[rules-users] Synchronization of Working Memory

[Daniel E Chapman]

Hello!

We found a problem with the interaction of a serialized working memory and 
updates to the rules. 

Our process involves serializing the working memory to a database.  Later, 
when we load the serialized version of the working memory back from the 
database, if we've updated the rules it will detect that fact and it will 
throw away our carefully preserved working memory.  We suspect this is 
because the working memory maintains a reference to the rules as they were 
when the working memory is originally serialized.

I'm wondering if there is some way to accomplish what we're trying to do, 
either a way to serialize the working memory with no reference to the 
rules or some way to have the working memory update to accomodate any 
changes to the rules that may have occurred since it was serialized.

I know that some other rules engines, such as FairIsaac's Blaze engine, 
have complex schemes where you can have versioned rules in a repository 
and update the rules in that fashion.  I'm not sure that we're trying to 
do anything quite so complex, just a way to occasionally push out a new 
version of our rules without having to lose all of the work we've done to 
the working memory in the past.

(There may come a time where we may intend for the working memories to be 
cleared out, but I think we can do that in a manual fashion when the time 
comes.)

Thanks for your time, hopefully there's an easy answer!
