Deja vu - also for the popular JPEG-1 (ITU-T T.81¦ISO/IEC IS 10918-1) standard
JPEG (Joint Photographic Experts Group) was originally what the abbreviation says. It was neither an ITU, nor ISO/IEC group, but an informal group of experts (with about 15 core experts) from CCITT (ITU) and ISO. It operated from 1986-1993 only in an informal manner with its own rules and documentation - before the formal agreement of joint working between ITU and ISO/IEC came into force in 1993. The differences were in different policies (like patent policy - RF "baseline" and RAND "options", individual participation, not companies, countries, NBs; completely different documentation, meeting rules etc. etc., and approval by the group when the specification was finished. This was the so so-called JPEG-8 R5 Specification in 1990 which was picked up by the Independent JPEG Group (IJG) to create an Open Source Software which came out in 1991 free of charge to anybody.
The Specification then formally was brought into the ITU and ISO/IEC JTC1 respectively, and was independently approved by both parties, in the ITU in 1992 and in ISO/IEC in 1994. The standards bodies where the specification was brought in: CCITT SGVIII "New Image Communication Group" and ISO/IEC JEC1 SC29 WG10. The successor of the ISO/IEC Working Group even today calls itself as "JPEG", but this is more marketing really and not the early group, because that group is just a normal JTC1 Working Group with JTC1 policies.
The ITU and ISO standard which based entirely on the JPEG-8 R5 specification was after parallel approval and publication sold by ISO and ITU separately in their shops. The ISO version was sold both centrally by the ISO in Geneva but also by the national standardization publishers, like DIN Beuth Verlag in Germany.
Today, after almost 30 years the situation of the sell of the submitted JPEG based specification is the following:
Purchase prise for ITU-T T.81¦ISO/IEC 10918-1 standard (according to accesses to the respective online-shops):
ISO Geneva = 198 CHF
DIN Beuth Verlag in Germany = 214,60 EUR
ITU-T Geneva = 61 CHF
Those, who know how ITU publications work will now be surprised how this can be, because from the ITU Server you can normally download the ITU standards in PDF Format free format. But not for this one, because there is this "Committee" in ISO (not the technical guys in JTC1 SC29) who decide that those joint text standards with the ITU which are commercially valuable should not be given away free of charge, Though this is against the announced policy of ISO (namely to provide such joint standards free of charge after 1 year after the first publication)....
Well, the work was done by JPEG on a completely voluntary basis. They submitted the spec free of charge in a format that was already very close to the ITU/ISO joint text publication format both to ITU and ISO. And they sell it for good money. Deja vu....
You may ask, why do they do it. Very simply because this is the business model of ISO and IEC. For many ISO areas (e.g. standardization of I do not know "rubber tyres"...) this business model works well, but for ICT and especially in Open Source ICT space (like the software code of IJG) this does not work. The problem is that to change that is for them very difficult. Both ISO, IEC in Geneva and the National Standardization Organization rely to significant share on the income from sales of publications. Unfortunately, they apparently do not look into details where and how the publications came from and if the business model they follow fits also to the business model in the ICT space of today... But hopefully one day they realize this and correct it.
