v2.0.2

• Bug fix for WADL Parameter. Was previously subclass of SkillParameter but WADL parameters are also used to describe SkillOutputs. Has been fixed by adding inverse properties as well as a class expression
• Adds missing types for PLC2Skill parameters

v2.0.1

Minor update that just uses new versions of the underlying ODPs. Brings e.g. two new inverse properties of DIN EN 61360

v2.0.0

Breaking changes

New Skill classes have been added to be able to model skills that are controlled via a OPC UA variable. This can be used for e.g. PLCs that are not capable of OPC UA methods.

• The class OpcUaSkill is now a super class for OpcUaMethodSkills and OpcUaVariableSkills. OpcUaMethodSkills are what was previously called OpcUaSkill: Skills that can be controlled via OPC UA Methods. An OpcUaVariableSkill is controlled by setting an OPC UA Variable to a certain integer value
• The class OpcUaSkill is used to map services of a Module Type Package (MTP).
• A special parameter and output class has been added to specify command variables and variables that reflect the current state
• Required values have been added to specify the value that has to be set in order to invoke a certain transition (conforming to MTP standard)
• Assured values have been added to specify the value that are returned as a feedback of the current state (conforming to MTP standard)

-> Skills that used to be OpcUaSkills have to be changed to OpcUaMethodSkills now. Furthermore, new ObjectProperties "providesOpcUaMethodSkill" and "executableViaOpcUaMethodSkill" should be used instead of the old more generic "providesOpcUaSkill" and "executableViaOpcUaSkill", respectively

v1.0.4

Adds SkillOutput and SkillVariable (which is a super class of SkillParameter and SkillOutput)

v.1.0.3

• Adds first version of skill dependencies

v1.0.2

• Updated ontology dependencies to v1.4.0
• Fixes problems with German umlauts
