Abstract : Web applications facilitate combining resources (linked data, web services, source code, documents, etc.) to create new ones. For a resource producer, choosing the appropriate license for a combined resource involves choosing a license compliant with all the licenses of combined resources and controlling the reusability of the resulting resource through the compatibility of its license. The risk is either, to choose a license too restrictive making the resource difficult to reuse, or to choose a not enough restrictive license that will not sufficiently protect the resource. Finding the right trade-off between compliance and compatibility is a difficult process. An automatic classification over licenses protecting resources would facilitate this task. Our research question is: given a license li, how to automatically position li over a set of licenses in terms of compatibility and compliance? We propose CaLi, a lattice-based model to classify licenses. CaLi classifications are able to answer questions like, " what are the licenses with which li is compliant? " and " what are the licenses with which li is compatible? ". We show the usability of a CaLi classification through a prototype of a license-based search engine for the Web of Data. Our work is a step forward to facilitate and encourage the reuse of license compliant resources in the Web.
