Representation and presentation of information in healthcare is problematic, including issues related to common formats and accessibility. XML technology infrastructure (particularly XForms and XML events) appears promising in addressing some of these issues. These technologies were investigated in the context of decision support for medication management. XForms allows rapid prototyping of information models and interfaces. XML events are useful to model simple alerts although currently limited by some components, such as date functionality.

To enhance the readability, improve the structure, and facilitate the sharing of digital imaging and communications in medicine (DICOM) files, this research proposed one kind of XML-based DICOM data format. Because XML Schema offers great flexibility for expressing constraints on the content model of elements, we used it to describe the new format, thus making it consistent with the one originally defined by DICOM. Meanwhile, such schemas can be used in the creation and validation of the XML-encoded DICOM files, acting as a standard for data transmission and sharing on the Web. Upon defining the new data format, we started with representing a single data element and further improved the whole data structure with the method of modularization. In contrast to the original format, the new one possesses better structure without loss of related information. In addition, we demonstrated the application of XSLT and XQuery. All of the advantages mentioned above resulted from this new data format.

XML data broadcast is an efficient way to deliver semistructured information in wireless mobile environment. In the literature, many approaches have been proposed to improve the performance of XML data broadcast. However, due to the appearance of wildcard "*" and double slash "//" in queries, their performance deteriorates. Consequently, in this paper, we propose a novel air indexing method called Deterministic Finite Automaton-based Index (abbreviated as DFAI) on the XPath queries. Different from existing approaches which build index based on XML documents, we propose to build the index based on the queries submitted by users. The new index treating the XPath queries with "*" or "//" as a DFA actually improves the efficiency of broadcast system significantly. We further propose an efficient compression strategy to reduce the index size of DFAI as well. Experiment results show that our new index method achieves a much better performance in terms of both access time and tuning time when compared with existing approaches.; Weiwei Sun, Peng Liu, Jingjing Wu, Yongrui Qin and Baihua Zheng

The development and verification of future GEN IV Reactor Systems is strongly related to materials data and correlated design codes. These systems are high temperature and/or corrosive media exposed. Expen-sive and extensive materials test programmes have to be launched because materials data which guarantee safe design does not yet exist for the selected materials. The costs of these extensive materials test programmes seem to be too high that they could be invested by one single GIF partner. Therefore a very important issue is data exchange between the partners to save costs and time. Within the web-enabled Mat-DB of JRC Petten an XML (eXtensible Mark-up Language) related data entry part has been installed to ease exchange of experimental materials data. This XML structure will be presented in the following as an initiative to define an internationally agreed, standardised XML schema which can be integrated in the overall MatML schema. Furthermore integrated analysis routines are implemented in the Mat-DB data retrieval part. These tools allow extra- and interpolations to calculate strain limits which are the basis for calculating safety limits against creep failure. Those safety limits are necessary elements for establishing design codes of GEN IV Reactor Systems.; JRC.F.4-Safety of future nuclear reactors

The web-enabled materials properties database MatDB of the European Commission Joint Research Centre (EC-JRC) is a database application for the storage, retrieval and evaluation of experimentally measured materials data coming from European R&D projects. Data exchange and interoperability are important database issues to reduce costs of expensive material tests. Many organizations world-wide are participating in the development of GEN IV reactors. To reduce costs the GEN IV International Forum has agreed to interoperate and exchange data for the screening and qualification of candidate materials. To simplify the complexity of data mapping between differently structured databases, adoption of a standardized XML schema is the favored option. The paper focuses on MatDB XML related tools and items: • Upgrade, extension and implementation of the MatDB XML schema within a planned US/EC cooperation; • European standardization activities for data exchange, interoperability and the development of standard formats for engineering materials data; • MatDB data cite participation.; JRC.F.4-Nuclear Reactor Integrity Assessment and Knowledge Management

Approved for public release; distribution is unlimited; New facility construction and existing facility renovation create new or modified operation and maintenance (O&M) requirements for the maintenance responsibility organization such as a Public Works Department (PWD). This O&M requirement is fully described by an Operation and Maintenance Support Information (OMSI) package. OMSI content includes facility, systems, and product information. This thesis will address information integration, the process of allowing information systems to cross-communicate and share data. OMSI information integrated within the framework of a Computer-Aided Facility Management (CAFM) system allows for early identification of O&M requirements, an improved planning capability for new facilities, and more efficient economies of scale. In addition to PWD manpower savings, OMSI-CAFM integration will also allow a revolution in the way O&M requirements are planned and created. Preliminary OMSI information would be ideally created by the design A/E after having considered work force capability from both a workload and expertise perspective. While this may be impractical due to the changing nature of workforce capability and the lengthy planning and design cycle of military construction...

The existing component protocols, as well as new protocols introduced at runtime into NPSNET-V are written in their native programming language. As a result, they require authoring and compiling by a trained programmer. The long time frame required to change or introduce new protocols into NPSNET-V, a dynamically extensible virtual environment, detracts from the dynamicism of the virtual environment. Networking optimization thresholds to support NPSNET-V needed to be determined to ensure that the networking is performed efficiently, and system resources to other systems, such as graphics rendering, are maximized. This thesis implements component protocols described using Extensible Markup Language (XML) into NPSNET-V. These protocols are created with different fidelity resolutions for each protocol, which can be swapped at runtime based on the network state. Network testing was performed to find the ideal maximum packet rates based on the impact on CPU utilization and packet loss. By using XML, non-programmers can edit protocols for inclusion in a simulation at runtime. Important contributions include adding protocols to NPSNET-V with high-resolution and low-resolution versions, described by XML documents. Basic network optimization is added to NPSNET-V to take advantage of the protocolsα resolution switching ability. The network testing revealed a linear correlation between the packet sending rate and CPU utilization...

The motivation for pursuing XML-based tactical chat includes the great potential of this technology and fixing limitations of current chat programs. XTC capabilities have the potential to completely upgrade and restructure all tactical military communications. The current tools for military chat include IRC, Yahoo, MSN, AIM, ICQ, and NKO. None of these provides the full functionality or interoperability needed in a joint environment. Moreover, if a nonproprietary chat protocol is developed, it can lead to a decision-support environment in which data, text, audio, and video can be logged, evaluated and managed, all in a Web environment where no additional specialized software or hardware is needed. Chat technology challenges for the military fit into three areas: tactical, technical, and administrative. Tactically, there are many ways chat can be used, but effective practices are not yet defined in procedures or doctrine. Joint forces use a myriad of chat programs that don’t interoperate and are usually proprietary. Technically, many chat programs are barred by firewalls and lack a robust interface to allow logging and searching past chats. From an administrative prospective, plain-text chat has no structure. Scheduling and controlling who attends or converses remains undefined. Within DoD there is no standard for how...

Approved for public release; distribution is unlimited.; This thesis addresses the issue of interoperability in DoD legacy system databases and evaluates XML as a tool for transferring message data between varied systems. With the demands for increased communication, the dire requirement for a common mode of information transfer is greatly realized. Many legacy systems have developed their own unique interfaces. XML is one solution which can help ease the transition to a common interface. This thesis is a part of a larger team effort. In contributing to this larger effort, a software program was developed to generate select messages in their native and XML formats.

For the past three decades, the Department of Defense (DoD) has used the U.S. Message Text Format (USMTF) as the primary means to exchange information and to achieve interoperability between joint and coalition forces. To more effectively exchange and share data, the Defense Information Systems Agency (DISA), the lead agency for the USMTF, is actively engaged in extending the USMTF standard with a new data sharing technology called Extensible Markup Language (XML). This work translates and synthesizes Air Tasking Order (ATO) data messages written in XML into a three-dimensional (3D) air attack plan within a virtual environment through the use of the Virtual Reality Modeling Language (VRML)

This thesis evaluates the ability of the Extensible Markup Language (XML) to address the interoperability problem that exists between Department Of Defense (DOD) legacy systems. Due to the different Database Management Systems (DBMS) used within DOD, interoperability is a major flaw. The need for communication between the DBMS within DOD is necessary and this thesis will focus on this problem. This thesis focuses in on the problems that exist, and assesses XML as a means of correcting these problems. This thesis uses the Joint Common Database (JCDB) as a means of showing XML to be a viable solution.

14th International Symposium on Unmanned Untethered Submersible Technology (UUST), Autonomous Undersea Systems Institute (AUSI), Durham New Hampshire, 21-24 August 2005; autonomous underwater vehicle (AUV) operations. In particular, missions are generally written and data archived using vehicle-specific languages and formats. Development of an unmanned vehicle (UV) ontology and automated conversion of vehiclespecific information into a data format constrained by this ontology can prove useful by enabling the development of planning and analysis tools for arbitrary vehicles and enabling facilitating interoperability between dissimilar vehicles. Implementation of this ontology using the Extensible Markup Language (XML) is the obvious choice, in part because of the ease with which it can be transformed to other formats using the Extensible Stylesheet Language for Transformations (XSLT). Additionally, consistent mappings of output telemetry to XML files permits results to be selfdocumenting and self-validating. Nevertheless, automated conversion of vehicle-specific data to a common XML format can be problematic necessitating the development of conversion methodologies suited to this task.

Current autonomous vehicle interoperability is limited by vehicle-specific data formats and support systems. Until a standardized approach to autonomous vehicle command and control is adopted, true interoperability will remain elusive. This work explores the applicability of a data model supporting arbitrary vehicles using the Extensible Markup Language (XML). An exemplar, the Autonomous Vehicle Command Language (AVCL), encapsulates behavior-scripted mission definition, goalbased mission definition, inter-vehicle communication, and mission results. Broad applicability is obtained through the development of a behavior set capturing arbitrary vehicle activities, and automated conversion of AVCL to and from vehicle-specific formats. The former uses task-level behaviors suitable for mission scripting and goal decomposition. Translations use the Extensible Stylesheet Language for Transformation, XML data binding, context-free language parsing, and artificial intelligence machine learning and search techniques. Translation capability is demonstrated through mappings of AVCL to and from multiple vehicle-specific formats. A final demonstration of the power of a common autonomous vehicle data model is provided by the implementation of a hybrid control architecture. The model's vehicle-independence and the ability to generate vehicle-specific data are leveraged in the design of an architecture that provides increased autonomy by augmenting a vehicle's existing controller. The utility of this architecture is demonstrated through implementation on the Naval Postgraduate School's ARIES Unmanned Underwater Vehicle.; US Navy (USN) author.

Generic programming has evolved at fast pace in recent years. There now exist numerous programming languages that support genericity, and generic libraries were developed that range from small utility libraries to huge general purpose or domain specific libraries. The importance of specification and verification was further emphasized in the context of generic algorithms and data structures, which became major issues in the research community. The largest generic code base is available in C++ which plays a central role for generic programming, because the Standard Template Library (STL) was implemented in C++. The STL ignited the application of its underlying principles to other domains, resulting in influential C++ libraries like the Matrix Template Library (MTL) or the Boost Graph Library (BGL). Other C++ libraries like the Matrix Template Library (MTL) or the Boost Graph Library (GPL) applied the same principles underlying the STL. This thesis deals with a problem that became apparent for languages like C++, Ada, or Modula-3 that support genericity with heterogeneous data and code representation, especially with regard to large generic libraries. These libraries cannot be compiled and distributed without their source code. Application programs using generic libraries will have to compile the occurring instantiations of generic constructs from the libraries' source code repeatedly during their development cycle. We first present a general approach to overcome the conceptual problem that necessitates this practice. It mandates a strict separation of compiler front-end and back-end which are connected by a special intermediate representation. Then an overview of the GILF system is given...

The increasing amount of available semistructured data demands efficient mechanisms to store, process, and search an enormous corpus of data to encourage its global adoption. Current techniques to store semistructured documents either map them to relational databases, or use a combination of flat files and indexes. These two approaches result in a mismatch between the tree-structure of semistructured data and the access characteristics of the underlying storage devices. Furthermore, the inefficiency of XML parsing methods has slowed down the large-scale adoption of XML into actual system implementations. The recent development of lazy parsing techniques is a major step towards improving this situation, but lazy parsers still have significant drawbacks that undermine the massive adoption of XML. Once the processing (storage and parsing) issues for semistructured data have been addressed, another key challenge to leverage semistructured data is to perform effective information discovery on such data. Previous works have addressed this problem in a generic (i.e. domain independent) way, but this process can be improved if knowledge about the specific domain is taken into consideration. This dissertation had two general goals: The first goal was to devise novel techniques to efficiently store and process semistructured documents. This goal had two specific aims: We proposed a method for storing semistructured documents that maps the physical characteristics of the documents to the geometrical layout of hard drives. We developed a Double-Lazy Parser for semistructured documents which introduces lazy behavior in both the pre-parsing and progressive parsing phases of the standard Document Object Model's parsing mechanism. The second goal was to construct a user-friendly and efficient engine for performing Information Discovery over domain-specific semistructured documents. This goal also had two aims: We presented a framework that exploits the domain-specific knowledge to improve the quality of the information discovery process by incorporating domain ontologies. We also proposed meaningful evaluation metrics to compare the results of search systems over semistructured documents.

In this paper, the authors describe a methodology to transform programmatically structured reporting (SR) templates defined by the Digital Imaging and Communications for Medicine (DICOM) standard into an XML schema representation. Such schemas can be used in the creation and validation of XML-encoded SR documents that use templates. Templates are a means to put additional constraints on an SR document to promote common formats for specific reporting applications or domains. As the use of templates becomes more widespread in the production of SR documents, it is important to ensure validity of such documents. The work described in this paper is an extension of the authors' previous work on XML schema representation for DICOM SR. Therefore, this paper inherits and partially modifies the structure defined in the earlier work.

Diverse data sets have become key building blocks of translational biomedical research. Data types captured and referenced by sophisticated research studies include high throughput genomic and proteomic data, laboratory data, data from imagery, and outcome data. In this paper, the authors present the application of an XML-based data management system to support integration of data from disparate data sources and large data sets. This system facilitates management of XML schemas and on-demand creation and management of XML databases that conform to these schemas. They illustrate the use of this system in an application for genotype–phenotype correlation analyses. This application implements a method of phenotype–genotype correlation based on phylogenetic optimization of large data sets of mouse SNPs and phenotypic data. The application workflow requires the management and integration of genomic information and phenotypic data from external data repositories and from the results of phenotype–genotype correlation analyses. Our implementation supports the process of carrying out a complex workflow that includes large-scale phylogenetic tree optimizations and application of Maddison's concentrated changes test to large phylogenetic tree data sets. The data management system also allows collaborators to share data in a uniform way and supports complex queries that target data sets.

Different models have been recently proposed for representing temporal data, tracking historical information, and recovering the state of the document as of any given time, in XML documents. After presenting an abstract model for temporal XML, we discuss the problem of the validation of the temporal constraints imposed by this model. We first review the problem of checking and fixing isolated temporal inconsistencies. Then, we move on to study validation of a document when many temporal inconsistencies of different kinds are present. We study the conditions that allow to treat each inconsistency isolated from the rest, and give the corresponding proofs. These properties are intended to be the basis of efficient algorithms for checking temporal consistency in XML.
