Abstract: A system and method for typing resources in a distributed system is provided which enables flexible searching mechanisms for finding distributed resources. The distributed system includes at least three types of resources: service, vocabulary and contract resources. The service resource includes the implementation logic for the service. A contract resource contains interface data used for accessing resources. The vocabulary resource contains an attribute schema defining attributes used to describe resources. Each resource—including service, vocabulary and contract resources—is typed by associating one or more vocabulary resources and one or more contract resources with the resource. The vocabulary resources explain the meaning of attribute lists describing the resource and enable the resource to be discovered. The contract resources provide data for accessing the resource.

Abstract: A method and system for enabling a client to programmatically manage the lifetime of groups of distributed resources is herein provided. The method includes grouping client-specific resource data usage generated from blocks of instruction sequences bounded by scope instructions. A “begin scope” instruction invokes a method initiating the temporal scope. Client-specific resource data generated during execution of subsequent instructions is tracked by the distributed infrastructure. When an “end scope” instruction is received, the client-specific resource data tracked under the temporal scope is deleted from the distributed infrastructure. Client-specific resource data may be tracked under two types of temporal scopes: a transient and a persistent temporal scope. Data tracked under a transient scope does not survive beyond the lifetime of the client connection, whereas data tracked under a persistent scope may survive beyond the lifetime of the client connection. Lastly, temporal scopes may generally be nested.

Abstract: A conversation definition language (CDL) is disclosed that programmers may use to define sequences of interactions for communicating with a web service to facilitate use of the web service. CDL enables web services provided by different entities to engage in flexible and autonomous interactions. Using CDL, services can communicate by exchanging messages, and the message exchanges are expected to follow a specific pattern (i.e., a conversation). CDL is used to define the conversation, such that a service may expect a particular message in response to transmitting a particular message. CDL includes document type descriptions, interactions and transitions for describing a conversation. The document type descriptions describe the messages that may be exchanged. The interactions describe the type of actions (e.g., receive and/or transmit a message) that may be performed, and the transitions describe the possible sequences of the interactions.

The distributed system includes at least three types of resources: service, vocabulary and contract resources. The service resource includes the implementation logic for the service. A contract resource contains interface data used for accessing resources. The vocabulary resource contains an attribute schema defining attributes used to describe resources. Each resource—including service, vocabulary and contract resources—is typed by associating one or more vocabulary resources and one or more contract resources with the resource. The vocabulary resources explain the meaning of attribute lists describing the resource and enable the resource to be discovered. The contract resources provide data for accessing the resource.

Abstract: A method and system are provided for defining a search space of a community in which a client may search for resources. A client providing a resource registers the resource with a core. The core then lists the resource with an advertising service, which serves multiple cores. A client searching for a resource can search in the client's core and within the advertising service serving the clients core. In addition, a client searching for resources can define a community of advertising services remote to the client's core, then designate the community when sending an attribute-based search for computer resources to the client's core. In some embodiments, once a community is defined, a client can subscribe to an events within the community by searching for an event distributor within the community. The client is then notified of events occurring within the community that match the client's event subscription.
