  4. 4. Introduction & Problem Statement DALICC stands for Data Licenses Clearance Center. The project‘s aim is to develop a software framework that significantly reduces the costs of license clearance in the creation of derivative (data) works. Problem Statement • The reuse of data, software or content is often accompanied with legal uncertainty with respect to intellectual property rights and privacy issues. • Rights clearance is costly. It requires expert knowledge, is error prone and time- consuming. • Easing the effort to clear rights increases productivity and stimulates the reuse of data. Partners: • UAS St. Pölten (Lead) • Vienna University of Economics & Business • University of Innsbruck • Höhne, In der Maur & Partner Rechtsanwälte OG • Semantic Web Company GmbH Runtime: 01.11.2016 – 30.10.2018 Funding Line: Austrian Research Promotion Agency – Future ICT

  6. 6. Usage Scenarios Scenario A: Alice chooses a license • Alice already knows which license she wants to apply to her work (i.e. CC-BY). She consults DALICC and retrieves the relevant resources (i.e. URI) Scenario B: Alice creates a license • Alice knows her conditions but does not exactly know which license suits her demands. She consults DALICC and creates a license through a guided dialogue. • DALICC checks whether the license is a custom license or a standard license. And provides the necessary reference to the license (i.e. URI etc.) • Alice can decide whether to contribute the license to the DALICC library (as linked open data) or keep it to herself. Scenario C: Alice checks license compatibility • Alice selects all licenses relevant to her work. • DALICC provides Alice with a compatibility report that also points her to conflicting terms.

Data Set N License N License {A … N} Derivative Work Data Set … License … Data Set B License B Data Set A License A License Composer License Annotator License Library DALICC Framework License Negotiator consults tags audits proposes • Compatibility • Conflict Detection • Conflict Resolution Functionalities of the DALICC Framework Functional Components: • License Composer: Lets you create customized licenses • License Library: Lets you choose from a set of standard licenses • License Annotator: Provides you with a machine-readable and human-readable version of your license • License Negotiator: Checks compatibility, detects conflicts and supports conflict resolution
  8. 8. Rights Clearance – Methodological Approach 1. Step: Formal Semantics & REL Evaluation • Analyse license terms for semantic equivalence / similarity / ambiguity (i.e. distribution) • Evaluate semantic expressivity of RELs (espec. ODRL) to represent license terms • Extend existing RELs for copyright purposes (DALICC vocabulary) 2. Step: License Representation • Represent licenses in RDF using ODRL + extensions • Contribute to W3C Permissions & Obligations Group 3. Step: Rights Clearance • Create rules to reason over RDF statements to … calculate similarity of licenses … detect conflicts between licenses … provide hints to conflict resolution 4. Step: Data Provision & Publishing • Provide API to integrate „DALICC as a service“ • Provide endpoints to retrieve (linked) open data from DALICC (i.e. RDF licenses)
