  1. Web services open the door to FMCSA safety data Jeff Hall – FMCSA IT Project Manager Traffic Records Forum July 28, 2004

  2. Agenda • FMCSA Goal • Web service description • FMCSA web services • XML standardization • Lessons learned • Summary FMCSA web services

  3. FMCSA Data Exchange Goal • Provide data to customers • In standardized format • Using standardized method • Without human intervention • Assuring privacy of personal data FMCSA web services

  4. What is a Web Service? • Self-contained business functions that operate over a network (e.g. Internet) • Standards-based & interoperable between any two systems/platforms • Two-way communication • Application-to-application interaction without human intervention • Cheap & flexible implementation • FMCSA standard data exchange method FMCSA web services

  5. What is XML? • W3C specification (International standard) • Tagged document (like HTML) • Uses dynamic tags (unlike HTML) • Is human readable & flexible • Is interoperable between any two systems/environments • Cheap & flexible implementation • FMCSA standard data exchange format FMCSA web services

  6. FMCSA Web Service Standards • SOAP • Simple Object Access Protocol • Encodes an HTTP header and an XML file so they can be passed between two programs on different computers and know how to respond • WSDL • Web Services Definition Language • XML-based language used to describe services offered & provide a way to access those services electronically FMCSA web services

  7. Analogy – Sending a Document • Web service = Federal Express • WSDL = Next day delivery and FedEx contact information • SOAP = Box and shipping label • XML = Contents/Document FMCSA web services

  8. FMCSA Web Services • Inspection Selection System database refresh • Automatically detect status & perform refresh • Compliance Review upload • Move data up, integrate into central Oracle DB, & return confirmation or error report • Query Central data retrieval (pending) • SAFER input & output FMCSA web services

  9. Carrier Summary Carrier OOSO Carrier Details US CDL Violation Details QC MX Carrier Registration Past Inspections MX CDL Carrier Registration L&I

  10. MX SCT Query Central Data Flow FMCSA Internal Databases TML MX LIFIS State CDLIS XML Query Central Application Security Internet XML CVIEW & ITDS HTTP Web Service

  11. ID & Registration License & Insurance FMCSA Web services Privacy Restricted Data Unrestricted Data Inspection Crash VPN Encryption Public & Industry State

  12. SAFER • Safety And Fitness Electronic Records • Communication nexus for State CVIEW (Commercial Vehicle Information Exchange Window) systems • Includes • FMCSA & State past inspection database • FMCSA carrier snapshot database FMCSA web services

  13. Purpose for SAFER Web Services • Provide data not found in the local CVIEW system in real time • Upload data in real time from local CVIEW system FMCSA web services

  14. SAFER Web Services • Inspection input (beta) • Inspection summary output (soon) • IFTA input / output (planned) • IRP input / output (planned) • IRP registration input / output (beta) • Fleet input / output (planned) • Carrier e-screening input (planned) • Vehicle transponder input / output (planned) • MCMIS safety & census update (beta) • License & insurance output (soon) FMCSA web services

  15. SAFER Web Service Contacts • Jingfei Wu • wu@volpe.dot.gov • (617) 494-3796 • Andrew Wilson • andrew.wilson@volpe.dot.gov • (617) 374-2353 FMCSA web services

  16. XML Standardization Project • Standardize FMCSA XML • Vocabulary • Schemas • Includes review of existing industry & government standards • All data types included in project • Crash • Inspection • ID • Licensing & insurance FMCSA web services

  17. Lessons Learned • XML & web services are relatively new & may require training • Party generating XML should also use it • We need standardized • XML vocabularies • XML schemas & • Data dictionaries • XML/web services are cheap & flexible relative to EDI • Need standard location where FMCSA Web Services information could be accessed, including downloadable WSDL files & documentation, & a UDDI directory of Web Services FMCSA web services

  18. Summary • XML is a valuable data format for exchanging data between disparate systems • Web Services are the best method for automating the movement of data between applications over the Internet • FMCSA has standardized on both FMCSA web services

  19. References • XML. The eXtensible Markup Language (XML) Version 1.0 (Second Edition) W3C Recommendation is published by the World Wide Web Consortium at http://www.w3.org/TR/2000/REC-xml-20001006. • SOAP. The Simple Object Access Protocol (SOAP) 1.2 W3C Recommendation is published by the World Wide Web Consortium at http://www.w3.org/TR/2003/REC-soap12-part1-20030624/. • WSDL.

  20. Questions? “… XML and Web Services are becoming the language of business and that deciding not to invest and go in that direction would be similar to deciding not to invest in having a telephone number or even a web site for your business.” Neil Charney Director, Platform Strategy Group, Microsoft June, 2003 FMCSA web services
