Due to recent development in mobile devices, the mobile device utilization and many related applications have been increasing. Most of initial applications on mobile devices just showed simple information, but now they processes huge data. However, smart devices have certain limitations in processing massive data. Especially, if the size of data increases, the speed of data processing adversely decreases, so the performance of programs also decreases. If hardware specification of the mobile devices is not enough to handle it, response time will be drastically delayed. To overcome these drawbacks, most of application running on mobile devices communicate with their servers to manage data. XML is a proper language for data communication to send and receive data between servers and mobile devices, because it defines rules of document's format and it is a textual data format and small-sized language. However, mobile devices have limitation such as memory, CPU and wireless network to process huge data and XML also takes a lot of time to communicate with servers and devices and handle data, so it could be overhead in service time. Binary XML is an alternative of performance improvement in data processing, which has XML's benefits and minimizes the XML size by binary coding. However, most of binaryXML which are used on applications don't fit on mobile applications. In this paper, we surveyed many kinds of binaryXML, compared merits and demerits to find a binaryXML for mobile applications. We propose how to use binary XML and implemented an electronic attendance system using binary XML to overcome the limitation of XML and to reduce the load of data communications between servers and devices.

In this paper, we develop a descriptor based on binary ECG conversion system that supports the conversion of a binary ECG format into XML-based HL7 aECG for the interoperability of ECG. HL7 aECG is a XML based standard for interoperability of ECG waveform. For the conversion of variety of ECG formats, we propose a binary ECG description mechanism. In order to describe binary ECG more efficiently, we develop a XML-based Binary ECG Description (BED) Language. One of the powerful features of using the XML-based ECG Description mechanism is that ECG data can read from various formats without the modification of source code of conversion system, and consequently it reduces conversion system maintenance costs.

In this study, A BED(Binary ECG description) based binary ECG conversion system is that supports the conversion of a binary ECG format into XML-based HL7 aECG for interoperability of ECG. HL7 aECG is a XML based standard lot interoperability of ECG waveform. However, it is difficult for beginners to write the BED document of binary BED conversion system in XML. We implement a BED Studio on the Java Servlet engine that allows beginners to write BED documents more easily. Our system consists of three parts: Visual Editor, Text Editor, and Format Checking Viewer. Format Checking Viewer support users to detect the format errors in the XML files, so-called BED documents, that describe the data format of the targer binary ECG file in the BED-based binary ECG conversion system, so may reduce the format errors in BED documents.

XML is the most widely used document format by advantage that self-contained for platform. So, currently the most used among other document format. but XML appeared new problem that memory and transmission. And that be used in environment a request restriction memory and fast transmission as like mobile field. Although discussion of XML binarization is going on progress. And fast Infoset configuration using XML Information Set is receiving attention that a way to lower file size of hold down a existing usage. In this paper, we designed of module using fast Infoset and PER among ASN.1 Encoding Rule for XML binarization. And we implementation of encoder constructed interlace by stage of translation from XML into binary XML.

Tactical Data Links are standardized radio communication data links for military armed forces and used to transmit and receive data. Because they are the core elements of achieving information superiority in a NCW environment, various kinds of TDL are used by the Korean armed forces. Operating various types of TDL is very helpful in getting more information; however, at the same time, it is hard to integrate and make them co-operate with other TDLs or C4ISR systems. In this paper, we propose a XML based messaging system to make various types of TDL interoperable in a NCW environment. For the messaging system between TDL and C4ISR systems, we define XML message processing interfaces and suggest binary XML for serialization to save transmission loads over constrained military communication bandwidth. Our experiment results show that the TDL message can be transformed into generalized XML data that is interoperable with other TDLs and binary XML serialization, and it saves parsing and transmission time.

In a pervasive environment, there are various applications as much as connections of various devices. In this computing environment, XML is the most suitable data representation method. XML is able to transform data for other application areas using XSLT. XML is text-based, the file size of XML document is bigger than binary data file. Therefore, XML has a disadvantage that it is hard to deal with XML in a pervasive environment. In this paper, we survey encoding methods of XML documents, and then we propose a transform method that transforms an encoded EXI format XML document into an EXI format XML document suited for other applications. Among various applications, we present a system that transforms an EXI format XHTML document into an VoiceXML document. This system can improve reusability of EXI format XML documents in a pervasive environment and it is expected to contributes utilization of EXI format XML documents.

Recently, due to the popularity and explosive growth of the Internet, the information exchange is increasing so rapidly over the Internet. Also the XML is becoming a standard as well as a major tool of data exchange on the Internet and thus we propose the new indexing technique for evaluating a path-oriented query and design and implementation of Path-oriented Query Processing System to give useful for users. In proposed indexing technique, which combined a binary trio structure with a path signature file to improve performance of XML document retrieval.

최근 멀티미디어 응용에서 XML은 메타데이터를 표현하기 위하여 그 사용량이 증가하고 있는 추세이며, 그 예로는 MPEG-7 MDS, MPEG-21등이 있다. 이러한 XML형식의 메타데이터의 크기를 줄이기 위하여 MPEG-7에서 정의한 포맷이 Binary Format for Metadata(BiM)이다. BiM은 스트리밍을 고려하여 단편화를 통한 점진적인 전송이 가능하며, 압축률이 높고 복호화에 따르는 오버헤드가 작다는 장점을 제공한다. 본 논문에서는 BiM에 대한 간단한 소개와 모바일 환경에 적합하도록 구현한 BiM 복호기의 설계 및 구현에 대하여 소개한다.구현한 복호기는 모바일 환경의 다양한 플랫폼에서의XML 파싱 모듈과 DOM 트리모듈에 대한 종속성을 제거하기 위하여, 스키마 파일의 파싱을 데스크탑에서 수행하고 이에 대한 파싱 결과를 자체 정의한 Syntax File 형식으로 복호기에 전송할 수 있도록 하였다. 또, BiM형태로 전송되는 ESG 메타데이터와 MPEG-4 LASeR 스트림에 대하여 Windows, Windows CE, embeded Linux 환경에서 정상적으로 복호화 하는 것을 확인하였다.

Recently, the magnitude of electronic data interchange (EDI) document processing for the handling of port logistics is abruptly being increased. The existing system processes EDI documents in a script mode, but due to a complicated script preparation procedure and low document processing efficiency, it cannot meet the demand as the usage flow of documents increases. In this paper, an EDI electronic document processing system was designed and implemented in a document scanner and mapper, which are binary form electronic document processing tools and do not require script files during the conversion of extensible markup language (XML)-based electronic documents. This new system has the merits of XML features during reading and writing with improved speed, usage convenience, and good portability on systems when compared to the conventional ones.

Web service in operating environment independent XML about under using, It dose so, Integration of the platform for it is different each other possibly it is doing. But XML in order to have the text data which is unnecessary plentifully with wireless Internet or the mobile communication modem in together relatively will connect frequently slow communication medium and there is a problem point which decreases the case prerequisite efficiency which the resources will use from the limited small-sized machinery and tools. Hereupon XML about under make binary the standard which reduces the size of the document from ITU-T and ISO/IEC it was under proposing with commonness, currently binary XML encoding where it is in the process of advancing standard there are Fast Infoset and Fast Schema. In this paper, implementation of Fast XML encoding system through introduction Fast Infoset algorithm and Fast Schema algorithm for web services increase performance.
