Abstract:

Techniques are provided for defining and coordinating execution of a compound service, which uses results from a plurality of base services, over a network. A sequence in which a plurality of modules must be executed to perform the compound service is specified in dependency information, and the modules in the sequence are executed according to the dependency information and under the management of a service execution adapter. Each module operates upon messages according to module properties, and is able to communicate using event messages.

Abstract:

A dynamic services infrastructure accepts data describing data resources and stores that data in a relational database from which it may be retrieved to handle service requests issued by application programs. The database stores Service Definition data which is initially supplied in the form of XML Service Descriptor documents which are then mapped into the database from which they may be accessed. Each Service Definition includes an input specification which identifies the address of a resource as well as the nature of the input data to be supplied to the resource with the request, and further includes an output specification which describes the nature of the output information which is supplied by the resource in response to the request. The Service Definition further includes information describing the service provider which supplies the resource, test information including fixed input and output values which permit the operability of the resource to be verified, update information which permits the infrastructure to insure that the Service Definition information is kept current, and security information which permits the system to validate users and provide secure encrypted information exchanges. When a client sends a request for services to the infrastructure, obtains the service description for the desired resource from the database, transmits an output information request to the address specified in said the service description, supplying input information meeting the specification contained in said particular service description to said particular resource, and receives and routs output information provided by said particular resource in response to said output information request to the executing application program.

Abstract:

A syndicator for disseminating Web services and other resources from service and content providers to service consumers and for establishing and implementing subscription agreements specifying the terms upon which digital assets are provided to subscribers. A registration database stores a service description for each of a plurality of different Web services and other resources. Each stored service description contains an input processing specification, an output processing specification, and the specification of the business terms upon which the described service or resource is offered by its provider to subscribers. A subscription manager conducts a negotiation with a prospective subscriber and receives from the subscriber an acceptance of the business terms upon which a specified Web service or resource is offered to establish a subscription agreement. Event tracking records information describing the performance of each service on behalf of each subscriber to perform subscription accounting functions.

Abstract:

A cache system for storing request messages expressed in Extended Markup Language (XML) and the responses to those messages. The inbound request message, which typically takes the form of an HTTP request message containing an XML request document as its payload, is received via the Internet from a remote sender. The XML request portion of the inbound message is then translated into canonical form, preferably conforming to the predetermined standard canonical form established as an Internet standard. The canonical XML request is then compared with previously received canonical requests. To speed the process of comparing the inbound canonical XML request with previously cached XML requests, an access key, such as a checksum or a hash integer, is generated from the content of the inbound request. The access key is then used to identify zero or more prior canonical requests which may match the inbound canonical request. A character-by-character comparison is then made between the inbound canonical request and those cached requests that share the same access key to determine whether a match exists. If a match is found, the cached response previously sent in response to the matching prior canonical request is returned to the remote sender. If a match is not found, the requested information is retrieved and packaged into a response message which is returned to the sender, and the both the keyed canonical XML request and the response are placed in cache memory.
