A method of invoking a service of a Web service provider using a client terminal comprises obtaining a template WSDL binding definition, communicating with the Web service to request the generation of a concrete WSDL binding and invoking the Web service using the concrete WSDL binding. A method is also provided for a Web services provider to provide asynchronous callback messages to a client, as well as the client and Web server apparatus.

Asynchronous messaging in web services

In one embodiment, a first text fragment is made available for copying from a fragment repository. The first text fragment is electronically linked to a second text fragment that is a copy of the first text fragment, the second text fragment included in a container external to the fragment repository. A rating is provided for a derivative of the second fragment created within the container. A third text fragment that is a derivative of the second text fragment is received at the fragment repository. The first and third text fragments are electronically linked, and the third text fragment is made available for copying.

Electronically linking and rating text fragments

The invention concerns a method of sharing state information. In the method, data presented to a user from a template file of a referring site of a distributed computer network is presented to the user in a style dictated by the referring site. During interaction between the user and the referring site, user entered data is captured at the referring site where it is used to modify data of the template file as part of a transaction. At a point in the transaction at which it is desired or required to transfer transaction data to a nominated site to further process the transaction, state information comprising both data from the template file and style data concerning the style of the referring site are transferred by the referring site to the nominated site. Thereafter, the nominated site when continuing processing of the transaction utilises the style data of the referring site.

Sharing of state information

A web form is generated by applying a stylesheet to a set of rules which will subsequently be used to transform client selection data submitted via the web form. Transformed client selection data is used to update a record of the client's state for the current session, and the record is identified for updating with the transformed client selection data either using a client identifier returned with the client selection data, or when the selection data is returned via a different client, an identifier for the session record.

Method of processing data from a submission interface

A parser for parsing documents comprising a Document Order List Creator, a YPath Table Creator, and a ZPath Table Creator. The arrangement of the Document Order List creator being such that it is adapted to produce a Document Order List (DOL) correlating a unique index number with an associated node, and the Document Order List creator being adapted to allocate each node in a document parsed its own unique index number in the DOL. The arrangement of the YPath Table Creator is such that it is adapted to produce a YPath Table having a set of sequences of node names representative of all sequences of node names encountered in traversing from the root node to all possible nodes in the document parsed, and associated with each sequence of node names a corresponding group of index numbers corresponding to the index numbers in the DOL for which the associated sequence of node names is true. The arrangement of the ZPath Table Creator is adapted to create a ZPath Table having a set of sequences of ordinals representative of ordinals of those nodes encounterable in traversing from the root node to all possible nodes in the document, the ordinal of a node being the integer value position of the node amongst those nodes of the same name which share the same parent node, and associated with each set of sequences of ordinals, a corresponding group of index numbers corresponding to the index numbers in the DOL for which the associated sequence of ordinals for nodes is true.
