Re: [IPP] IPP Registration Request for Addition: New keywords for the "media" attribute

[Michael Sweet via ipp <[e-mail]>]

[Whew!]

All,

OK, so I've gone through ISO 1008.  The sizes there are based on the original inch measurements but are recorded in the standard as rounded millimeters, so 10x12 becomes 254x305mm vs. 254x304.8mm that an unrounded conversion would be.  Tolerances are +/-1 or 2 millimeters depending on the total length.  Given that the sizes were originally defined (and well known in) inches and the existing registered size names use the "oe" prefix and sizes in inches, I am inclined to use inches for the one ISO 1008 size (16R) that we've missed over the last 8 years since MSN2 was published rather than introduce a single ISO photo size name.

Here is a quick ASCII table of the standard numbered [0], ISO 1008, and ISO 1008-derived sizes.  I've included a notes column showing that we're previously registered other names for most of these sizes:

So, there are three sizes that HP has proposed that we have already registered (10x12, 10x15, 20x24) and a few standard photo sizes that were not included in HP's registration request.  This, combined with Christoph's observations about metric sizes yields the following updated registration:
