摘要

The High Level Architecture (HLA) provides a solid foundation for the design and development of distributed simulations and mandates a documentation set that describes how the data must be exchanged, its accuracy, and its frequency. For many of the interactions within a distributed simulation, basic compliance with the HLA documentation is sufficient to insure that the interactions are successfully and accurately completed. However, the HLA documentation does not address issues related to data interoperability or data representation. It is in these three areas that the Extensible Markup Language (XML) can make its contribution to distributed simulation by providing an interoperable and open format for data representation; thereby, supporting data interoperability, actor migration, and data representation. XML is a meta-language that supports the customized definition of the components of the language (syntax, data types, vocabulary, and operators) needed to support the interchange of data for a particular application environment. XML provides a basis for the development of data transmission formats that are transmitter and recipient independent and that are completely self-describing and self-contained. These inherent XML capabilities permit federates to be added to a federation with a minimum of software development and with high confidence that the information will be accurately represented, transmitted, and received within the federation. In combination, the HLA provides the external documentation needed to determine the frequency, accuracy, data type, and measurement units for data and XML permits the definition of the exact sequence of data within a transmission as well as the data type in a way that hides the complexities of the transmission from both the transmitter and recipient federates. The HLA provides the high level specifications needed to support interactions; XML permits the simulation community to move to a deeper level of specification by providing data definitions and formats that are flexible, independent, and comprehensive. In the paper we address a number of topics. We will provide an introduction to XML and describe its capabilities. We will discuss in depth the potential uses of XML in simulation environments. As a counterpoint to the discussion of uses of XML, we will also discuss the things that XML can not accomplish and the tasks for which XML would be inappropriate. We conclude the paper with a brief summary and some suggestions for further exploitation of XML's capabilities.
