Abstract: The described technology is generally directed towards an abstraction and file model used for subscriber service and publisher service communication. The abstraction and file model enables dynamically changing the underlying communication mechanisms and introducing optimizations such as caching (reducing latency) and batching (improving bandwidth utilization) transparently, without any change to the subscriber or publisher code. The abstraction also facilitates introducing intermediate lightweight message-oriented middleware and provides for transparently scaling communication.

Abstract: The described technology is generally directed towards matching subscriber services to publisher services based on any number of arbitrary subscriber-specified attributes. In general, each publisher services register its capabilities as a set of attributes in a repository data store, e.g., a database. When a subscriber service wants a matching publisher service, the subscriber service specifies which attributes the subscriber service wants matched, and the repository's affiliated matching process uses the registered attributes of the publisher services to seek a match.
