ABSTRACT
Creating and sharing more data within the value chain during the whole life cycle of a building is regarded as one of the key elements towards the digitalization of the construction sector. Although many stakeholders are willing to share data, they fear the potential misuse and loss of control over their data. The concepts behind data sovereignty and the legal value remains vague in political as well as scientific discussions. The paper identifies the dimensions of data sovereignty and links them to the legal concepts of data governance including technical and organizational standards in construction law. Based on these findings a definition of data sovereignty is proposed. Thereinafter, stakeholder roles and interests are examined and legally categorized by transferring concepts of data and IP law. Finally, legal and organizational measures are derived for establishing and documenting data sovereignty as part of the construction process.
