I pushed a change draft for Issue #146 , “Make result.ruleId a hierarchical string to accommodate 'sub-rules'”: Documents/ChangeDrafts/Active/sarif-v2.0-issue-146-hierarchical-rule-id.docx We will move its adoption at TC #32 on Wednesday, February 13 th 2019. This isn’t one of the issues we discussed at the F2F. This is an issue Michael and I had discussed previously, but I’d never gotten around to writing the change draft. Thanks, Larry
