7. Session #, Speaker Name
Need for a Task Editor
No common graphical method of creating tasks in SORCER
Each provider must have own GUI interface
Users must learn each providers interface
Provide easier development of new services
No method for creating Jobs
No method for saving and reusing Jobs.

8. All About Contexts A Context is a set of instructions for a provider.
The context various depending on the provider and the method being executed.
Contexts can specify anything about a provider
Example:
The context for makeDeposit in the AccountTester is: deposit/amount=amount
Mike Sobolewki

9. Edit the Context?
Why would we want to edit the Context before we launch the Task?
The Context can often described input variables that are not static, editing it allows us to change them.
Example: The AccountTester would be useless if you could not specify how much you were depositing or withdrawing.
Mike Sobolewki

10. Output of the Task Tasks return a Context for their output
In the case of a simple Task the output is returned the user
In a Job the output is used as input for the next Task
Mike Sobolewki

11. Implementation Issues
Due to various time constraints and implementation issues some sections do not work.
List View – didn’t get time to finish it
Launch Service doesn’t actually launch it – Bug in ServiceTask.exert where provider is not found, disabled the exert code to show what it would look like if it worked….

Add save Context
Code cleanup and documentation
Separate from Cataloger Service
