What are Web Services?

• Web services are automated server-to-server data
  exchanges over the Internet or an intranet
  typically using SOAP and transporting XML data
• Web services is a specific set of standards for
  data exchange not any service on the Web
• Sample Web service Get weather, given zip
• Web services is where XML was two years ago

Web Services Standards

• XML defines the detailed Web service data
• Web Service Definition Language (WSDL) describes
  the Web Service interface
• Simple Object Access Protocol (SOAP) transports
  Web Service information
• Universal Description, Discovery, and Integration
  (UDDI) provides a Web service directory

5
XML Web Services Benefits

• All benefits of standardized Internet
  technologies
• Lower cost, greater options, more services
• Dramatically simplified multi-media/images
• Greater flexibility for new information
  requirements, e.g. homeland security

6
Changes in Business Model

• Browser model fits better with central funding
  and management Client workstation and software
  was typically treated as local responsibility
• Organizations have evolved around technology
  changes in technology are difficult because of
  potential organizational impact

7
Message Services Evolution
Use of standard protocols brings the benefits of
competition lower costs, improved services
8
Web Services Projects

• NLETS AISLE
• RAIN Project
• Louisiana IJIS Project

9
Multi-media Web Services

• Web services image attachments
• WS-Attachment standard
• Simple Web service definition for DIME formatted
  image attachments

10
Web Services Security

• Early stages
• GLOBAL Web Services Security Task Force
  established
• Initial report with work arounds published in
  August

11
Accelerated Information Sharing for Law
Enforcement (AISLE)

• National Institute of Justice
• National Law Enforcement Telecommunication System
  (Awardee)
• Wisconsin Crime Information Bureau
• Advanced Technology Systems

12
AISLE Project Achievements

• Published the NLETS XML User Guide
• Provided full support for NLETS XML/native format
  translation at NLETS
• Provided browser based access to NLETS using XML
  Web Services in Wisconsin
• Provided full support for rap sheet XML

13
AISLE Project Strategy

• Deploy enabling TCP/IP infrastructure
• Use open standards
• Provide procurement level documentation
• Insure full legacy protocol interoperability
• Provide compatibility with industry standard
  mainframe solutions

14
XML Standards/Deployment

• Use XML with current messages while developing
  future standards

15
AISLE Project Distinctions

• AISLE supports mission critical public safety
  operations
• AISLE automates current transactions, in parallel
  with the longer consensus process for new ones
• AISLE utilizes Web Services not just XML
• AISLE Web Services greatly simplifies multi-media
  attachments in contrast to proprietary
  format/encoding

16
AISLE XML Transactions

• Simple transaction format self-defining XML
  transactions plus optional images
• Use WS-Attachment standard for images
• Transport services replaced with Web Services
• Legacy message header can precede XML
  transactions to allow legacy switch passage
