Embodiments of the present invention provide a method, system and computer program product for directional optimization of policy statements for a Web service. In an embodiment of the invention, a method for directional optimization of policy statements in a policy document can be provided. The method can include loading a policy document referenced for a Web service, extracting a policy from the policy document, and determining whether the extracted policy is bi-directional or direction agnostic. A single run time presentation for the extracted policy can be created when the extracted policy is direction agnostic. Otherwise, separate run time presentations can be created for each direction of the extracted policy when the extracted policy is bi-directional.

Directional optimization for policy evaluation

Delegation of processing functions to specialized appliances in an enterprise is provided. An appliance typically comprises a combination of hardware and resident firmware that addresses needs in a computing environment, such as by providing common message transformation, integration, security, filtering and other functions. Delegation is carried out by specifying at least one XML function for front-process offloading from a server to a corresponding appliance configured to receive messages pushed towards the server, communicating management directives to the appliance for configuring the appliance to perform the specified XML function(s) according to specific requirements dynamically specified by the server and communicating instructions to the appliance so that the appliance augments received event messages with intermediate processing information based upon the front-process offloading, as received event messages pass through the appliance.

High-performance XML processing in a common event infrastructure

Embodiments of the present invention address deficiencies of the art in respect to extensible markup language (XML) data processing and provide a novel and non-obvious method, system and computer program product for inter-device transfer of parsed XML documents. In one embodiment of the invention, a markup serialization method can be provided. The method can include receiving a request in a second computing process for offloaded parsing of markup from an application in a first computing process, retrieving markup from the application, parsing the markup in the second computing process to produce a serialized data object for the markup, placing the serialized data object into shared memory for the application, and returning a reference to the serialized data to the application.

Coordinated XML data parsing and processing from within separate computing processes

A flexible system for associating a data stream with one or more secure control files based on mapping self-declared identifiers to trusted identifiers. It has particular application in relation to XML documents, XML Schema, XPath/XSLT/XQuery and WSDL file processing. Control file identifiers are detected in a data stream and transformed to map to new identifiers which are correlated to locations which are more secure and/or accessible. Optionally, copies of the control files are then stored and maintained at the new locations.

System and method remapping identifiers to secure files

A markup language processing device processes markup language messages by receiving a message containing portions of tagged data formatted in a markup language and applying a transform selection rule set to at least one tagged rule selection data portion in the message to select at least one markup language transformation to apply to the tagged pre-transform data portion within the message. The markup language processing device applies the selected markup language transformation to transform the tagged pre-transform data portion to a tagged post-transform data portion according to a transformation function and then conditionally forwards the message. The markup language processing device operates on behalf of a computerized device that is not required to process the message due to operation of the at least one markup language transformation within the markup language processing device. The markup language processing device can process XML message for security and other purposes thus offloading such processing requirement from server computer systems.

Methods and apparatus for processing markup language messages in a network

A request for a software service utilizes a service intermediary. The service intermediary 1) checks the request to confirm that it conforms to XML well-formedness, and 2) validates the schema of the request. If the request passes both tests, then flags are appended to the request, which is sent to a service provider. The flag indicates to the service provider that the request has already been checked and validated, such that the service provider only needs to provide the requested service, without redundantly checking and validating the request.
