Hi Henrik, I'd be good with list/YYYY/MM/DD/identifier-hash (per Wordpress and in line with ISO8601 - none of that US MM/DD/YY funny stuff) added into the urls, allowing mails to be retrieved either with or without the date. (I presume the list id is optional as well but https://mailarchive.ietf.org/arch/msg/GKYUQNOssvg-JIsPfj90_YI5r9wdoesn't work as I might expect. if https://mailarchive.ietf.org/arch/msg/list/YYYY/MM/DD/ can return all emails to that list on that date, so much the better: https://mailarchive.ietf.org/arch/msg/list/YYYY/MM gives the entire month, etc. https://mailarchive.ietf.org/arch/msg/GKYUQNOssvg-JIsPfj90_YI5r9w https://mailarchive.ietf.org/arch/msg/ietf/GKYUQNOssvg-JIsPfj90_YI5r9w https://mailarchive.ietf.org/arch/msg/ietf/2016/03/20/GKYUQNOssvg-JIsPfj90_YI5r9w should return the same thing. thanks Lloyd Wood lloyd.wood@xxxxxxxxxxx http://about.me/lloydwood ----- Original Message ----- From: Henrik Levkowetz <henrik@xxxxxxxxxxxxx> To: lloyd.wood@xxxxxxxxxxx; IETF Discussion <ietf@xxxxxxxx> Sent: Monday, 21 March 2016, 21:03 Subject: Re: new ietf mail archive? permanent urls?

If not, should it be? Yes, it is. If you go and look at the message headers, you'll notice that there's even an Archived-At: header field which has that permanent url as its value. > (It's occasionally > useful to refer to emails directly, and cite text with urls, but > that doesn't look like a good choice. I mean, no date in url? > as a hint?) Good point. I think it would be rather easy to add a date hint to the permanent URL, even if I think we'd still be using just the list and hash to identify and pull out the message at the server end. The list is already in the URL (in the case of the URL above, the list identifier is the '/ietf/' part). Regards, Henrik
