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.
  • No labels
