BPEL Script
BPELscript is a language to specify BPEL processes. It provides a compact syntax inspired by scripting languages such as JavaScript and Ruby and a full coverage of all features provided by BPEL. History The Business Process Execution Language (BPEL) is an XML-based language to specify business processes with the intention to "act as the central controller of the business process". It provides a standardized way for programming in the large in a service-oriented world ( SOA). BPEL is a programming language and does have a graphical representation. Mappings from graphical languages such as the Business Process Modeling Notation (BPMN) to BPEL are available, but programmers familiar to syntax like Java, C, ... are disregarded. Therefore, especially for prototyping or teaching, it would be nice to have a programming language which omits the XML-overhead of BPEL but offers the same features as BPEL. One option is to force the programmers to learn a completely new syntax. The other opt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BPEL
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. Overview One can describe Web-service interactions in two ways: as executable business processes and as abstract business processes. # An ''executable business process'': models an actual behavior of a participant in a business interaction. # An ''abstract business process'': is a partially specified process that is not intended to be executed. Contrary to Executable Processes, an Abstract Process may hide some of the required concrete operational details. Abstract Processes serve a descriptive role, with more than one possible use case, including observable behavior and/or process template. WS-BPEL aims to model the behavior of processes, via a lan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Script (computing)
A scripting language or script language is a programming language that is used to manipulate, customize, and automate the facilities of an existing system. Scripting languages are usually interpreted at runtime rather than compiled. A scripting language's primitives are usually elementary tasks or API calls, and the scripting language allows them to be combined into more programs. Environments that can be automated through scripting include application software, text editors, web pages, operating system shells, embedded systems, and computer games. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, it is also known as an extension language. Scripting languages are also sometimes referred to as very high-level programming languages, as they sometimes operate at a high level of abstraction, or as control languages, particularly for job control languages on mainframes. The term ''scripting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

YAWL
A yawl is a type of boat. The term has several meanings. It can apply to the rig (or sailplan), to the hull type or to the use which the vessel is put. As a rig, a yawl is a two masted, fore and aft rigged sailing vessel with the mizzen mast positioned abaft (behind) the rudder stock, or in some instances, very close to the rudder stock. This is different from a ketch, where the mizzen mast is forward of the rudder stock. The sail area of the mizzen on a yawl is consequentially proportionately smaller than the same sail on a ketch. As a hull type, yawl may refer to many types of open, clinker-built, double-ended, traditional working craft that operated from the beaches of Britain and Ireland. These boats are considered to be linked to the Viking or Nordic design tradition. Most of these types are now extinct, but they include the Norfolk and Sussex Beach Yawls (called "yols" by the men who crewed them), which were probably the fastest-sailing open boats ever built. A yawl i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

XPDL
The XML Process Definition Language (XPDL) is a format standardized by the Workflow Management Coalition (WfMC) to interchange business process definitions between different workflow products, i.e. between different modeling tools and management suites. XPDL defines an XML schema for specifying the declarative part of workflow / business process. XPDL is designed to exchange the process definition, both the graphics and the semantics of a workflow business process. XPDL is currently the best file format for exchange of BPMN diagrams; it has been designed specifically to store all aspects of a BPMN diagram. XPDL contains elements to hold graphical information, such as the X and Y position of the nodes, as well as executable aspects which would be used to run a process. This distinguishes XPDL from BPEL which focuses exclusively on the executable aspects of the process. BPEL does not contain elements to represent the graphical aspects of a process diagram. It is possible to say th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Workflow
A workflow consists of an orchestrated and repeatable pattern of activity, enabled by the systematic organization of resources into processes that transform materials, provide services, or process information. It can be depicted as a sequence of operations, the work of a person or group, the work of an organization of staff, or one or more simple or complex mechanisms. From a more abstract or higher-level perspective, workflow may be considered a view or representation of real work. The flow being described may refer to a document, service, or product that is being transferred from one step to another. Workflows may be viewed as one fundamental building block to be combined with other parts of an organization's structure such as information technology, teams, projects and hierarchies. Historical development The development of the concept of a workflow occurred above a series of loosely defined, overlapping eras. Beginnings in manufacturing The modern history of workfl ...

WS-CDL Service choreography in business computing is a form of service composition in which the interaction protocol between several partner services is defined from a global perspective. The idea underlying the notion of service choreography can be summarised as follows: "Dancers dance following a global scenario without a single point of control" That is, at run-time each participant in a service choreography executes its part according to the behavior of the other participants. A choreography's role specifies the expected messaging behavior of the participants that will play it in terms of the sequencing and timing of the messages that they can consume and produce. Choreography describes the sequence and conditions in which the data is exchanged between two or more participants in order to meet some useful purpose. Service choreography and service orchestration Service choreography is better understood through the comparison with another paradigm of service composition: service orch ...
