What is UDDI?

Universal Description Discovery andIntegration

A platform-independent, XML-based registry forbusinesses world wide to list themselves on

internet.UDDI registers and publishes Web servicedefinitions

UDDI is a directory of Web services

UDDI uses SOAP for registering anddiscovering information

Service Type

Registrations

Companies, standards bodies,and programmers populate

the registry withdescriptions of differenttypes of services

1.Marketplaces, searchengines, and business

apps query the registry todiscover services at othercompanies

3.UBR assigns a programmatically uniqueidentifier to each service and businessregistration

Business uses thisdata to facilitateeasier integration

UDDI Data Structure

UDDI describes four core types of information:businessEntityA business or organization providing services.White page.

businessServiceServices provided by an organization.Support classification using various taxonomy systems.Yellow page.

bindingTemplateTechnical information necessary to access a service.Green page.

tModel (Technical Model)Descriptions and pointers to a reusable concept, externaltechnical specifications or taxonomies.E.g., Web service type, a protocol used by Web services, acategory system.

Juddi Steps1. From the jUDDI releases page, download the latest

jUDDI v3 tomcat-bundle, or if you want an additionalbrowser then you can download the portal-bundle.

2. Unzip the bundle and start the server by runningthe bin/start.sh (use the start.bat on windows).

3. Since the UDDI v3 API is a WebServices API you caninteract with it using tools like SoapUI.Visit http://www.soapui.org/ to download SoapUI. Unzipthe SoapUI.zip and start it using /bin/soapui.sh.

4. Open your browser to http://localhost:8080/juddiv3,and save the wsdls for the security,

publish and inquiry API.

5. Import these WSDLs into a SoapUI project, and you arenow ready to use the API. See also the demo to publishand delete a business.

can automatically execute the services specified in a BPEL4WS flow. An

extension to the UDDI inquiry API specification to enable requesters to

specify the required capabilities of a service.

A distributed XML repository, based on a Peer-to-Peer infrastructure called

pXRepository for Web Service discovery. The service descriptions

are managed in a completely decentralized way. Moreover, since the basicPeer-to-Peer routing algorithm cannot be applied directly in the service

discovery process, we extend the basic Peer-to-Peer routing algorithm with

XML support, which enables pXRepository to support XPath-based

composite queries. Experimental results show that pXRepository has good

robustness and scalability.Natenapa

Information model for web service Provides specifications by an

ontology language, and hence they can be used further to discover Web

Marco Crasso

et.al, 2008[69]

A search method for Web services called WSQBE that aims at both easing

query specification and assisting discoverers by returning a short and

accurate list of candidate services.

In contrast with previous approaches, WSQBE discovery process is based on

an automatic search space reduction mechanism that makes this approach

more efficient.

Empirical evaluations of WSQBE search space reduction mechanism,

retrieval performance, processing time and memory usage, using a registry

with service descriptions

SAWSDL In the first place, the closeness among Semantic Web

administration properties, for example, inputs and yields, is assessed

utilizing Tversky's model which is taking into account ideas (classes), their

Semantic connections, and their regular and recognizing elements

(properties). Second, the calculation, not just considers administrations

inputs and yields, yet it likewise considers the usefulness of

administrations. At last, the calculation has the capacity coordinate a

Semantic Web administration demand against commercials that are

explained with ideas that are with or without a typical ontological duty. As

such, it ca assess the compare ability of ideas characterized in the setting

of distinctive ontologies.Khalid Elgazzar

6. SEMANTIC PROCESSING

Semantic services are a component of thesemantic web because they use markupwhich makes data machine-readable in a

detailed and sophisticated way (as comparedwith human-readable HTML which is usuallynot easily "understood" by computerprograms).

than incidental properties such as their name, port, or a free textdescription.

Semantic Processing of service registry Highly assured system

standards.
