Pete Resnick has entered the following ballot position for draft-ietf-appsawg-json-merge-patch-06: Yes When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) Please refer to http://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: http://datatracker.ietf.org/doc/draft-ietf-appsawg-json-merge-patch/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- My previous DISCUSS asked for some textual description of the pseudocode. It turns out that the WG attempted that and was unable to come up with something clear enough to produce interoperable implementations. That's a bummer, but I am willing to take the WG's word that they tried. I will only suggest adding some text after the pseudocode to assist folks in noticing some of the "interesting" aspects of the patch procedure: Note: This algorithm has some results that might not be immediately obvious to the implementer: - If the Patch is not itself an object, the Patch replaces the entire contents of the Target. - The Patch can only affect the entire value of a member of a Target object. In particular, a Patch cannot change members of an array; it can only replace or delete the entire array. If the WG thinks there are other things worth mentioning, it might help the implementer. As I said previously, it did take me re-reading the pseudocode several times to truly understand the semantics, and if an implementer needs to structure their code differently than the pseudocode, it would be nice to point out some possibly tricky bits.
