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.

Web service syndication system

A system for storing and dynamically updating data represented in the Extensible Markup Language (XML) which separates the data values in at least some of the elements of an XML document and places those data values in relational database tables where they may be processed using conventional RDBMS techniques. The hierarchical structure of the XML document is saved separately in an XML skeleton object from which element data other than primary key values has been removed. The XML documents document type definition (DTD) is stored, along with additional property data used the RDBMS, in an XML Definition object. The additional property information includes the identification of primary key data values which are used to link the structural definition data to the value data stored in the tables, the designation of data types used for more efficient storage of data from predetermined XML elements, the designation of selected element data for indexing and for column storage, and the designation or relational integrity constraints which help insure that logically connected data is not inappropriately deleted or updated. The XML data as stored in the relational tables can be retrieved as a complete XML document, or selected XML elements can be retrieved by themselves, by merging the table data into the XML skeleton.

Dynamic XML processing system

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.
