[2.0.0] - 2023-10-25

Major stuctural changes

For the version 2.0.0 we especially did some major structural changes on the OEO. Two new modules were introduced:

• The first one, oeo-sector, is a module on the same hierarchical level as the other content-related modules, i.e. oeo-physical, oeo-model and oeo-social. All sector-related entities were moved there from oeo-social.
• The second one, oeo-shared-axioms, is a module that imports the four content-related modules and contains all axioms that are introduced across modules.

This caused a lot of movement of entities, especially from oeo-shared. Many classes were moved back to their original module. This restructuring was done to foster the modularity, which makes the implementation easier and more error-prone. Yet, we had to break with the rule, that all axioms should live in the same module as their class of declaration. The full axiomatisation of a class is now only provided if the module oeo-shared-axioms is used. See also the wiki article on the modules of the OEO.

Further, the import process for UO and OMO were updated. All scripts and tools not essential for the building routine moved to a seperate repository. And finally, english language labels were added to (english) definitions and labels, to allow other language extentions in the future.
