2.1.1. Formal compliancy definition
The flexibility of OpenMI version 2 can be recognized in the compliancy definition. The compliancy refers to a set of basic interfaces as well as to optional extension interfaces, e.g. for time and space dependent components. The IBaseLinkableComponent is the key interface.
OpenMI-compliance definition:
1. An OpenMI-compliant component must implement the IBaseLinkableComponent interface according to the specifications provided as comments in the OpenMI.Standard2 interface source code.
2. An OpenMI compliant component can also comply to one ore more extensions, by implementing the IBaseLinkableComponent interface and the extension interfaces which it wishes to comply to, according to the specifications provided as comments in the OpenMI.Standard2 source code.
3. An OpenMI-compliant component, optionally with extensions, ...
Alternative. 3a ... must, when compiled, reference the OpenMI.Standard2*.dlls/jars, which are released and compiled by the OpenMI Association.
Alternative. 3b ... must reference the OpenMI.Standard2 namespace, which is released by the OpenMI Association. 
4. An OpenMI-compliant component must be associated with an XML file, the so called
OMI file, which complies to (can be validated with) the LinkableComponent.xsd schema.
5. An OpenMI-compliant component must be associated with an XML file, which complies to (can be validated with) the OpenMICompliancyInfo.xsd schema. This file must be submitted to the OpenMI Association.
6. The OpenMI Association provides two additional interfaces that OpenMI-compliant components may or may not implement: the IManageState interface and the IByteStateConverter interface. However, if these interfaces are implemented, each method and property must be implemented according to the comments given in the OpenMI.Standard2 interface source code.
7. The OpenMI Association's downloadable standard zip file provides the only recognized version of source files, XML schemas and assembly files.
* at 2.: This leads to a main difference between OpenMI 1.x and OpenMI 2. In order to become 1.x compliant the classical time and space dependent component just had to implement the ILinkableComponent interface. This component now would have to implement the basic interfaces and the time and space specific extension for becoming OpenMI 2 compliant.
