What is uddi registry




















With these advanced search capabilities, requesters can find businesses with services of specific names or in a specific category and vice versa to find services owned by businesses that match specified criteria.

Such capabilities are not available with current UDDI search technology and these searches cannot be done without much effort. NET Server; see how to create custom categorization schemes that allow users to solve particular problems in description and discovery. The ability to attribute metadata to services registered in UDDI, and then run queries based on that metadata is absolutely central to the purpose of UDDI at both design time and run time.

NET Server. It explains how to create custom categorization schemes that allow users to solve particular problems in description and discovery Each of the properties in the bag comes from a known classification system Adorning UDDI entities with these property bags provides entities with the critical metadata and context that can be used to discover and consume them.

The corollary to adorning an entity with properties is the ability to search for that entity based on those properties. Queries are written that look for properties based on the classification scheme they are associated with.

In other words, in writing a query "to find services in the United States", one must provide not only the appropriate value that represents the United States but also the classification scheme from which that value originates. In this way, queries can be written that have contextual intelligence about the properties being searched for.

Other features make the UDDI query engine able to handle a range of scenarios. For example, queries can do an exact match of all the properties in a bag or can match just one property in a bag. Or, a query can search across bags contained in both providers and services.

Through these two parallel facilities -- adorning properties to entities and searching for entities based on well-known properties -- UDDI entities are reified. Below, the article will delve into exactly how to accomplish this Classification and typed metadata is key to the ability of UDDI to solve the problems of reification of data both in the enterprise and in the public sphere. Well-architected Web service software applications will employ UDDI as an infrastructure, taking advantage of the many possibilities of employing this complex categorization system to different entities for both design-time and run-time usage Web-services Specification to Play Key Role.

Most experts believe they will do that through repositories based on a specification called universal description and discovery interface UDDI. In addition to helping users and applications find specific Web services, UDDI will allow them to query data that describes how those services are used. UDDI also specifies a set of APIs to interact with the registry and provides references on how to interface with applications. UDDI registries have basic white and yellow pages models for finding services.

Solution providers will increasingly find UDDI implemented in various forms of repositories, including application servers, middleware, databases and directories. The move coincided with the release of version 3 of the UDDI spec, which gives the standard key enterprise capabilities, such as support for XML-based security and policy management, internationalization and a subscription API that generates messages when changes are made to a UDDI repository.

And late last month, Oasis announced the formation of a technical committee that will develop the technical standards and best practices. In order for Web services to proliferate, customers and solution providers should be looking at UDDI as a key component of that infrastructure. Sutor describes it as a catch So, what will make UDDI useful? It's likely to proliferate within organizations for sharing business logic among applications.

For example, Microsoft's Kurt says, if an enterprise wants to make a change-of-address service originally built for an HR application for other apps, a UDDI registry can help internal developers, or even end users, find the software components and business rules for using those programs Gartner FirstTake. Reference: FT More than 20 major IT companies have said they will participate, including most major software infrastructure providers The unprecedented cooperation by industry participants will do much to secure widespread acceptance of UDDI, which provides a common format for enterprises to identify and link to new Web services In general, enterprises will not need UDDI initially, either behind the firewall or when they deal with trusted business partners.

Standard mechanisms need to be defined for such functions as supporting granular access, denial-of-service protection and nonrepudiation. Don Box, an architect in Microsoft Corp. I predict two years from now we won't have this conference' Box said Microsoft has been moving awfully fast with its Global XML Architecture GXA for Web services; an interoperability demonstration between IBM and Microsoft here at the conference [serves] as evidence that the technology is constantly improving Box posed the question of why Microsoft is pursuing a Web services strategy.

Microsoft has bet the company on this thing and it is our intention to make all software integration based on Web services.

Microsoft White paper at GotDotNet. It provides a standard way for organizations and individuals to distribute news on the Internet. The question of discovery and aggregation of RSS Feeds has the following requirements: 1 Programmatically publish an RSS Feed; 2 Associate metadata classification, geography, ownership, etc.

It is in meeting these requirements that UDDI serves as a solution. UDDI has a flexible classification system that can be employed to attribute those feeds with a range of different metadata in an extensible way. Feeds in UDDI has been published. The code sample provides a sample. An installable. The application is meant only as a sample and is not optimized for usage.

There is no caching of feeds, for example, in the sample application. The paper opts for a particular solution; feedback and comments on the solution are welcomed In Network World August 14, Network World Directories Newsletter.

But more and more directory vendors such as Sun, Computer Associates and Novell are tossing in the towel and simply developing UDDI front ends for their directory products rather than trying to convince the world that the UDDI repository isn't needed.

Access security was ably demonstrated by SAML recently. Specifying Web services interfaces is part of the purview of the ebXML committees. Adapting someone else's initiative is very often much more efficient and productive than re-inventing the wheel The service processes the request and returns the result. Applications obtain information about how to contact a service along with other useful data from business registries such as the Universal Description, Discovery, and Integration UDDI project, a platform-independent open framework for describing services and and businesses and integrating them via the Internet.

Currently more than companies support UDDI Paul Tremblett shows how your Java applications can contact business registries, such as UDDI, and retrieve information from them We are pleased to announce that UDDI. All members will be able to actively participate in all aspects of the specification design and development. OASIS, a global consortium that drives the development, convergence and adoption of e-business standards, will manage the future development of the UDDI specification and related activities.

Existing business registries will continue to be made available by registry operators. Under OASIS, the UDDI specification will continue to advance as a standard, and interested companies can continue to incorporate the specification into future business and software plans. UDDI also will benefit from additional expertise in shaping, developing and coordinating the fundamentals for open standards based business interoperability.

The UDDI Community is comprised of more than business and technology leaders working together to enable companies and applications to quickly, easily, and dynamically find, and use Web services. This transition delivers on the goals laid out in the UDDI project's original charter. Along with the transition, UDDI. The next step for UDDI 3. Once that is passed, the first committee meeting will happen within 45 days, he said.

The group recently submitted its third version for review. In The Register July 26, That announcement will also be made Tuesday []. Since its launch in September - the apex of the b2b, b2c and online market places boom - UDDI has seen mixed fortunes NTT Communications is expected to launch its own registry this fall.

Doubts remain, though. Hewlett-Packard Co signed an agreement to operate a registry, but that registry's future is in doubt after HP pulled out of Java middleware and web services. HP failed to return Computerwire calls for comment. Meanwhile, some early adopters are bypassing UDDI entirely.

Deloitte Consulting principal and e-business chief technology officer Michael DeBellis reports early adopters are hard-coding together web services, by-passing UDDI and defeating the vision. Anecdotal evidence says some early adopters are putting web services data into directories based on LDAP, a well-established directory technology, instead of UDDI. Observers feel UDDI is in danger of being sidelined by events.

Where it is being used is behind the firewall,' DeBellis said. The specification improves interoperability and replication between registries behind those firewalls.

In short, just as each enterprise application embodies the specific characteristics of the business process it supports, so should the enabling technologies like UDDI support a variety of infrastructural permutations. For UDDI, this business requirement dictated an increased emphasis on providing a means to define the relationships among a variety of UDDI registries, not simply access to one, public registry of business services, the UBR.

Although the UDDI specification included from the start concepts like replication and distribution among server peers, earlier definitions of the standard did not fully address the nuts-and-bolts required for the more sophisticated, hierarchical model now dictated The Version 3 specification addresses several features that support an emphasis on registry interaction.

While relatively little of the existing features have changed, a handful of key functional concepts have been added or expanded to accommodate the variety of new taxonomies. Some of the most important issues addressed in the Version 3 specification include: 1 Registration key generation and management; 2 Registration subscription API set; 3 XML digital signatures Thus, while the specification does not define specific policies around security and authorization, it does provide the means for specific implementations to provide for these needs.

The primary benefit of digital signatures is to ensure that data has not been altered since it was signed and published, that ownership of a particular registry entity can be validated, and confidence that data transferred among registries can be assured The number of public node operators has also increased from two to three, with a fourth operator expected to release its node shortly. The number of businesses registered among the three public UBR nodes recently surpassed 10, with over 4, individual Web services available.

All registered data is now being replicated between the UBR nodes. The UDDI Community is comprised of more than business and technology leaders working together to enable companies to quickly, easily, and dynamically find, and transact with one another. As a cornerstone of the emerging Web services architecture, UDDI will benefit businesses of all sizes by creating an open platform-independent specification.

As a part of the UDDI project, a global business registry has been established to allow businesses to publish and discover Web services Joint construction will begin in mid-July and operations will commence in October this year. The UDDI Project is a worldwide initiative to enable businesses, irrespective of industry, to quickly, easily and dynamically find one another, leading potentially to new business-to-business e-commerce.

UDDI enables a company to describe its business and services on the Internet, to discover other companies that offer desired services, and to negotiate and settle with those companies The UDDI Business Registry is a global public online catalog for companies to register their business and the services they offer. The registry allows a business to easily locate a supplier to meet its needs and then to negotiate and settle e-transactions.

It is a significant part of the framework supporting Web services. Today's joint announcement paves the way for commercial e-commerce expansion in the Asian region. The registry will operate in IBM's WebSphere runtime environment and will use IBM's DB2 software for data repository, thereby enabling construction of the registry system based on Web services standards It is meant to complement the UDDI tool kit available to the Java development community, and gives customers the alternative of using a different Web services development platform.

The rapid application development that the Python language provides is leveraged by any system working within the Web services arena and utilizing the UDDI4Py package. Expanding on the foundation of Versions 1 and 2, Version 3 offers the industry a specification for building flexible, interoperable XML Web services registries useful in private as well as public deployments. The Version 3 specification offers clients and implementers a comprehensive and complete blueprint of a description and discovery foundation for a diverse set of Web services architectures.

In InternetWeek June 20, Most experts still believe that UDDI will ultimately play a key role in the adoption of Web services. At its core, UDDI provides a place for businesses to describe and register -- and for other companies to discover -- the Web services interfaces they are making available to the world.

UDDI has been anything but a slam-dunk thus far. The technology hasn't been as flexible as many developers would like. And participation in public UDDI registries as been low.

But it's still early in the game. Many early UDDI server implementations were solely for proof-of-concept. Also, many early servers were public deployments, while much of the early work with Web services turned out not to be over the public Internet but behind corporate firewalls.

But if such architectures are to scale, developers need a place to register their services so they can be easily found and consumed. Ultimately, criticizing early UDDI specifications and deployment efforts was beside the point -- the technology won't really be needed until Web services take firm hold on the enterprise landscape. Despite its early flaws, UDDI is making progress. The current, 2. Market-watchers expect additional steps forward this summer with the release of version 3.

Yet even more significantly, vendors are beginning to bring UDDI more into the enterprise mainstream. For instance, the past few weeks have seen growing amounts of activity around mapping UDDI repositories into Lightweight Directory Access Protocol LDAP directories, which in their own right have emerged as a key enabling e-business technology.

Security is already emerging as a key stumbling block for Web services deployments; existing LDAP-based authorization and access schemes can help jump-start those efforts, [Nathan] Owen said Despite the early hurdles UDDI has faced, developers still believe in the technology, according to a study released this week. According to a poll of developers by Flashline, a provider of software reuse solutions, 55 percent of respondents are currently evaluating internal or external UDDI registries, while 11 percent are already using a UDDI registry to organize access to Web services In InfoWorld June 11, The package will feature Sun's new UDDI Universal Description, Discovery, and Integration registry product for setting up registries of Web services available within a firewall or via an extranet.

Additionally, Sun on June 19 [] will detail a new version of its Java-based application server, also part of the developer platform. With the Sun ONE Developer Platform, the company seeks to solve the problem of isolated "silos" of development in an enterprise It ships in six to eight weeks. It features a plug-in to the Studio product and ships this summer.

Sun is integrating its application server into the Solaris OS. Sun ONE Studio is available in three configurations, including the free Mobile and Community editions, for mobile application and Java servlet development, respectively, and the full-fledged Enterprise Edition, supporting Enterprise JavaBeans and Web services Novell, of Provo, Utah, is interested in the UDDI Advisory Group as part of the company's effort to solidify the role of directories in Web services, the company said Novell has been making moves in this area recently.

Winston Bumpus, director of standards for Novell, said in a statement that the adoption of UDDI 'is essential in order to realize the promise of Web services -- not only to support dynamic transactions among businesses but also to enable seamless integration within the enterprise' In InfoWorld June 04, These questions are being pondered as the Web services directory specification continues to evolve.

Adoption rates have not skyrocketed as some expected, prompting many to re-examine where UDDI will fit into the Web services puzzle. The UDDI standard is intended to provide central directories where consumers of Web services can access various services, either within a company's firewall, via an extranet, or on the public Internet.

Companies can set up these registries internally and choose to extend access to partners. Associates of uddi. Security issues also will be addressed. Members of uddi. A request for proposal document has been published and sent to a selective number of standards development organizations, Munter said The product is available free for download and testing.

The spike occurred, Manes said, because Web services have begun to reach 'critical mass,' which may bode well for future adoption of UDDI This point expands on Andrew's comment about the difference between relational information and hierarchical organization.

You can also create your own taxonomies. You use these taxonomies to search UDDI Updates the version 00 draft of February Reference: 'draft-bergeson-uddi-ldap-schema May, , expires November, It defines schema elements to represent a businessEntity, a businessService, a bindingTemplate, a tModel, and a publisherAssertion The information that makes up a registration in UDDI consists of these five data structure types.

This division by information type provides simple partitions to assist in the rapid location and understanding of the different information that makes up a registration.

A businessEntity object contains one or more unique businessService objects. Similarly, individual businessService objects contain specific instances of bindingTemplate, which in turn contains information that includes pointers to specific instances of tModel objects.

It is important to note that no single instance of a core schema type is ever "contained" by more than one parent instance. This means that only one specific businessEntity object identified by its unique key value will ever contain or be used to express information about a specific instance of a businessService object also identified by its own unique key value Category: Informational. February, , 19 pages. It is important to note that no single instance of a core schema type is ever 'contained' by more than one parent instance.

In Software Development Magazine April Colan acknowledged that the public UDDI registry is 'very hit or miss. Despite his evangelical role, Colan doesn't think the registry will truly become useful until , the year he believes "we'll really get serious" about Web services.

According to Colan, you could use UDDI behind your firewall, for example, enabling employees to search within the company for internal or approved service providers and automate transactions beyond current intranet approaches In InfoWorld May 02, UDDI Universal Description, Discovery, and Integration is an industry standard for development of Web services registries, to be deployed either privately within company firewalls or publicly The product, however, is 'certainly something that could [also] be deployed in a public manner,' added Struble, who is a Sun delegate to uddi.

Sun recently re-branded several software product lines under the Sun ONE umbrella, including its iPlanet offerings, which feature software such as Web and portal servers. Sun with its UDDI and Web services efforts may be getting a bit ahead of the market, according to one analyst Sun has no plans to set up a UDDI node for registering publicly available Web services, as some other vendors have done, according to Struble In InfoWorld April 26, UDDI is designed to provide registries, either public or private, for registering and discovering Web services.

Panelists from uddi. The concept is still maturing, said panelist Joel Munter, senior software engineer at Intel, following comments from panel moderator Brent Sleeper, a consultant at Stencil Group, about registries allegedly 'missing in action' and scant services being available. Many Sun customers still are thinking about using UDDI internally first before considering utilizing public registries, she said. UDDI is well-positioned for use within firewalls, she said.

UDDI, he added, can be used for business-to-business integration, enterprise application creation, and for developing a network of business partners In April 22, UDDI 2. The UDDI 2. First, Version 2. This is especially important for large organizations with many divisions or subsidiaries that will register themselves in a UDDI directory Second, UDDI 2.

If the Publish to Registry option is enabled, the proxy services are published as soon as they are created or edited and the session is activated. You can use the Publish to Registry option with all proxy services, except those using the Local Transport. You can automatically publish proxy services to the default UDDI registry that you configure for a session. In order to enable automatic publishing, you need to enable auto-publishing on the service and you need to define the default UDDI registry so Service Bus knows which UDDI registry to publish services to.

For more information about editing proxy services, see Configuring Proxy Services. You can only publish services to a UDDI registry when you are not in a session. Exit your session to enable UDDI publishing and access the registries list.

By default, all proxy services in the session are selected. Clear the check boxes for any services you do not want to export. The Publish Summary page appears, and indicates whether the services were published successfully. It also lists any messages generated during the publishing process. On the Destination page of the Import from UDDI dialog, select the project or folder where you want to import the service and then click Next.

A list of matching business services appears in the Business Services table. If you are unable to find a specific service, it may be because you do not have the security permissions to view its records. If a selected service has multiple binding templates, each binding template results in a business service. The Binding Template page lets you further narrow your selection among the binding templates you want to import. The Review page appears, displaying a summary of the resources to be imported.

A warning message is displayed for any resource that cannot be imported. The selected resources appear in the Project Navigator. The Import from UDDI wizard displays a summary of the import along with any errors in the imported resources.

The import process can result in dependency issues. To view and resolve any resulting conflicts, click the Conflicts tab at the bottom of the console. The Auto-Import Status page lets you synchronize changes to a service with those present in the registry. Any service imported while automatic import is enabled is kept synchronized with the UDDI registry. Upon any changes to a service in the registry, Service Bus provides notification of the change on the Auto-Import Status page, which lists all out-of-sync services.

You can view the status of synchronized services on the Auto-Import Status page. When automatic import is enabled and there are any failures during auto-synchronization, the errors are reported on the Auto-Import Status page. After fixing the errors, you can synchronize the services manually. When you do not want the service in the Oracle Service Bus Console synchronized with the corresponding service in the registry, you can avoid synchronization by detaching it from the registry.

Unlinking a business service from the UDDI registry cannot be undone. You have to re-import the service manually to link them back up. The Auto-Import Status dialog appears.

Services are shown on this page only when there is a change in the original service in the registry. Not every service is available on this page. This scenario illustrated using Service Bus to import services from a registry and then publish Service Bus proxy services back to the registry.

See Figure Proxy services are configured to communicate with the business services in the pipeline. The proxy services can then be published back to the registry and made available for use by other domains.

This scenario shows cross-domain deployment using Service Bus. In this scenario, a Service Bus application in one domain requires access to a Service Bus service in another domain at runtime.

An instance of Service Bus is deployed in each of two domains. The Service Bus proxy service P1 is configured in domain D1. As the domains cannot communicate directly with each other, P2 in D2 cannot use P1 in D1. The Service Bus import and export feature does not support runtime discovery of services in different domains, but publishing the service to a UDDI registry allows the discovery and use of a service in any domain.

Once P1 is made available in the UDDI registry it can be invoked at runtime for example, get a stock quote and imported as a business service in another Service Bus proxy service. When importing and exporting from different domains you should have network connectivity. A proxy service might reference schemas located in the repository of a different domain, in which case you need HTTP access to the domain to import it using the URL.

In the absence of connectivity an error message is returned. Service Bus proxy service attributes must be mapped to the data model supported by the UDDI registry to allow a proxy service to be published as a UDDI business entity.

Table shows the service types, message types, and transports relevant to the UDDI registry mapping for a proxy service. Optional parts are listed in parentheses. Messaging services can have different content for requests and responses, or can have no response at all one-way messages.

Proxy services have attributes in common and also attributes that are specifically defined by the transport protocols used by the service and the type of service. Each proxy service can deliver messages of a certain type. This document is also used as a reference point for publishing non-WSDL based services.

To publish Service Bus proxy services as entities in the UDDI registry, you must provide additional canonical tModels to support some of the constructs specific to Service Bus.

Not all attributes of a proxy service are useful when searching for a service, for example, service type and transport details.

These attributes do not categorize the service. These configuration details are mapped to the business service binding template tmodelinstanceDetails section.

Other attributes specifically identify a service and can be used as the search criteria for the service. These attributes are mapped using keyed references to tModels with values in the categoryBag of the binding template. There is a special keyedReferenceGroup for Service Bus properties. An example of a key is uddi:bea. The following example shows a mapping of high-level proxy service information to a business service.

The key for the businessService created when a proxy service is published is a publisher assigned key name. It is derived from the Service Bus domain name, the path of the proxy service, and the proxy service name.

It takes the following form:. This includes the following:. Each of the transport types in the uddi:uddi. See Table This metadata provides the configuration details of the transport for the proxy service.

It is neither useful for characterizing the service nor useful in querying the service. However, after the service has been discovered, this data is needed to access the service.
