ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, California / In this paper we provide the motivation for a neutral instrumentation hardware abstraction language that is focused on the description and control of instrumentation systems and networks. We also describe the design approach and structure of such a language that meets the needs. The language design is described according to the three roles it must serve: (1) as a descriptive language for specifying and describing the components and configuration of an instrumentation system, (2) as a command language for issuing configuration and data commands to instrumentation hardware and (3) as a query language for requesting the current state of instrumentation hardware.

International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper describes the basic foundations of XML and the description of a JAVA-based eXtensible Markup Language (XML) prototype application being developed for the E-9A Airborne Telemetry Platform. In an effort to eliminate proprietary software and improve range safety data exchange, radar boat position data will be tagged with pre-defined XML tags prior to being transmitted from the E-9A. Ground Station software will then processes the XML-based boat position data to provided a means for ground station personnel to strip out data and distribute over the Internet. Leveraging XML for a telemetry application provides the ability to efficiently exchange telemetry data between users over the Internet and harness a web based standard with industry wide support.

International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / XML is a simple, powerful way to agree on data transfers between organizations, applications and/or computer systems. XML was originally developed to separate data content definition from the display of data on a web page. XML is based on a subset of the Standardized General Markup Language (SGML), which means XML uses a tag-based syntax similar to Hyper Text Markup Language (HTML). Whereas HTML uses fixed tags to display data, XML uses custom designed tags to describe data. XML provides a simple, standard, portable, and flexible way to transfer data between applications. This could provide a useful way to transfer telemetry attributes data between customers and systems. Currently, there is not a significant amount of support for the use of the Telemetry Attributes Transfer Standard (TMATS). Telemetry vendors still use their own formats, customers maintain their own databases, and support facilities/ranges promote the use of their own implementations. TMATS was supposed to define a common ground to transfer data definitions, but the tools to TMATS have not come about. TMATS is a well defined, structured specification that maps into XML extremely well. Even though XML is a fairly new technology, there are already many tools available to support XML parsing with more becoming available. This makes XML an excellent choice to supplement TMATS for the interchange of telemetry attribute information. This paper provides an initial attempt at defining the language and structure for an XML vocabulary of TMATS.

International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Visitors to web pages are, in most cases, restricted to viewing information the page designer has anticipated they will be interested in viewing. Many times this is adequate, but there are instances where the visitor wants the information they view to be based on selections they choose. The Air Force Research Laboratory (AFRL) Space Vehicles Directorate anticipates selected customers will have a need to view very large data sets that vary from the satellite payload to the satellite state of health1, and will require controlling what they view in an “ad hoc” manner. In response, AFRL is using Java Server Pages developed within the data center to bring interactive and dynamic web page content to these customers.

ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The focus of this paper is to describe a unified methodology for developing both internal and external data display translators between an Instrumentation Support System (ISS) format and Data Display Markup Language (DDML), a neutral language for describing data displays. The methodology includes aspects common to both ISSs that have a well documented text-based save format and those that do not, as well as aspects that are unique to each type. We will also describe the means by which an external translator can be integrated into a translator framework. Finally, we will describe how an internal translator can be integrated directly into the ISS.

ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The Instrumentation Hardware Abstraction Language (IHAL) has been developed to be a neutral language that is focused on the description and control of instrumentation systems and networks. This paper describes the various instrumentation configuration management tools we have designed that make use of IHAL’s neutral specification of instrumentation networks. We discuss the features currently present in prototypes as well as future enhancements.

Extensible Markup Language (XML) is a simple, very flexible text format derived from SGML (ISO 8879), which is a well defined, public standard. It uses plain text to encode a hierarchical set of information using verbose tags to allow the XML document to be understood without any special reader. The use of schemas in XML also allows a well defined contract describing what a single XML document means. The self-contained nature of XML and the strong contract provided by its schemas makes it useful as an archival storage format and as a means of communicating across system or organizational boundaries. As such XML is being increasingly used by businesses throughout the world. These businesses use XML as a means of storing, transmitting and (with the use of style sheets) displaying information. The simple, well defined structure of XML does present some problems when it is used by businesses and similar organizations. As it is an open, plain text based standard care must be taken when looking at security. The use of plain text with verbose tags also results in XML documents that are far larger than other means of storing the same information. This thesis focuses on the affect of the large size of XML when it is used to communicate across a network. This large size can often increase the time taken to transmit the document and we were interested to see how it could be minimized. we investigated the ways that are used to control the size of XML documents and how they are transmitted. We carefully investigated by implementing solutions on how to transmit the XML document. We then first presented a new method, called dynamic adaptive threshold transmission (DATT), in comparisons with other existing similar methods, which, under the discussed conditions, offers significant improvements in transmission times and network transmission efficiencies.

The eXtensible Markup Language (XML) has become the standard format for data exchange on the Internet, providing interoperability between different business applications. Such wide use results in large volumes of heterogeneous XML data, i.e., XML documents conforming to different schemas. Although schemas are important in many business applications, they are often missing in XML documents. In this thesis, we present a suite of algorithms that are effective in extracting schema information from a large collection of XML documents. We propose using the cost of NFA simulation to compute the Minimum Length Description to rank the inferred schema. We also studied using frequencies of the sample inputs to improve the precision of the schema extraction. Furthermore, we propose an evaluation framework to quantify the quality of the extracted schema. Experimental studies are conducted on various data sets to demonstrate the efficiency and efficacy of our approach.
