**Affects:** SAREF **Situation:** The axiom below states that each and every task is accomplished by at least one device. This restriction is too strong and not necessary. One should be able to describe a task even if no device accomplishes it. ``` Axiom subClassOf( saref:Task ObjectMinCardinality ( 1 saref:isAccomplishedBy saref:Device ) ) ``` **Proposal:** To remove these axioms. **Status:** agreed during SmartM2M-2nd RG Meeting about 2 NWIs SAREFv3 and SAREF Com Framework V2 2019-05-06
