Add ability for sequential and parallel task specifications for Workflows
-------------------------------------------------------------------------
Key: OODT-70
URL: https://issues.apache.org/jira/browse/OODT-70
Project: OODT
Issue Type: Improvement
Components: workflow manager
Environment: indep. of env.
Reporter: Chris A. Mattmann
Assignee: Chris A. Mattmann
Fix For: 0.2
There has been a lot of internal JPL work on flushing out new ideas with the
workflow manager. One of those new ideas is to explicitly support
differentiating between different types of
{code}org.apache.oodt.cas.workflow.WorkflowTask{code} entities, classifying
them as *sequential* (their current form) versus *parallel* (those that deal
explcitly with branch and bound). Even though the current workflow system can
support these activities, they are largely code-based and require modification
and intrinsic knowledge of the Workflow event system.
It would be nice to simplify this for the users and allow task.xml,
conditions.xml and *.workflow.xml files (or explicit WorkflowRepos) to support
this nomenclature.
I'll attach a proposed spec of what the updated XML files would look like using
this paradigm. Then my goal is to take the existing workflow system and augment
it with this functionality.
