Mews Profile is a working draft. The format, the stylesheet and this site are all version 0.1, which is to say I am still changing my mind about parts of it, and the spec admits as much in its first paragraph. What a given version promises is written down at mews.page/spec/0.1, and it stays there once published.
Anyone can submit an address. The page is fetched and put through both of the checks in section 9.1: it has to validate against the Mews DTD, and it has to follow the handful of rules a DTD can't express, like keeping your images on your own site and the markup under 256 KB (and preferably under 64). Pass both and your site is listed at once, by nobody's leave but the checker's.
Listed sites are looked at again every week, and one whose page stops conforming is dropped; since I hold no contact details there is nobody to warn beforehand, so submit the fixed page and it is listed again immediately. A site the checker simply can't reach gets a few days of retries before it goes, because being down over a weekend isn't the same as being wrong.
The checks say nothing whatsoever about what a site publishes, and they can't: a page about anything at all can be flawless XHTML. So if a listing here points at something abusive, write to me and it comes out.
A submission stores the address you gave, the domain it belongs to, what the checks found, and a salted hash of your IP address so that the rate limits work. The salt is replaced every month, so last month's hashes stop matching this month's, and raw addresses are never written down at all.
Submissions and results are deleted after ninety days. No cookies, nothing loaded from anywhere else, and no analytics, which given the subject matter would have been embarrassing.
The format rests on XHTML Mobile Profile 1.2, which the Open Mobile Alliance finished in March 2008 and which is still perfectly good. The stylesheet asks first for Atkinson Hyperlegible, made free for anyone to use by the Braille Institute of America, and then for Source Code Pro by Paul D. Hunt. Neither is loaded from anywhere: if you have them you see them, and if you don't, Verdana is waiting.
Bug reports, arguments about the spec, and sites that ought to be listed and aren't:
hello@mews.pageI would rather this stayed small: a format one person can implement in a weekend, a directory you can read in a single sitting, and pages that still open in 2046. If it grows much past that, something has gone wrong.
