Each feature should be implementable (interoperably) by some pair of implementations. 16:21:01 I was hacking together a PROV-DM "API" in Clojure, but struggled with PROV-N parsing as EBNF is so many things and not something you can just throw at a parser library without massaging first 16:22:26 Luc: TomDN can you export more features than you do now? 16:22:52 TomDN: not much sense because the app is about reconstructing provenance -- 16:22:55 q? 16:23:12 topic: cr exit 16:23:29 Luc: time to writing up the implementation report 16:23:29 that's me 16:23:47 yes 16:23:56 q+ 16:23:59 Luc: proposed authors: Dong zednik pgroth 16:24:32 q+ 16:24:34 jcheney: XML test cases: xml examples not all valid, so not all can be parsed 16:24:43 I can fix those 16:24:55 Luc: it should be possible to fix them 16:25:06 q? 16:25:17 ack pgroth
