Tassilo Pellegrini presenting DALICC at Semantics 2017

On September 12, 2017 DALICC presented a poster atn the 13th International Conference on Semantic Systems - Semantics 2017 - in Amsterdam, giving insights into the extended DALICC rights expression language (REL).

DALICC follows a deontic approach to express machine-readable permissions, prohibitions and duties defined in a license. DALICC utilizes the ODRL 2.0 ontology in combination  with CCRel. Additionally DALICC utilizes an extended set of properties that are necessary to capture the full semantic spectrum of legal expressions defined in a license text. By doing so DALICC allows to represent property rights policies in a legally valid and machine-processable way.

The DALICC vocabulary extensions evolved from an in depth analysis of 15 standard licenses (including CC, APACHE, BSD, GPL MIT) under the supervision of legal experts. The following expressions need to be added to cover the full semantic spectrum of copyright statements:

PROPERTIES AFFECTING THE ASSET

PROPERTIES AFFECTING THE LICENCE

dalicc:charge

dalicc:addStatement

dalicc:sublicense

dalicc:attributionNotice

dalicc:promote

dalicc:attachOffer

dalicc:publish

dalicc:chargeOffer

 

dalicc:irrevocable

 

dalicc:modificationNotice

 

dalicc:noWarrantyNotice

 

dalicc:patentFree

 

dalicc:patentNotice

 

dalicc:perpetual

 

dalicc:royaltyFree

 

dalicc:worldwide

A detailed documentation of the DALICC REL extension is to be provided in the near future.
