Hi, it seems that the metadata is a bit scattered around the place. A) Some metadata are at rules themselves, e.g. as returned by getExecuteAfter(). B) Some are sunken into the dark depth of ~.rewrite.Context, like rewriteCtx.put(RuleMetadata.CATEGORY, DEFAULT_CATEGORY); However when I try to retrieve this, Object cat = event.getRewriteContext().get(RuleMetadata.CATEGORY); I get null. So I debugged and found the data stored in a weird data structure, context.map[WindupRuleMetadata].providersToRules[?RuleProvider][?].contextMap So I was trying to get it out, WindupRuleMetadata wrm = (WindupRuleMetadata) event.getRewriteContext().get(WindupRuleMetadata.class); Assert.assertNotNull("event.getRewriteContext()[WindupRuleMetadata.class] is not null", wrm); for(WindupRuleProvider provider : wrm.getProviders()) { if(provider.getClass().equals(TestMetadataAnnotationExecRuleProvider.class)) continue; provider.get } But here I got lost as there seems to be no API for providersToRules. 1) How can I get to the metadata? 2) I suggest to review where and how the metadata are stored and unify it a bit. Thanks, Ondra PS: I admit that I didn't look much around for some working usages of metadata as I am going to sleep, but CATEGORY seems not to be used anywhere.
