Radek, Sorry that my 2nd comment is not correct. The module's prefix, i.e., "ptp", is used by other PTP applications (according to RFC7950, the prefix defined by a module SHOULD be used when the module is imported). If the same prefix "ptp" is used, these PTP applications don't need to change their YANG codes (i.e., always use the same prefix "ptp" to access PTP nodes), but only change a URN namespace when migrating from IETF to IEEE-1588. Thus it is more convenient for an implementation to migrate from IETF 1588 YANG to IEEE 1588 YANG. Since the IETF will transfer the development work of the 1588 YANG to IEEE-1588, it is unlikely that another new 1588 YANG module's prefix will be introduced in the IETF.
Do you have any suggestions to improve the texts?

I have reviewed it mainly from the YANG perspective, since I'm not familiar with IEEE 1588. The draft as well as the YANG module ietf-ptp@2018-09-10 are in a good shape and ready to publish. I have only 2, say, editorial notes. 1) email of Rodney Cummings in the module's contact statement misses (in contrast to emails of other authors) starting ('<') and ending ('>') tags. [YJ] Good catch, I found this inconsistence too, and we will update it in the next revision. 2) I don't see any reason for the following paragraph in the appendix A3: Under the assumptions of section A.1, the first IEEE 1588 YANG module prefix can be the same as the last IETF 1588 YANG module prefix (i.e. "ptp"), since the nodes within both YANG modules are compatible. Since the module's prefix is used only locally, it may change when the module is updated (RFC 7950, sec. 11). So the mentioned paragraph seems pointless to me (and therefore confusing for readers). [YJ] Good catch, there is a misspelling here, "prefix" should be "postfix" in A.3, it is not the "prefix" statement in the YANG. The logic is, both "ieee1588-ptp" and "ietf-ptp" have a "ptp" postfix. _______________________________________________ TICTOC mailing list [email protected] https://www.ietf.org/mailman/listinfo/tictoc _______________________________________________ TICTOC mailing list [email protected] https://www.ietf.org/mailman/listinfo/tictoc
