AGGREGATION AND FEDERATION OF DISTRIBUTED SERVICE ENTITIES AND ASSOCIATIONS

Network services may include data associated with one or more entities. An aggregator service may host respective application programming interfaces (APIs) of the services at a single endpoint of thenetwork such that the entities, including associations and relationships between entities, may be federated. For example, the services may register the entities of which the data of each of the services is associated with through a declarative entity model to establish an API schema for each of the services, which may be published at the aggregator service. In response to receipt of a request forentity related data from a client, the aggregator service may employ the declarative entity model to determine which of the services are associated with the entity related data such that a query may be submitted to the services, and how to aggregate responses to the query received from the services for transmission to the client. 网络服务可以包括与个或多个实体相关联的数据。聚合器服务可以在网络的单个端点处托管服务的相应应用编程接口(API)，以使得实体(包括实体之间的关联和关系)可以被联合。例如，服务可以通过声明性
