The module was basically part of GSOC 15,16 and was not added on OpenMRS modules list. It may need some changes and QA before adding to module list of OpenMRS. We are happy to provide guidance or any help in understanding the module.
We are still working on few refactorings and hopefully would be able to share the updated omod by tomorrow with proper naming conventions and finalized schema. However, here is a copy of omod of current master branch https://drive.google.com/file/d/1RN1ea1NROdwd5gR__TeDASMuDSXHI-SK/view?usp=sharing. This can provide a view of how module works and what are different pages available.
Apologies for the delay but these changes are mandatory so that we can make it part of standard OpenMRS module repo.
This is tested and working fine on openmrs 2.0.6. Hopefully it would work on 2.1.x as well. If it doesnot let me know I can change the build version to 2.1.x.
Sharing the document shortly. However, if you are familiar with OpenMRS REST architecture the code is here. URL would be like /openmrs/ws/v1/cohortm/[cohortrole/cohort/cohorttype/…]
