Abstract:
The current paper includes formal definition of the grammar of the proprietary scripting procedural language used by the proprietary EMS Workflow management Environment of Dextro Research Ltd. (DR) as an inseparable part of project metadata, which developers create using the DR Script Editor and DR Step Shop IDE tools. Unique features and operators of the language, such as Flow Identifier are defined and example usages are depicted and explained. The paper describes an innovative method of process steps addressing using flow identifiers and position context and current step number context. The trigger subsystem is described, the types of triggers of various events are listed, and examples are given. Output documents generation mode of the interpreter is functionally described and special built-in operators in the language grammar and global variables, aim to make the process as easy as possible.
Keywords –workflow, flow identifier, programming language, flow operators. |
