Manipulation of complex variables in orchestration applications

Abstract:

An example embodiment provides a high level language (called a pseudo language herein) built on top of (or representing an abstraction layer on top of) Business Prosecution Execution Language (BPEL), which incorporates three new specialized functions, or "verbs," that facilitate developer friendly operations that are readily validated during design time using schema awareness, and that enable schema-aware implementations of complex variable modifications during runtime. The pseudo language and accompanying verbs (e.g., append, assign, remove), in combination with both design time and runtime awareness of the schema of the complex variables involved in a given operation, facilitate manipulation of data in complex variables at different steps of an orchestration flow; enable developers to selectively and efficiently update fields or elements of a complex variable without risking inadvertent loss of data in the complex variable during runtime; enable specific modification of leaf nodes of complex variables while leaving parent variables intact; and so on, while further removing or mitigating various design-time validation steps or responsibilities that developers currently have when implementing orchestration flows.
