While XML is employed in a variety of fields, editing XML document is still hard for the beginners and ordinary individuals. In this paper, we present a syntax-directed editor which is designed to provide unprofessional XML users with easy guides of using XML document. Along with the definition, abstract syntax (data structure of syntax-directed editor) would be explicitly defined. Components of the editor will be projected according to the projected definition of the abstract syntax rule of this paper. Moreover we show that the automatic generation of the abstract syntax rules coming from DTD would enhance the use of XML syntax-directed editor in faster and more precise ways. It could be easier to generate XML syntax-directed editor through a structure of abstract syntax and standard procedure of manufacturing syntax-directed editor.

전자상거래를 위한 XML 및 관련 표준은 기존의 표준을 개선하거나 새로운 표준이 워킹 드래프트로 제안되고 있는 등 계속적으로 발전되고 있다. XML이 전자상거래에서 표준화된 문서로써 사용됨에 따라 XML문선의 효율적인 작성과 유지관리를 위해 다양한 XML에디터들이 개발되고 있다. 하지만 기존 에디터들의 경우, XML문서의 유효성만 체크하면서 단순한 편지기능만을 제공해 주고 있다. 따라서 이 논문에서는 실제 XML문서를 파싱하여 데이터베이스에 저장하고 자신이 원하는 쿼리(query)를 보냄으로써 그 결과를 XML문서로 변환하여 보여주는 기능을 구현하였다. 이는 전자 상거래 뿐만 아니라 동종 업계만의 전자 문서 교환에 있어 주고 받는 XML문서를 특별히 따로 처리할 필요 없이 원한다면 바로 자신의 데이터베이스로 파싱하여 넣거나, 필요한 부분을 기존의 데이터베이스에서 쿼리하여 이를 XML문서로 변환하여 주고 받는데 용이하게 이용될 수 있다.

웹을 기반으로 하는 분산환경에서 데이터 공유 문제를 해결하기 위해서 XML을 이용한 시스템을 등장하고 있다. 하지만, XML을 이용한 데이터 공유 및 교환은 공통된 XML DTD를 이용한 다는 것을 전제로 하기 때문에, 서로 다른 DTD를 기반으로 작성된 XML 문서는 그 의미에 대한 공유가 이루어지지 못한다. 본 논문에서는 XML 태그 및 속성을 정의하는 DTD 작성시에 데이터 레지스트리를 이용하도록 함으로써 XML 태그의 의미를 공유할 수 있는 방법을 제시하였으며, 이를 기반으로 작성된 XML 문서를 교환하고 검색할 수 있는 문서 공유 환경을 설계하였다. 제시한 환경에서 유통되는 XML 문서는 서로 다른 DTD에 의해서 작성된 경우에도 그 태그의 의미를 서로 공유할 수 있어 자동화된 데이터의 교환이 가능하며, 데이터 레지스터리에 등록된 데이터 요소의 정의를 이용해서 사용자가 원하는 개념과 일치하는 문서 및 내용을 검색함으로써, 정확한 문서 검색 결과를 얻을 수 있다.

In order to provide real-time data from sensors and instruments at manufacturing processes on web, we proposed a communication service model based on XML(eXtensible Markup Language). HTML(Hyper Text Markup Language) is inadequate for describing real-time data from manufacturing plants while it is suitable for display of non-real-time multimedia data on web. For applying XML-based web service of process data in Intranet environment, real-time performance of communication services was evaluated to provide the system design criteria. XML schema for the data presentation was proposed and its communication performance was evaluated by simulation in terms of transmission delay due to increased message length and processing delay for transformation of raw data into defined format. For transformation of raw data into XML format, we proposed two structures: one is the scheme where transformation is done at an SCC(Supervisory Control Computer) after receiving real-time data from instruments. the other is the scheme where transformation is carried out at instruments before the data are transmitted to the SCC. Performances of two structures were evaluated on a testbed under various conditions such as six packet sizes and offered loads of 20%, 50% and 80%, respectively. Test results show that proposed schemes are applicable to the systems in Ethernet 100BaseT network if total message traffic is less than 7 Mbps.

It is appropriate to use the NETCONF to monitor and manage today's complex networks that are composed of variety links and heterogeneous equipment. Since the first standard of the NETCONF are launched, there have been several revisions, but disadvantages of each layer capabilities is still present and the most typical disadvantage is XML document processing efficiency of the Content layer. In this paper, we perform data modeling by constructing a sub-tree based on the dependencies between Content layer data, and suggest method of extract efficiently data from XML by applying the extended VTD-XML technique for the XPath query. We performs experiment to compare NETCONF in proposed method to NETCONF in previous studies and NETCONF standard. we validate superiority of improved NETCONF in the paper. As experimental results, we verify that improved NETCONF is better than the other two NETCONF each 4% and 10% in terms of query processing rate, and faster than each 3.9 seconds and 10.4 seconds in terms of query processing speed.

There have been many researches for XML as the international standard to store and exchange data on the internet. Among these research fields, we focus on the techniques labeling the nodes of the XML tree that is required for querying the structural information. A labeling scheme assigns the unique label to the nodes and supports the queries for the structural information such as Ancestor-Descendant and Parent-Child relationships. In this paper, we propose a labeling scheme using vector representation where the assigned labels are not altered although XML documents are changed dynamically. Our labeling scheme reduces the storage requirement for the labels of the XML tree and provides the efficient query by using the fixed-length labels with a short size. Result of performance evaluation shows that our labeling scheme is superior to the previous approaches.

As a basic research to integrate and to retrieve XML documents efficiently, this paper proposes a clustering method by structures of XML documents. We apply an algorithm processing the many transaction data to the clustering of XML documents, which is a quite different method from the previous algorithms measuring structure similarity. Our method performs the clustering of XML documents not only using the cluster histograms that represent the distribution of items in clusters but also considering the global cluster cohesion. We compare the proposed method with the existing techniques by performing experiments. Experiments show that our method not only creates good quality clusters but also improves the processing time.

XML/EDI is different from traditional EDI because it offers the framework necessary for electronic commerce and extends the scope of the traditional EDI which focuses on data transfer. Since existing EDI services are moved to Internet platform and again to Web platform, users can use EDI in the integrated environment without inconvenience of using different EDI softwares, which have their own configurations. This paper describes the overall design and implementation of a Web-based XML/EDI system that is a core component for the electronic commerce. The constructed XML/EDI system in this paper is comprised of document generation module, document storage module, document search module, document management module, template document management module and e-mail transmission module. Requirements and design goal of XML/EDI system are introduced, detailed functionalities of modules and design facts are described and execution and execution procedures of the implemented system are explained.

This paper intends to suggest a XML-based secure E-Procurement system using Unified Modeling Language(UML), as an application system for domestic automobile industry. Applying UML methodology, which is Component-based Development (CBD), we analyzed the workflow on procurement operation of automobile industry and implemented a prototype of efficient E-Procurement system for automobile industry, by developing XML/EDI and XML signature. Also, on this paper, object-oriented CBD is employed to minimize the risk of life cycle and reuse software as mentioned to limitation of information engineering methodology. It enables the interoperability with ERP (Enterprise Resource Planning) as corporate legacy system. This system proposes a solution to apply analysis and design of workflow, component development, interoperability with corporate information system, and XML signature for integrity and authentication of electronic documents in other system so far.

Along with the developing of mobile communication technology, plenty of data transmission turn into possible in mobile environment. As the foundation, it can provide diverse mobile service. Especially the service which use electronic signature, and as the transmission of XML technology among the terminal digital signature information. By now, allowed plenty of validity confirmation questions that the digital signatures about the characteristic induced application of physical property XML. For this question, it can be solved through XML by Canonical XML 1.0 standards provided in W3C. But, because the question in the XML namespace attribute inheritance, proposed the restrictive solution. In order to solve this problem, proposes candidate plan of Canonical XML 1.1 standardized in W3C, and also even more standardization. In this paper, in order to support the widespread XML standardization in the moving environment. Standardizes Canonical XML 1.1 standard as the underlies, safeguarding the theoretical mutual identity of the XML documents, and constructing and realizing the XML standardization system.
