy and consistent experience. ### Data Model Licenses All Decombine data models are licensed as Apache Version 2. ### Data Model Library The Decombine Data Model Library is currently under active development. It will soon be publicly released.
