Hi,

FWIW 1, the acronym PWID is already used for pseudo wires. See for example RFC 6667. Whether that collision is a problem or not is not something I can judge.

FWIW 2, I have also not seen any earlier request to the urn@ietf.org mailing list, although I have seen the I-D posted.

However, I don't remember having seen Eld's message back then, and as far as I remember correctly we have not processed the PWID template which is an Internet draft. Eld did remind me about her request in February, and I forwarded her email to Lars, but my email archive does not tell if he responded. Be that as it may, I should have been more active in getting this review started earlier - sorry.

The draft standard shall not contain examples for URN:PWIDs as long as the URN namespace has not been formally registered. Some examples for PWIDs may however be added, since the importance of citing web archives is growing and we need not only guidelines on how to do that, but also increased stability the usage of persistent identifiers can provide.

If coverage-spec were not part of the identifier but included in r-component, it would be easier to add new functionality in the future and use similar functionality, when relevant, to other kind of resources.
