Phase I of the Synchronization and Web Services tools is a dictionary import tool for OpenMRS. Included in this task is setting up a framework for further web-based services to utilize.
Dictionary Import should allow you to define a server with OpenMRS installed on it and with a master copy of the dictionary. After that server is confirmed to have a valid install of OpenMRS on it, a button click will allow you to take all Concepts from the parent dictionary and have them copied to the child instance. Communication of data will be done via web services/SOAP, and use JAXB for object serialization.
