Service-Microservice Architecture for Context-Aware Content Delivery in National Geoinformation Center of Bulgaria

摘要

National Geoinformation Center of Bulgaria is a national scientific infrastructure - a consortium with a mission to produce and provide value-added products of Earth observation data gathered by various agencies governed by the state or received through international cooperation. The architecture of the information system of the center is presented - a layered structure that implements concepts of service and microservice, building an organization that reflects the federated nature of the consortium. The paper reviews various implemented design decisions within the perspective of context-aware systems. Four sources of data exploited for the determination of the context of the user are described. The paper concludes with three scenarios prepared as patterns for building context-aware services within the center.
