Jumping in on this thread at a random point to pass along a milestone (IMHO) in the Semantic Web world - with apologies to those for whom this may be a duplication: Just announced: The Semantic Web Services Initiative (SWSI) has released architecture requirements for Semantic Web Services. Highlights included below - including service lifecycle and ontology management. [1] http://www.daml.org/services/swsa/swsa-requirements.html Kind Regards, Joe Chiusano Booz | Allen | Hamilton Strategy and Technology Consultants to the World HIGHLIGHTS: (1) Semantic Web Services are viewed as a way to extend the capabilities of web services in the direction of dynamic interoperability, thereby making it possible for clients to successfully utilize web services without prior arrangements between people that are realized in rigid software protocols, and immutable ontologies or meta-data. (2) The functions addressed by the Semantic Web Services Architecture will include: * Dynamic Service Discovery: The capability for a software agent to identify candidate services for particular objectives; includes candidate service matchmaking and brokering functions. * Service Selection and Composition: The capability to dynamically select and compose services to achieve some objective; includes failure recovery and compensation mechanisms, as well as choreography interpretation and execution. Also includes ontology translation services. * Negotiation and Contracting: Ability for two agents to mutually formulate a shared agreement in terms of performance to be provided; includes dispute resolution and compliance. * Semantic Web Community Support Services: Capabilities associated with sharing semantic descriptions, ontologies, ontology mappings, and service catalogs within and across communities, and managing these items as well. * Semantic Web Service Lifecycle and Resource Management Services: Capability to management the lifecycle of Semantic Web Services. * Other: Includes QoS requirements (time, cost, reliabilty, operational metrics, etc.), and the capability to discover a service based on these factors.
