6. Workflow Business Workflow
Workflow, by definition, is the automation of a business process.
Information or tasks are passed from one participant to another for action, according to a set of procedural rules.
It is a set of tasks assigned to people or programs in order to accomplish a piece of work.

9. Project Overview Researched the Tieflow DTD
Researched on the XPDL 2.0 and BPEL4WS1.1 Specification
Mapping Elements/Attributes of Tieflow
Difficulties faced during Mapping
Omission of BPEL4WS1.1 from the Requirement
11/13/2019

10. Project Overview Developed the configuration file
Handled special scenarios
Developed the design for the XML Translator

22. Issues During Design Unmatched Elements/Attributes Example
Adding class name in configuration file
Preserved Data on Missing Elements
11/13/2019

23. Issues During Design Missing Elements (Process – ProcessHeader)
Package:Process: TimeUnit (Tie flow )
Package:WorkFlowProcess:ProcessHeader:DurationUnit (XPDL)
Generated when required.

24. Issues During Design Depth Issue
Maintaining hierarchy in configuration file
Package:Process:Role:id
Package:WorkflowProcess:Lane:id
Package:Role:id
Package:Lane:id
11/13/2019

25. Issues During Design Keeping track of parents Still working on code
11/13/2019

26. Satisfied requirements
Generic translation component
External configuration options
TieFlow to XPDL transformation
Command line interface

32. Helper classes Class TieFlowXmlConverter Class XMLTranslatorUtility
GUI
Accepts input file name
Display status
Creates output XML file
Class XMLTranslatorUtility
Loads configuration file to hash maps
Creates fully qualified node names on demand
11/13/2019

33. Class XMLTranslator API methods for TieFlow Java applications
Reads input XML file using DocumentTraversal interface
org.w3c.dom.traversal.DocumentTraversal
Creates appropriate NodeTranslator class using reflection
11/13/2019

34. Class NodeTranslator Four Subclasses based on type of Translation
Creates the output node in the appropriate parent
Creates parent node recursively when required
