UDDI

• UDDI Universal Description, Discovery, and
  Integration
• UDDI provides three basic functions
• - Publish How the provider of a Web service
  registers itself.
• - Find How an application finds a particular
  Web service.
• - Bind How an application connects to, and
  interacts with, a Web service after it's been
  found.
• UDDI registry contains three kinds of information
• - White pages Information such as the name,
  address, telephone number, and other contact
  information of a given business.
• - Yellow pages Information that categorizes
  businesses. This is based on existing
  (non-electronic) standards
• - Green pages Technical information about
  the Web services provided by a given business.
• UDDI.org has released the UDDI Version 3
  specification.
• the vision of UDDI a "meta service" for locating
  web services by enabling robust queries against
  rich metadata
• emphasizing the interaction of private and public
  registries

4
UBR

• UBR Universal Business Registry
• provided by UDDI Operators SAP, IBM, Microsoft,
  NTT, etc.
• Replicate information over different UBRs
• Provide free publishing/searching services
• Cooperate with private registries

5
Major UBRs

• Microsoft URB
• IBM UBR
• SAP UBR
• NTT UBR (Asias first, in Japan)

6
UBRs Interface for Human Users

• Menu bar, pop up window, directions, online help,
  embedded links easy to use
• Real URB site for business
• Test UBR site for developers
• Security feature user id, password, email
  confirmation
• Responsibility agreement to sign
• -- anyone can say anything about anything

7
Microsoft UBR a Hands-on Experience

• Real UBR http//uddi.microsoft.com/
• - for real businesses
• - register
• - publish/update/change business listing and
  technical info
• - replicated in other UBRs maintained by UDDI
  Operators
• Test UBR http//test.uddi.microsoft.com/
• - for programmers
• - register
• - publish/update/change web service info
• - wont affect other web services

8
Register with Microsoft UBR

• To publish your web services at Microsoft UBR,
  you must first register with it
• How to register with Microsoft (test) UBR
• - get a .NET Passport if you dont have one
• - sign in with your .NET Passport e-mail
  address and password
• - register with MS test UBR
• - confirm email is sent to your email address
• - click on the link embedded in the email and
  the verification is done

9
Publish/Update/Change Your Business/services Info

• You can register your business/web services with
  Microsoft UBR by providing
• - Business listing
• -Technical details
• MyUDDI (system generated)
• Provider
• tMOdel

10
Provider

• Provider a party, such as a person, group, or
  business, that offers and supports a Web service
• Provider info Include
• Details owner, provider key (system generated)
• Services categorize services and provide one or
  more access points (bindings)
• Contacts human or automated resource
• Identifiers (optional) company-wide
  identification scheme (e.g. cost code or D-U-N-S
  Number) or tModel
• Categories A categorization scheme is a
  predefined set of categories If an appropriate
  categorization is not available, contact a UDDI
  Services Coordinator.
• Discovery URLs additional technical or
  descriptive information about a provider (an
  HTTP-accessible resource )
• Relationships defines a hierarchy between two
  providers, inside or outside of your enterprise,
  such as a parent-child relationship or a
  business-to-business partnership

11
Existing Categorization Schemes

• uddi-orgtypes
• uddi-orgrelationships
• ntis-govsic1987
• unspsc-orgunspsc3-1
• unspsc-orgunspsc
• microsoft-comgeoweb2000
• ntis-govnaics1997
• VS Web Service Search Categorization
• uddi-orgiso-ch31661999

12
Existing Categories

• Under each categorization scheme, there are a
  number of categories or subcategories, e.g.
• - Calendar
• - Charting
• - Collaboration
• You select the proper categories for your
• business/web services. If the category you need
  is
• not there, contact Microsoft UBR personnel.

13
tModel

• tModel typically represents a description of an
  interface and can be referenced as part of the
  binding and instance information for a service
• tModel key unique and is intended for use in
  programmatic queries only
• e.g. uuid071bedb7-c7cd-449c-a260-1634636b862a
  
• tModel name Calendar, DAML-S, etc. (can be
  searched by initial letter(s))
• Descriptions (255 characters, text only)

14
Search

• Browse/search by
• - categories
• - services
• - providers
• - tModels
• -- type one or more initial characters use as
  a wildcard character

15
What Do You Get from Search

• Outlined info about a business/web service
• Click on a specific service, youll get info
  about
• - Details tModel name, owner, tModel key
• - Identifiers
• - Categories
• - Overview document (by following a link)
• e.g. http//HERITAGE-5844F9.cegep-heritage.qc.ca
  8888/C40Exam-PartsWS-context-root/partswspk.Parts
  .WSDL

16
IBM UBR a Hands-on Experience

• Business node https//uddi.ibm.com/ubr/registry.
  html
• Test node for developers https//uddi.ibm.com/tes
  tregistry/registry.html
• Similar to Microsoft UBR
• - A UDDI Business Registry (UBR) Node
• - Development Test Site
• - Registration
• - Publish/update/change
• - Search
• -- by business, service, technical
  model
• -- select categories
• -- provide start with (initial
  letters), value
• - Search result
• -- key, name, description, owner,
  access point (s)

17
My Experience of Using Microsoft IBM UBRs

• Detailed direction about how to publish (e.g. how
  to specify provider, tModel, etc.)
• Unique provider key
• Easy to search
• - Various ways of search by category or by
  initial letters of a
• (service, provider, tModel) name
• - Browse by category
• Result displayed with links
• Businesses/services replicated in major UBRs
• (e.g. search traffic in both Microsoft UBR
  and IBM UBR, youll get
• services with the name California Highway
  Conditions and traffic )
• Not too many services listed
• Some dont have detailed information
• IBM UBR is extremely slow these days
• --- on the whole, satisfied as a human user

18
UBRs Interface for Machines (Programmers)

• Similarities
• - functionalities for registering, publishing
  and searching business/service info
• - packages/libraries to ease the programming
  job
• Differences
• - languages (C, Java, etc.)
• - toolkits
• - incorporated with vendor-specific technologies

19
Microsoft UBRs Interface for Programmers

• Microsofts two public UDDI nodes are accessible
  through the UDDI Programmers' API
• The Microsoft UDDI Software Development Kit
  (SDK) enables client applications to interact
  programmatically at a high level of abstraction
  with UDDI registry servers that support version 2
  of the UDDI specification.
• SDK includes
• - the Microsoft UDDI managed assembly
• - comprehensive documentation
• - sample applications
• - the UDDI Publish Wizard enabling publishing
  of Web service details to UDDI from within Visual
  Studio .NET 2003.
• The SDK is designed to be used from
• - Visual Studio
• - .NET 2003 or
• - Visual Studio 6.0.
• This SDK is available as part of the Windows Core
  SDK within the Platform SDK.

20
Sample code (C) Getting Detailed tModel
Information

• using System
• using Microsoft.Uddi
• using Microsoft.Uddi.TModels
• public class GetMyTmodelDetails
• public static void Main(string args)
• try
• // Create a connection to the UDDI server that is
  to be accessed. UddiConnection myConn new
  UddiConnection("http//test.uddi.microsoft.com/inq
  uire")
• // Create an object to get the details for a
  specific tModel.
• GetTModelDetail gt new GetTModelDetail("uuidac1
  04dcc-d623-452f-88a7-f8acd94d9b2b")
• // Send the GetTModelDetail request over the
  connection.
• TModelDetail tModDetail gt.Send(myConn)
• // Since a single key was provided, a single set
  of tModel details should be returned.
• foreach (TModel tMod in tModDetail.TModels)
• Console.WriteLine("tModel name "
  tMod.Name.Text)
• Console.WriteLine("Overview document description
  " tMod.OverviewDoc.Descriptions0.Text)

21
IBM UBRs Interface for Programmers UDDI4j

• an open-source Java implementation of the UDDI
  protocol (client side)
• Java class library that provides an API to
  interact with a UDDI registry.
• enabling businesses to
• (I) discover each other, and
• (II) define how they interact over the internet
  and share information in a global registry
  architecture.

22
Most Important Classes

• Classes BusinessEntity, BusinessService,
  BindingTemplate, TModel
• Business information Contained in a
  BusinessEntity object, which in turn contains
  information about
• - services
• - categories
• - contacts
• - URLs
• - other things necessary to interact with a
  given business.
• Service information Describes a group of Web
  services. Contained in a BusinessService object.
• Binding information The technical details
  necessary to invoke a Web service. Contained in
  BindingTemplate. This includes
• - URLs
• - information about method names
• - argument types, and so on.
• Specifications for services This is metadata
  about the various specifications implemented by a
  given Web service. These are called tModels in
  the UDDI specification the UDDI4J TModel object
  represents this data.

23
Sample Application Find a business in the UDDI
registry

• //creating a UDDI proxy It has all the
  methods you need to connect to a UDDI //registry,
  execute a query, and process the results
• UDDIProxy proxy new UDDIProxy()
  proxy.setInquiryURL("http//www3.ibm.com/services/
  uddi/ testregistry/inquiryapi")
  proxy.setPublishURL(
• "https//www-3.ibm.com/services/uddi/tes
  tregistry/protect/publishapi")
• //find a business in the UDDI registry the
  first is the search parameter, the
• //second is a FindQualifiers object (null in
  this example), and the third is the
• //number of matches to return (0 means return
  all matches)
• BusinessList bl proxy.find_business("S",
  null, 0)
• //iterate through the list and prints the names
  of all the businesses that match
• Vector businessInfoVector
  bl.getBusinessInfos().getBusinessInfoVector()
• for (int i 0 i i)
• BusinessInfo businessInfo
  (BusinessInfo)businessInfoVector.elementAt(i)
• System.out.println(businessInfo.getNameSt
  ring())

24
Semantic Web Where does it Fit In?

• Current usage of UBR
• - manual publication and discovery of
  businesses and web services
• - large percent of human job even when using
  programming APIs
• - machine can extract data but not information
• - extracted info not enough for making
  decisions (e.g. you find 3 web services under the
  name calendar, but how can your machine know
  which service is what you want, say, return the
  day of week given a date?)

25
Semantic Web Where does it Fit In?

• Future UBR
• - metadata generated by system when businesses
  register for their business/services
• - semantic info extracted and stored in
  database by the system when business describe
  their services
• - ontology provided for each category
