4. 1.Introduction The B2B system is now widely used.
But it is limited to regular transactions.
However, SOAP,UDDI and WSDL has enabled world wide business transactions. But, we think, not enough.
Because ,
It is difficult to find a Web service that we want to use、
to know how to use it、
and to make client program for executing a Web service.

5. A GUI for retrieval (IBM UDDI registry)
Business name
But,we must find a Web service through the information on the window.

6. So, we developed a proto-type system to confirm the merits and demerits of this technology.
This proto-type system is a procurement system for food and beverage distribution.

7. The make up of the Web service
Web service is the distributed processing technology on the Web.
XML is used for data exchange.

2. System model
I will present an overview of this system.To demonstrate a practical case, we assume a procurement system dealing with distribution of goods between a wholesaler, retailers and manufacturers. We propose one additional database, which acts dynamically to help identify Web services. The grocery association manages the database and assists the wholesaler to find manufacturers and Web services.

10. There is a problem.
It is difficult for a wholesaler to find a new supplier by directly retrieving from the UDDI registry.
So, we assume the grocery association will help the wholesaler to find the new manufacturer.

11. ３. System function and database structure 3.1 Wholesaler
I will explain this system in detail. The wholesaler stores the order to the ”order” table. Next, the wholesaler retrieves the “Manufacturer” table using “JAN code” and confirms stock using manufacturer’s Web service .

And if there are no problems,

“PriceAndAvailable” is executed to confirm stock.

As the available stock is sufficient, “RequestOrder” is executed to make an order. And,

16. Order service : “RequestOrder”
“RequestOrder” method updates the “ReceivingOrder” and “Wholesaler” table.

17. If, out of stock or insufficient stock available,
The wholesaler must find a manufacturer that can supply the goods.
There are two ways.
One is to retrieve directly from the UDDI registry.
b. The other is to ask the grocery association to find the supplier.

18. It is not easy to find a supplier.
Direct retrieval from the UDDI registry
We developed several retrieval programs by using UDDI4J.
We can retrieve by using “name” (this means “business name”) or “description” in the “businessEntity” tag.
But,
It is not easy to find a supplier.

19. b. The assistance of the grocery association
We assumed that the grocery association provides the manufacturer’s information to help the wholesaler to retrieve useful data from the UDDI registry, and to execute manufacturer’s Web service.
That is, in advance,
The grocery association must already have the maker’s information.

20. 3.3 Grocery association Web service : “RegistrarService” two methods :
Maker retrieval service :
“findMakerByProductCode”
Presentation service of company information :
“getMakerDetail”

21. Case : Out of stock
In this example, they are short of beer. Ordered quantity is 7200bottles and
There are only 4800bottles available. So, to make good the shortfall (2400bottles), the wholesaler searches for a beer maker.
ordered quantity
stock quantity
>
All available stock is ordered by using “RequestOrder” method.

22. This is the current order status.
Beer is insufficient, so a status mark is ”△“.

23. Next, the wholesaler retrieves a beer maker with the assistance of the grocery association.

“findMakerByProductCode” is executed. And,

This maker produces the needs to make goods the shortage. So,

28. The wholesaler confirms the stock for this temporary business connection.
“PriceAndAvailable” method is executed.

29. This is a result of stock quotation from the temporary business connection.
There are sufficient stocks and price is reasonable, so the wholesaler makes an order.

Shortage　quantity
“RequestOrder” is executed.

30. This is the final order status.
After ordering, the status mark changes to a circle.

31. 4.Conclusion
The UDDI registry is the core of Web service’s technology.
But in practice, it is difficult to quickly discover necessary Web services from the UDDI registry.
important
We can easily find Web services, that we really need.

32. The Semantic UDDI registry
We introduced the concept of a business association like the grocery association to complement the UDDI registry.
For unity and consistency, it is not so good that we need other database to act as middlemen.
So, as Next step
The Semantic UDDI registry
