Web services open the door to FMCSA safety

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

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

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

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 4

What is XML? ¡ ¡ ¡ ¡ W 3 C 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 5

FMCSA Web Service Standards ¡ SOAP l l ¡ 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 l l Web Services Definition Language XML-based language used to describe services offered & provide a way to access those services electronically FMCSA web services 6

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

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

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

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 13

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

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

Lessons Learned ¡ ¡ ¡ XML & web services are relatively new & may require training Party generating XML should also use it We need standardized l l l ¡ ¡ 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 17

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 18

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 20
