Pete Resnick has entered the following ballot position for draft-ietf-dnssd-requirements-05: Discuss 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-dnssd-requirements/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- Procedural issue - The shepherd writeup says: (7) Has each author confirmed that any and all appropriate IPR disclosures required for full conformance with the provisions of BCP 78 and BCP 79 have already been filed. If not, explain why? The draft includes the boilerplate confirming that the document "is submitted in full conformance with the provisions of BCP 78 and BCP 79". No disclosures have been made, nor are expected to be made in an Informational requirements draft. (8) Has an IPR disclosure been filed that references this document? If so, summarize any WG discussion and conclusion regarding the IPR disclosures. No. There was an IPR disclosure made on the earlier pre-WG version of this document back in 2013. Were the authors asked whether that disclosure also applies to this version of the document? Is the WG aware of this disclosure? Did the WG discuss the disclosure? Were any concerns raised? Section 5: OLD Devices on different links may have the same mDNS name (perhaps due to vendor defaults), because link-local mDNS names are only guaranteed to be unique on a per-link basis. Also, even devices that are on the same link may have similar-looking names, such as one device with the name "Bill" and another device using the similar- looking name "Bi11" (using the digit "1" in place of the letter "l"). This may lead to a local label disambiguation problem between presented results. SSD should support rich internationalized labels within Service Instance Names, as DNS-SD/mDNS does today. SSD must not negatively impact the global DNS namespace or infrastructure. The part about name collisions is fine, and should be said. The part about disambiguating similar characters is a rat's nest I really think you need to avoid. We can discuss this further, but the i18n community is dealing with this issue right now and it's a mess you really don't want to get into. I think you should simply stick to something like this: NEW Devices on different links may have the same mDNS name (perhaps due to vendor defaults), because link-local mDNS names are only guaranteed to be unique on a per-link basis. SSD needs to deal with name collisions beyond local link considerations. SSD should support rich internationalized labels within Service Instance Names, as DNS-SD/mDNS does today and should look to work in using internationalize strings in application protocols [soon-to-be-RFC-draft-ietf-precis-framework]. SSD must not negatively impact the global DNS namespace or infrastructure.
