XML Schemas for Exchange of Transportation Data (TransXML)

The planning, design, construction, maintenance, and operation of the transportation infrastructure all require exchanging large volumes of data. Until recently, transportation agencies have been hindered by the lack of common data formats that would facilitate the exchange of data across different platforms and applications. XML (eXtensible Markup Language) has proven to be a universal structured data transfer methodology that facilitates e-Business and e-Government. Originally designed to meet the challenges of large-scale electronic publishing, XML is also playing an increasingly important role in the exchange of a wide variety of data on the web and elsewhere. XML data structures, known as schemas, provide a mechanism to develop and adopt common formats for data exchange. The XML schemas that are of interest to AASHTO and its member departments typically support transportation infrastructure-related business processes in local, state, and federal departments of transportation (DOTs) as well as the work of their partners. These schemas are of equal interest to vendors who develop software products to support the transportation industry. There are currently several open consortia of private- and public-sector organizations working to create schemas to support the transportation industry, including LandXML, aecXML, ITS XML, and OpenGIS. For some transportation applications, XML schemas do not yet exist, but their availability would facilitate the exchange of transportation data broadly across multiple business areas in a format independent of the software that produced it. However, there is no formal mechanism or framework within the transportation community to develop and maintain XML schemas, promote schema consistency and acceptance, solicit broader input, and build consensus. There is a need for development and long-term support of XML schemas for exchange of transportation data that are widely accepted, thoroughly documented, and published on the Internet for access by any organization or individual. The long-term vision is an overall set of XML schema for transportation applications in a framework to be called TransXML. The objectives of this project are to develop broadly accepted public domain XML schemas for exchange of transportation data and to develop a framework for development, validation, dissemination, and extension of current and future schemas.
