Yes, that's true on tags, but this is a header field. Anyway I think you are right and storing a value other than the registered ones should not represent an error. iccDump issues a warning, but for many quality teams this is enough to spot an issue. ICC suggests to register the signature because in this way we avoid the mess of everybody using his own signature to point same thing. Registration is free of charge. So, using *nix is Ok, but registering it would assure every tool reading *nix would understand the same. > To avoid a perception of bias in favor of only large commercial platforms, > the ICC should either open the platform tag list up to registrations > in exactly the same manner as CMM's or devices, or deprecate it. I think it is open in the same manner of CMM. Ok, I will bring that to the ICC. Regards Marti -- CenturyLink Cloud: The Leader in Enterprise Cloud Services.

On the one hand, creating a floss profile that's incompatible with nonfloss software would of course be a problem for people who want to use that software. On the other hand, if some software refuses to use a profile because of a *nix platform tag, when the platform tag is purely testimonial and shouldn't be used - that could be characterized as a bug in the software. Negative primary values also result in a warning, at least when using iccToXml and so also with the icc profile dump app? Hopefully software ignores this warning. Otherwise there's no way to use a whole lot of custom camera input profiles with the softwares that validate profiles using the dump app. > > If you have any use case other than purely cosmetic I would gladly add > it but in any case we need to get *nix signature registered first. The use case could be characterized as philosophic and as reflecting reality, rather than as purely cosmetic. Linux does exist and is used to make ICC profiles and as a digital imaging platform. If the *nix signature were registered that would make more sense than the current situation. Of the four currently registered platform signatures, according to Wikipedia Taligent never made it to market and ceased development in 1998. I suspect Oracle isn't much used to make ICC profiles or as a platform for digital imaging. > Quoting Elle Stone : >> Wanting to see *nix as the platform is strictly a personal preference. This personal preference reflects philosophic concerns that perhaps are shared by some other people who use Linux. Elle -- CenturyLink Cloud: The Leader in Enterprise Cloud Services.

The testimonial header fields are used to generate statistics from e.g. the Taxi DB on http://icc.opensuse.org . Without that some interessting informations about OS collaboration and timelines would be non accessible. kind regards, Kai-Uwe -- CenturyLink Cloud: The Leader in Enterprise Cloud Services.
