DALICC Vocabulary Documentation


DALICC stands for Data License Clearance Center. It is a software framework that supports application developers, legal experts and sales managers in the legally secure reutilization of third party digital sources such as data, content or software.

As modern IT applications increasingly retrieve, store and process data from a variety of sources, questions about the compatibility of licenses and the application`s compliance with existing law may occur. Issues of rights clearance are especially relevant in the creation of derivative works compiled from multiple data sources. Clearing and negotiating rights issues is a time-consuming, complex and error-prone task.

The DALICC framework supports the automated clearance of rights, thus helping to detect licensing conflicts and significantly reducing the costs of rights clearance in the creation of derivative works.

DALICC Information Model

DALICC Information Model

The DALICC Information Model as depicted in Figure 1 consists of two components.

The first component makes a reference to the ODRL information model to express permissions, duties and prohibitions stated in a license. It uses vocabularies from ODRL, CCRel and particular extensions to describe licenses for machine processing in a legally valid manner. In this respect a license can be understood as a policy that defines specific actions as permissions, duties or prohibitions.

The second component is the so-called Dependency Graph. This graph expresses the valid relationships between various actions defined in a license.The graph currently consists of three basic relationships: “included in”, “implies” and “contradicts”. The graph is used to check the consistency of the license itself and to detect potential conflicts arising from contradicting actions defined in two or more licenses.
