Prefer Rule Editor Framework without DTL(too expensive) if:

• Working on a single protocol(e.g.,  HL7)

It can be simple and efficient if:

• Working on a single cloned object(e.g.,  cloned from HL7 msg)

With benefits:

• Separate Rules logic from the code
• Edit rules externally with help of Export & Import in Business Rule List page
• Replace Open Source Drools and bring in their customers

Each DTL calls “ConstructClone” to make a copy of the message before making any changes to it. There will be hundreds of cloned-objects in case of hundreds of DTLs

It is expected to run the rules chain by using Rule Editor without DTL, namely against a SINGLE cloned-object. It will be much efficient in case of hundreds or thousands of rules under same protocol, for example HL7 2.3, ORU_R01.

Question is how to pass the cloned-object from one rule to another, and send the modified object to target Process or Operation in Rule Editor?
 

The case is currently implemented by using other Open Source Utility.
I would find the efficient workaround for migration, but other than DTL mentioned-above

Enrico, Thank you very much! I stop here with you
