x-trans.eu, introduced by the state of Bavaria as a pilot project during the IT Summit of 2010, focuses on the practical implementation and testing of the innovative concept called Process Data Accelerator (referred to as P23R) for reporting obligations in cross-border heavy goods transportation. Building upon previous research efforts, x-trans.eu has developed a comprehensive "Transport Data Model" to automatically select and electronically transmit the required application data for a transport request in Germany or Austria based on country-specific rules. The P23R principle ensures that application data only needs to be entered once and can be utilized for multiple transport requests in different countries. Starting from 2013, the cross-border IT solution is scheduled to transition into regular operations and undergo further expansion and development within the European context.

A digital certificate according to the ITU-T standard X.509 for a Public Key Infrastructure (PKI). The current version is Version 3 (X.509v3). Such a certificate is used within a PKI to verify the identity.

xDSL is a generic term for various DSL variants that utilize telephone lines in the access area for broadband usage. The "x" represents one or two letters that characterize the specific DSL technology. If an "A" replaces the "x", it signifies asymmetric transmission with different data rates in the upstream and downstream directions. "S" represents symmetrical data rates, "I" stands for ISDN, "RA" denotes Rate Adaptive or Speed Adaptive, and so on.

XML-based eGovernment defines specialized standards for electronic data exchange in public administration. These standards, known as XÖV standards, enable seamless execution of electronic business processes. An XÖV framework has been developed to provide the basis for the development of these standards. It contains core rules designed to achieve the goals of "interoperability improvement," "cost reduction for XÖV standardization, and project risk." The XÖV framework also serves as a basis for the coordination of XÖV activities. The guidelines and project procedures described in the framework are to be applied in the technical standardization work of the public administration, especially in the development of cross-national standards. This is intended to improve and significantly advance the implementation of standardization projects.
