RE: Organize a chat on account/ledger capabilities?

Hello Adrian,

Well worded response, of which I recognize quite a lot.
Some comments, though:


·         ISO standards must be paid for, but do you think the cost is prohibitive?
I think ISO has a different business model as W3C, but for ISO my organization does not have to pay a (substantial) membership fee.

·         Participation in ISO work is also possible for small companies and specialists. At least, it was when I was chairing the Dutch normalization committee for Identification cards in the nineties…

·         In my opinion, we should make use of ISO and other work as components. ISO 20022 is surely a given and could be extended with JSON formats next to XML and ASN.1. ISO 8583 is gradually on it’s way out, but we have to keep in mind that many processing systems are firmly based on this standard and migration will take 5-10 years. Other standards such as security, connectivity (NFC) are necessary elements as well.

·         The W3C WPAY must define the gaps and fill these with open standards, building on the fundaments of ISO and others. In the cards world, you could say that EMV dit that as well, athough still not as open as is the case with W3C...

Comments welcome!

Hi Kris,

I'd classify ISO 20022 as an exception. The development of the standard was done in the traditional ISO manner but the standard is just a methodology that laid a foundation for open development of the messaging standards.

Traditionally ISO standards are developed quite differently to Web standards. They are developed in closed groups under strict confidentiality and the standards themselves are not free and open for anyone to download and implement royalty-free.

The W3C (like the IEEE, ETT Internet Society etc ) are advocates of open standards principals: https://open-stand.org/ which are quite different to the principals of ISO.

That is not to say there are not reasons for there to be different approaches to standardisation for different circumstances but from the perspective of Web technology development I would strongly favour open standards.

Some illustrative anecdotes:

I worked for a long time at for a very large payments software vendor where we spent a lot of our time ensuring our software was compliant with the latest specifications. These were usually variations of ISO8583 from different networks. All of these specs were closely guarded confidential documents that required careful management of their distribution. To this day I have not seen a copy of the original ISO8583 spec from ISO because my company would have had to pay a lot of money for it just for me to have that privilege.

I am part of the W3C liaison with ISO for ISO12812 and have had to install a whole load of document lifecycle management software on my laptop just to be able to receive documents to do my work.

The reality is that the ISO model may work in manufacturing or similar industries where there are layers of abstraction from the specification to the implementation and the cost of getting your hands on the spec is minimal in comparison to all of the other input costs.

On the Web, where some products are developed with almost zero overheads on tiny budgets as they attempt to get traction this model simply doesn't work. The only people that can afford to be bothered with ISO specs are already large companies the majority of whom are struggling to innovate fast enough to defend themselves against the threat of the small start-ups (especially so in the financial technology sector).

So, I can imagine these incumbents being very supportive of ISO specifications, especially in jurisdictions where they have implicit regulatory backing, but that would simply be because it helps them maintain their defense against disruptive innovators that see proprietary and closed specifications as barriers to entry.

On ISO20022 specifically:

I think the approach taken with ISO20022 is excellent. I am certain it will become the language of payments globally and that is attributable in large parts to the availability of information on it's use. It's the only developer friendly ISO specification initiative I am aware of.

I would like it if JSON encoding was supported as a first-class citizen since that is the the most common data encoding format on the Web (I know it's possible just not easy).

I would also be interested to know if ISO20022 had picked a linked-data format (like JSON-LD) for encoding if the current plethora of message types and fields and complexity could have been avoided but who can say.

Hi Adrian,

Can you explain why you qualify ISO standards as being the opposite of open W3C standards?
I myself haven’t encountered a more open (financial) standard as ISO 20022.


Kind regards
Kris

Hi Ian,
Definitely interested. It would be great if the standards that were used for XS2A came out of this group and followed all of the open standards principles of the W3C and used Web technology as opposed to some ISO standard.
We need to get some direct participation from the EPC, EBA etc

Hi Kepeng, Pat, Adrian, Evert, Cyril, Jurgen, (and others who may be interested),

I was chatting with Kepeng yesterday about capabilities related to account/ledger access. We were discussing
the sorts of useful things one could do if there were standard APIs for account/ledger access, including building
risk monitoring systems that would have an easier time working with diverse types of accounts. Also, I wondered
whether PSD2 regulation in Europe might be leading to a need for open standards to provide access to
accounts from Web applications.

Maybe we can organize a Thursday call around this topic so that we can determine who is interested, and
whether, for example, there is even enough interest to start a task force.

Please let me know if this discussion would interest you. Thanks!

Ian
