63 results about "Business Process Execution Language" patented technology

The Web Services Business Process Execution Language (WS-BPEL), commonly known as BPEL (Business Process Execution Language), is an OASIS standard executable language for specifying actions within business processes with web services. Processes in BPEL export and import information by using web service interfaces exclusively.

Linked data-based multiplexing method of business process execution language (BPEL) templates and services and system thereof

The invention discloses a linked data-based multiplexing method of business process execution language (BPEL) templates and services and a system thereof. The system comprises a model layer, a control layer, a user interface (UI) layer and a service asset library, wherein the model layer is used for providing models required by graphing and various functions of the whole system; the control layer is used for carrying out a control operation on a visualization process in the whole system, and further, realizing functions of script parsing of BPEL, template extracting and packaging, service combining and business exporting; the UI layer is mainly used for the functions of a palette, an editing window, an attribute view, an outline view and a guide view; and the service asset library specifically consists of field bodies, template bodies and service bodies. With the adoption of the linked data-based multiplexing method of the BPEL templates and services and the system thereof, the multi-granularity service asset multiplexing which includes the multiplexing by taking a BPEL subprocess as a template and the atomic Web service multiplexing can be realized; and the development efficiency for service combinations can be increased so as to shorten a development cycle through a pre-designed process template or a user-defined multiplexing template.

Event-handling-based coal mine alarm system and method

The invention discloses an event-handling-based coal mine alarm system, mainly comprising an event processing module, an issuing and subscribing module, an alarm processing flow module, a control server module and a client display module, wherein the event processing module is used for receiving an original data stream monitored by a coal mine sensor, acquiring an event concerned by a system by virtue of an event processing engine and issuing the event to the issuing and subscribing module in a specific theme; the issuing and subscribing module is used for realizing an issuing and subscribing service engine and interaction of processing messages; the alarm processing flow module is based on a service flow execution language and is used for describing an alarm processing flow and calling corresponding web service in the alarm processing flow; the control server module is used for subscribing a theme event concerned by the system, triggering an alarm flow when receiving the alarm event, being taken as a proxy of interaction between the flow and a human and interacting with the flow, storing an alarm condition and initiatively pushing the alarm state to the client display module to be displayed; and the client display module is used for communicating with the control server module and providing a user interaction interface and content display.

Service composition-oriented declarative transaction integration method and system

The invention discloses a service composition-oriented declarative transaction integration method and a service composition-oriented declarative transaction integration system. The method comprises the following steps of: (1) preprocessing service composition language, namely a business process execution language (BPEL)-based service composition specification, identifying and eliminating transaction dependence existing among different activities; (2) describing and annotating a transaction strategy for the preprocessed service composition specification, guaranteeing that the annotated activity accords with a certain transaction protocol specification; and forming a transaction annotation-containing service composition specification by the preprocessed service composition specification andan annotation file of the transaction strategy; and (3) explaining and executing the transaction annotation-containing service composition specification to finish a Web service composition of a predetermined service. By integrating a transaction frame and a protocol of the conventional Web service and utilizing the conventional service composition engine and the Web service-oriented transaction protocol, automatic transaction design and execution in the service composition are partially supported, and the reliability of the Web service composition is enhanced.
