    3. Agenda What are XML & web services? XML examples Web services examples SAFER/CVISN Issues & lessons learned Summary

    4. 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 FMCSA standard data exchange format XML Extensible Markup Language is a tagged file or document, similar to HTML. However, unlike HTML, the creator defines an unlimited number of tags. The file is human readable and is interoperable between any two systems, meaning XML is database independent. Data is stored within the document as defined by the tags. XML is a subset of SGML. XML Extensible Markup Language is a tagged file or document, similar to HTML.

    6. What is a Web Service? Self-contained business functions that operate over a network (e.g. Internet) Emerging technology for exchanging information Standards based and interoperable between any two systems/platforms Enable application-to-application interaction without human intervention Two-way communication FMCSA standard data exchange method Web Services is an emerging technology driven by the will to securely expose business logic beyond the firewall. Through Web services companies can encapsulate existing business processes, publish them as services, search for and subscribe to other services, and exchange information throughout and beyond the enterprise. Web services will enable application-to-application e-marketplace interaction, removing the inefficiencies of human intervention.

    7. Query Central (QC) Secure information retrieval via the Internet Single input retrieves data from multiple sources (replaces stovepipe systems) Data from authoritative source in real time Provides data analysis & summarization External data retrieved in XML format Data specific to inspections & investigations

    11. Motor Carrier Profile Originally an ASCII text report Replaced in 2002 with two documents Adobe Acrobat (.pdf) document for reading XML document for analysis XML document provides ability to analyze profile data (ProVu)

    12. FMCSA Web Services Inspection Selection System database refresh Automatically detect status & perform refresh CAPRI review upload to MCMIS Move data up, integrate into central Oracle DB, and return confirmation or error report FMCSA (QC) / Customs (ITDS/ACE) interface for southern border pre-clearance and clearance Driver, vehicle, & carrier data sent to QC, checked against multiple data sources, return pass/fail

    13. SAFER/CVISN SAFER 4.2 supports XML data format FTP data transfer method Volpe CVIEW XML Certification available Reference - SAFER 4.2 ICD XML documentation http://www.jhuapl.edu/cvisn/downdocs/safer.html

    15. Lessons Learned XML and web services are relatively new and require training on both sides of any transaction Party generating XML should also use it Coordination is key to success We need standardized XML vocabularies Important to include an XML schema and data dictionary XML/web services are cheap and flexible relative to EDI

    16. 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
