OH, I wasn’t aware of that – but it does make sense (just as EPUB itself is under a CG).

So then to use OCF, we’d need to (just as we are talking about with EPUB 3.2) move it to a WG and REC track along with the changes.  And yes, as @Brady<mailto:duga@google.com> points out, that’s work!!

IF we wanted a ZIP-based container, which doesn’t have the problems of OCF, and is an open standard that we can refer to, then I would recommend OPC (<https://en.wikipedia.org/wiki/Open_Packaging_Conventions >), as I did in the github issue thread…OPC is used by OOXML/OpenOffice as well as ODF (MSOffice) and others.  While being an ISO standard (and thus having Ivan’s paywall concerns), it also exists as an ECMA specification which is freely available.

The IDPF submissions to W3C are CG reports and do not have status of Standard.
So, if IDPF’s OCF (now under W3C) is developed in CG, would there be some way to refer it in audio WP?

Per process this would be fairly difficult I'm afraid

OCF *is* an ISO spec: https://www.iso.org/standard/63569.html<https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.iso.org%2Fstandard%2F63569.html&data=02%7C01%7Clrosenth%40adobe.com%7C5435ab479e644b7f726b08d65f5f194e%7Cfa7b1b5a7b34438794aed2c178decee1%7C0%7C0%7C636801259392497688&sdata=0DIQBoeStXAtXCGuzZuEuYN1uR2tEkA2QT05MB7SKic%3D&reserved=0> (does ISO call them specs?)

It is also an IDPF spec. It is not a W3C recommendation. Normatively referencing an ISO spec, or a W3C recommendation should be pretty easy - just point at them. So if we want to use OCF as is, we are fine - we can point at the ISO version. If we want to make changes this becomes harder. Sure, we can make the changes (after finding editors for the document), hammer OCF into a workable W3C draft, get our two implementations, test suite, vote, etc., assuming we can get buy-in for a new ZIP based rec. None of this is impossible (well, buy in for ZIP might be), but it is not simple. There had been some comments around referencing the ISO version, but I don't see how that will be possible since we need at least one change.

I agree Brady…

But OCF is *NOT* an ISO spec, it’s an IDPF spec (see my link).  And I would assume that IDPF specs are owned nowadays by the W3C – so it’s changing a W3C spec.

But changing one thing in an ISO spec is largely as difficult as changing N things. I think the difficulty is going from N == 0 to N > 0 when it comes to changes.

Sorry I missed the meeting today, but I just reviewed the minutes (where I came up a few times 😊).

As I have previously stated, I also would support a revision to OCF (call it whatever you want) that addresses the primary issue with it today – the removal of the mandatory mimetype file.  That file and it’s requirement to be the first file in the package/archive (<http://www.idpf.org/epub/31/spec/epub-ocf.html#sec-zip-container-mime<https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.idpf.org%2Fepub%2F31%2Fspec%2Fepub-ocf.html%23sec-zip-container-mime&data=02%7C01%7Clrosenth%40adobe.com%7C5435ab479e644b7f726b08d65f5f194e%7Cfa7b1b5a7b34438794aed2c178decee1%7C0%7C0%7C636801259392507693&sdata=jOEFa8R5i0uY%2BlYeHjlkdbFP0Y42SKXHmH5mww6Nm80%3D&reserved=0>>) is the only thing that you need to change with OCF to make it usable going forward.   And just changing the MUST to a MAY is all you need to do to make it happen – it’s that simple!

Regrets.  In the air.

But, to paraphrase Trump (without yet have seen minutes for todays call [also in the air]), "I'm a zip/ocf man" (for this initial application).

Best,
