Subject: RE: [ebxml-dev] Distributive Directories ?
David, IMHO, there are real problems from a business stand point of defining a distributed directory the way that you define it. 1) Companies spend a lot of money acquiring customers. To place those customers in a common registry is a non starter. We see real problems with services like Passport that allow all participating merchants to share all customers. I think that companies will follow the customers. They will join the registries that service a specific market segment to address that market segment. 2) I have always thought that a common registry really needed a qualifying function. This function would judge the worthiness of the requestor. Maybe this would be apart of the negotiation process. One of the potential abuses that could result is competitors could query the registry for pricing information then programmatically reduce there pricing. Now this doesn't really bother me that much if all participants are aware of the activity. Perhaps special purpose registries could be set up to satisfy these market needs. In theory, this would drive market efficiency. Vendors could reposition and price products and services based on the spot price of the products and services and inventory and/or service capacity. I think that this leads to world that looks more like Farrukh's. Service providers and larger organizations will need distributed registries like Farrukh has described to handle transaction volumes and business continuity. We are seeing even in the UDDI world a need for private registries or combination private/public registries. zack -----Original Message----- From: David Lyon [mailto:firstname.lastname@example.org] Sent: Friday, April 19, 2002 1:10 AM To: email@example.com; firstname.lastname@example.org Subject: [ebxml-dev] Distributive Directories ? Andrzej, You've raised some really good points. Now I don't profess to be an expert in UDDI or WSDL but I've always liked the general philosophy behind ebXML. Generally speaking the idea of a registry is a good one, it's virtually an extension of the Trading Partner information that is kept in most of the old EDI software programs. Has anybody ever considered a Distributive Directory ? This is now possible and viable with broadband and offers advantages for small business over a centralised registry. The philosophy behind a Distributive Directory is that a company joins an Exchange and when they do their details are broadcast (name, address, net-address) to everybody on the exchange. The details of the new company are stored in the database of all the companies that are connected. The result is that within a city or region, everybody can have the contact details of everybody else and their pricelist/catalog. One could connect an entire city so that everybody could share everybody elses information. With broadband transmission speeds, a 2gig/hertz processor and a 70 gig hard drive, this seems to be readily achievable. That btw, is the hardware that the local Plumber can afford. Surely this sort of technology is on the verge of becoming a reality. There are some among us who have seen it in operation.
