Recently, BIM has attracted attention as a technology to improve the construction productivity. The BIM standards to be applied to the BIM project are necessary for using or connecting the current 2D-based drawing standards. To develop the standard for BIM-based QTO and cost, this paper focused on using QDBEx, which was applied to road project cost management and connecting QDBEx with IFC, which is the BIM data delivery format. The IFC schema was evaluated to determine if it is possible to use the converts to the QDBEx XML file. As a result, 66% of the whole was available to connect directly, and 17% was available to connect through the processing of instance. The remaining 17% was evaluated to determine if it was available to connect. In the future, improvements in the schema will be suggested based on these results.

Most of companies related to the area of B2B electronic commerce are making their efforts to innovate their existing business process into new designed process. XML-based electronic data interchange has potential to impact on reshaping the traditional EDI systems. This study intends to suggest a prototype of XML-based electronic data interchange using unified modeling language, with a case study applied in Korean automobile industry. In order to accomplish the research objectives, we employed UML as its standard modeling language, In this study, four diagramming techniques such as use case diagram, sequence diagram, class diagram, component diagram among eight modeling techniques are used for analyzing hierarchical business process. As a result of applying UML methodology, we design and develop XML/EDI applications efficiently. Our field test applied to Korean automobile industry shows that data modeling to design XML application using UML is better than existing methodologies in representing object schema of XML data and in extension and interoperability of systems.

An electric vehicle (EV) not only receives electric power from the electric vehicle supply equipment (EVSE), but it also exchanges the information regarding charging process with the power gird through the EVSE. However, the EV and EVSE communicate using the ISO/IEC 15118 standard while the EVSE and power grid communicate using the IEC 61850 standard. Therefore, the EVSE should support both the ISO/IEC 15118 and IEC 61850 standards, and provide a data mapping function between the two communication protocols so that the EV and power grid, which support different protocols, can communicate with each other throughout the charging process. In this paper, we propose a mapping method of the EVSE, which converts the ISO/IEC 15118 data to IEC 61850 and vice versa, based on the XML schema of each protocol. The proposed method converts the data using the XSL (eXtensible Stylesheet Language) method, which defines the data mapping between two XML schemas. Our approach is more flexible and easier to maintain against changes in charging scenarios and the standards than other existing approaches such as one-to-one data mapping methods.

In this study, two standard specifications such as GML (Geography Markup Language) from OGC (Open Geo-spatial Consortium, Inc.) and X3D (extensible 3D) from Web3D consortium were dealt with for a web-based 3D urban application without using commercialized tools. In the first step of this study, DEM (Digital Elevation Model) and 3D GIS data sets were converted to GML structure with attribute schema. Then, these GML elements were projected onto a common coordinate system, and they were converted to the X3D format for visualization on web browser. In this work, a 3D urban data model, as a simple framework model, is extended to a framework model having further detailed information, depending upon application levels. Conclusively, this study is to demonstrate for practical uses of GML and X3D in 3D urban application and this approach can be applied to other application domains regarding system integrators and data sharing communities on distributed environments.

The e-Navigation promoted by the International Maritime Organization is a technology that provides marine-related information necessary for ship and shore side by electronic means for marine safety, security and protecting marine environment. The IHO S-100 standard is a geospatial standard that can express various hydrographic information. Various specifications including S-101 for electronic charts are being developed. In this paper, to help developers who are interested in implementing the technology of S-100, we not only analyze the process to portray the S-100 based data but also implement a case study on S-129 under keel clearance management. The portrayal process consists of data encoding and portrayal engine. Data encoding includes generation of application schema and data set. Portrayal engine is performed by the reform of the generated data set, the XSLT processing, and then the generation of drawing instructions.

International Hydrography Organization has published S-100 Universal Hydrographic Data Model to support use of various hydrographic data for navigational safety. In the S-100 standards, it is possible to manage hydrographic data and apply various application field by introducing the concept of registry and its register. In this study, the S-100 standard based product specification in the field of maritime safety is developed by designing application schema according to general feature model defined in the S-100 standard, and feature catalogue is produced through simple registry.

A program which can produce military standard raster maps was developed. This includes the functions that classify the types of geospatial data, publish automatically based on paper map schema, and convert products with military standard raster formats. Especially, this paper presents the automatic map-publishing technique with mathematical modeling and controling the line width, color, shape that ever not used.

As the amount of data on the web increase, it is difficult to search what we want exactly. Therefore, much researches are attempted to search web resources efficiently. So, W3C established the standard that give meanings to resources on the web using RDF metadata. The RDF metadata had been mainly described a document data on the web. But it is difficult to create automatically the metadata for application programs than the document data. This paper proposes a method to use RDF metadata to search application programs. Firstly, we define RDF data model that stores the information of the application programs and RDF schema that references the RDF data model. And we design a prototype system to search application programs. This system meets expectation, getting the application to fullfill the needs of user, and has the efficiency of the searching function.

HyTime(Hypermedia/Time-based Structuring Language), an international standard language to describe hypermedia electronic documents, is used to support the synchronization between various multimedia data for hypermedia applications. To manage the HyTime documents efficiently for shared environment, the logical structure information of them should be managed by database in a systematic way. In this Paper, we design a meta-database schema of HyTime DTDs(Document Type Definition) which define the logical structure of hypermedia documents and show how to manage the meta-database schema for storing the HyTime DTDs in the object-oriented database.

Recently with the development of IT technology, the medical technology have been developed in various ways. Among them, WBAN can check the state of the patient in real time. However, the data generated by these techniques have a problem that they have heterogeneous properties depending on the type of sensors and devices. In this paper, we proposed a method using meta repository as a way to provide the sensing data of WBAN for the health care system by integrating along the HL7 standard item.
