The document summarizes the DALICC (Data Licenses Clearance Center) project. The project aims to develop a software framework that reduces the costs of clearing licenses for derivative works by providing tools to choose licenses, check compatibility, and resolve conflicts. It will represent licenses in RDF and use rules and semantics to reason about licenses and detect inconsistencies. The framework will include components for composing, annotating, and negotiating licenses through a license library and API. The goal is to increase productivity and reuse of data by easing license clearance.

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

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.

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. 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)
