[rules-dev] Template Rules and Knowledge Agent Change Sets

Hello, In my application I create rules using a template. The application allows users to specify the when clause of a rule and then builds a knowledge base by taking the when clauses stored in the database and joining them with the template. I am trying to solve the problem of incrementally updating the knowledge base when the information stored in the database has been updated/inserted/deleted without completely rebuilding the entire knowledge base. I was looking at using Knowledge Agent change sets to do this. I was wondering if there are any options other than supplying a change set xml file to manipulate the knowledge base? I believe I can make it work with what is outlined in the documentation and in the blog posts but I want to understand all my options so I can make a solid implementation decision. Any help is greatly appreciated. Thanks!
