In JMC 8 we're planning some major changes for the rules API. Some of them intended to make it more secure and easy to use the rules/heuristics in services.

• No more HTML in rule results
  (Probably support a subset of markdown or something similar)
• Re-use of results/partial results
  • This will require a DAG of rule dependencies, as well as allowing rule result objects to contain more complex data than a score, some text, and an item query.
• API improvements
  (JMC 8 will require JDK 8, even for core libraries. We can improve the API surfaces.)
• The user should be able to generate a JFC file based on rule event suggestions
• ...more to come.

The following is a suggested list of features the new Result objects should implement: (the italicized items would be optional)

• A one sentence summary
• A severity of N/A, OK, INFO or WARNING
• A theoretical explanation of the observed issue
• A possible solution to the issue
• If applicable, a command line parameter to add/change/remove
• A list of event settings that can be used to improve the result. A result that contains this should probably also contain some information about the possible runtime performance impact that using these settings might have.
  
• A dictionary of calculated values, with a String based ID and a number / unit pair value.
