US Patent 9026567 Publish-subscribe system

A publish-subscribe system publishes events associated with one or more objects represented by files within a file system. The files may be accessed using a file system application programming interface by both publishers and subscribers. Each file may contain an identifier and a plurality of attributes and each attribute may have a name and a value. The files and the associated objects may be persisted to compensate for restarts and failures of a computing platform hosting the system for publish-subscribe.
