Reviewer: Ines Robles Review result: Ready Hi, I have read the draft. The document provides a description of the requirements for a profile for label interoperation. In IoT, networks and nodes, in general, have constrained resources. Related to the topic of the draft in review, several aspects should be considered from IoT point of view, such as: - Type of devices that have insufficient resources to run DNS-SD/mDNS [1] (Some running code [7]). The work in [2][3] depicts an autoconfiguration scheme for the global (or local) DNS names of IoT devices. It uses an specific DNS Name Format (unique_id.object_identifier.OID.domain_name). - Resource Directory (RD): A web entity that stores information about web resources and implements the REST interfaces for registration and lookup of resources. A mapping between CoRE Link Format attributes and DNS-Based Service Discovery aspects (mapping ins to <Instance>, Mapping rt to <ServiceType> and Domain mapping) is descripted in version 9 of RD draft [4]. - Optimization of DNS-SD: A proposal for an optimization of DNS-SD query using TXT records is descripted in [5]. - DNS Message Compression [6], implemented in uBonjour Contiki. Thus, new work (or updates) is needed to set the requirements for label interoperation in this type of environments. I understand that this is out of scope of dns-interop draft. So, what about to add in the dns-interop draft some text like: "Related to constrained environments, work is ongoing such as autoconfiguration[2], optimization of DNS-SD [5] and DNS message compression [6] that would help to get an efficient selection of labels for DNS and other resolution systems." Hope that it helps. Cheers, Ines.
