Open data refers to the concept of making data freely available for all to use, enhancing its value when shared and connected within an ecosystem of partners and clients. It is not about universal access but rather about shareability while maintaining security principles.

Open data is crucial for digital twins, which are digital representations supporting asset management and construction. The data must be as open as possible to create maximum value for everyone. Additionally, open data is central to digital transformation initiatives, improving cost, value, and performance by enabling better insights and decision-making. It involves data that is not tied to specific software solutions, allowing for broader accessibility and usability.
