Subject: RE: Summary of XML Datatypes as required for B2B applications
At UCC we provide UN/EDIFACT and X12 EDI support for our members' supply chains. Through tour work we contribute to such global efforts as the Global Data Alignment Specifications (GDAS) and GEDI data dictionaries. We are also building a bridge for our member companies to cross from EDI and manual transactions to XML. We support all members, whether they exchange information with EDI-enabled buyers or smaller SMEs not currently using EDI. We also expect to support our members with a global standard. Therefore, out position is that the EDI data dictionaries, in essence, repositories of business process, are of immense value as input into the XML standards process. In fact, we reuse this EDI knowledge in our XML effort, as you can see in the UCC Electronic commerce attachments with this mailing. However, the EDI knowledge should not be the only input to the process . Because of our history of working with our members on EDI industry standards, we know we must adhere to two principles when we define the XML standards roadmap for our members: 1. accomodate the business needs, and 2. standards do not drive business behavior, but accommodate business behavior. The EDI inputs are not sufficient by themselves to describe the business landscape of tomorrow. Converting EDI to XML in n number of days is possible, but not enough to accomodate business behavior. That is why the UCC program consists of 1. a business model represented in UML which is developed with the business community; 2. a data dictionary which is based on EDI knowledge but is not a one-for-one map of EDI to XML; 3. a set of XML metadata which is derived from 1. and 2. and the resultant XML schema. We would like to see the ebXML Core Components define a documented set of standard of core components in XML, down to the level of the document, "Using XML Schemas to define B2B Datatypes", so that we could comply to these core component definitions. I'm contributing a draft of the UML model, data dictionary and schemas of a business process that we are currently working on with our members where we address our member needs for synchronizing product and service information between buyers and suppliers. Both business needs and EDI knowledge have been useful in gathering the information. We also have work-in-progress in other areas, such as pricing, markets, purchasing. Standard, agreed upon core components from ebXML would facilitate the ease of adopting these XML transactions for our members.

But small business simply cannot afford transaction connectivity having any component of labor cost. Ian, you said "conversion of EDIFACT dictionaries" would not be difficult; please provide a definitive example, into an XML DTD or schema that would be useful for small business, in the exchange of business messages. EDI requires human negotiation and setup, causing costs for users, and revenues for EDI vendors. Does EDI have a suitable unambiguous subset? Does EDIFACT provide definitions of semantic meanings or business process? Does EDIFACT imply any consistent data model, cleansed of overlapping synonyms, duplicated structures, and collisions? Small business has no choice but to wait, and do NOTHING, until transaction cost of ecommerce comes way down. That might happen via XML if an unambiguous vocabulary emerges from ebXML. Or, it might happen within various commercial portals, Microsoft, Checkfree, AOL, etc. Right now the SMEs continue printing and mailing their checks and invoices, biding their time. The commercial companies are *miles ahead* of anything on this ebXML list. Every day you waste, the commercial companies sign up 100,000 more people and their unit costs go down, and their rent-collecting models take firmer root. For example, X.Com/PayPal has gone from zero to 1,000,000 users in the last 4 months, Respectfully, Todd Boyle Ian Galbraith said Sunday, April 16, 2000 8:34 AM on the ebXML Core Components list, and XML/EDI Group Re: Summary of XML Datatypes as required for B2B applications > Oh William, how right you are!

Because that wouldn't save non-EDI users any time or trouble, and there are hundreds of millions of non-EDI consumers and small businesses in the developed countries who need to conduct business over the internet. EDI has had its chance but the numeric codes and secret terms like MEA, CUX and DTM are never going to make it. Rescue yourself before all of EDI goes down the tubes: Spin off a subset that is more acceptable to the broader public. That's what SGML did. Look what happend to X.500. The whole wide internet has such a *hopelessly* large range of users that the perimeter of common vocabulary is going to be smaller. There is a mathematical law at work, like when you draw 1,000 circles on a venn diagram. You are not going to satisfy a large percentage of the needs of all users, like you did with EDI. With EDI you would create another 100 elements and satisfy in another 5% of the needs. This is a different game with a long tail: once you get up around 500 elements, you only get another 1% of the needs from another 100 elements so it's hardly worth the trouble. Accordingly the game is less fun but it is a lot easier: just identify 300 or 400 core elements, and quit. The form of the new XML could be very simple and obvious. It would need to provide for extensibility but the core vocabulary is something you could launch in 30 days out of the common denominators between EDIFACT and the existing XML vocabularies.
