This microservice provides the main path for updating and searching the graph - java-types defined in the OXM file for each version of the API define the REST endpoints - for example, the java-type "CloudRegion" in aai-common/aai-schema/src/main/resources/oxm/aai_oxm_v11.xml maps to /aai/v11/cloud-infrastructure/cloud-regions/cloud-region. +**aai/search-data-service** Abstraction layer for searchengine, supporting queries and updates.
