The multimedia community needs an environmental data representation and interchange mechanism which not only satisfies the requirements of today's systems, but can be extended to meet future data sharing needs. This mechanism must allow for the standard representation of, and access to data. The SEDRIS STF(SEDRIS Transmittal Format)provides environment data users and producers with a clearly defined interchange specification. In this paper I develop data converter commercial data(3DS MAX) format to standard interchange format and vice verse without losing semantic of information content using SEDRIS standard interchange format.

Many formats are used for recording and processing in the research of earthquake seismology and earthquake engineering. It is very difficult to program the Reading and writing algorithm for data processing because fill formats are very different from each other. It is suggested new file format of Korea Standard earthquake data (KSED) two types of ASCII and binary that are read and written easily. The Program package of basic data processing (Analyst) which has function of basic filtering spectrum analysis event gathering phase picking and location is developed In addition this program supports file transformation from another format(Mini SEED OMD K2) to KSED format.

Improved reliability of microarray data and its reproducibility lead to recent increment in demand of data sharing and utilization among laboratories, but house-keeping and publicly opened microarray experimental data can hardly be accessed and utilized since they are in heterogeneous formats according to the various experimental methods and microarray platforms. In this paper, we propose a microarray sharing method which can easily retrieve and integrate microarray data from different experiment platforms, data formats, normalization methods, and analysis methods. Our system is based on web-service technology. The biologists of each site are able to search UDDI(Universal Description, Discovery, and Integration) registry, and download microarray data with common data structure of standard format recommended by MGED(Microarray Gene Expression Databases) society. The common data structure defined in this paper consists of IDF(Investigation Design Format), ADF(Array Design Format), SDRF(Sample and Relationship Format), and EDF(Expression Data Format). These components play role as templates to integrate microarray data with various structure and can be stored in standard formats such as MAGE-ML, MAGE-TAB, and XML Schema. In addition, our system provides advanced tools of automatic microarray data submitter and file manager to manipulate local microarray data efficiently.

As digital images combined with various types of information became popular, the development of transmission format standard for effective application of imageries is demanded. The purpose of the format standard is to provide a universal format that facilitates the exchange of images and related information. In this paper, we found optimal requirements of imagery transmission format standard after reviewing current state of both military and commercial products and studying functions of various types of format standards including NITF (National Imagery Transmission Format). In addition, future research direction of the imagery transmission format standard that complies with current trend of high-resolution and mass storage imagery data is proposed.

For the space communication between a satellite and a ground station, spacecraft performs data packeting and data coding. Using standard format certainly has an advantage but depending on the hardware implementation sometimes compliance with the standard is hard to accomplish. This paper studies the suitable way to transfer image data and ancillary data to the ground station in the format of CCSDS recommendation.

The method of reusing the environmental data which is previously modelled in modeling and simulation is very important. So, we need an environmental data representation and interchange mechanism which satisfies the requirements of sharing. The SEDRIS STF(SEDRIS Transmittal Format) provides environmental data users and producers with a clearly defined interchange specification. In this paper, We design and implement an automatic converter which converts commercial data(Maya) format to standard interchange format and vice verse without losing semantic of information content using SEDRIS standard interchange format.

The objective of the paper is to recommend a database format of geographic informa¬tion systems for transportation (GIS-T) based on a review of geographic data files (GDF), a European standard format for navigation and the topologically integrated geographic encoding and referenc¬ing files (TIGER) if the USA The establishment of the standard format for transportation database is important for sharing data since data collection is costly. We believe the recommended format would reduce the implementation costs for GIS-T in Korea in the future.

This study aims to develop a standard protocol by which users can exchange data information efficiently between KOSDIC and GIS. The ultimate goal from this study is to propose a data exchange format using KOSIC. The background of this study is that GIS industry sector is vigorously developing linked to spatial information construction such as UIS, LIS, EIS, AM/FM through supporting by regional government institution. According to do, the format of data transformation becomes major issue. GIS data can easily transfer to CAD version but when CAD data convert to GIS format (DWG->DXF->SHP) cannot get high success rate due to errors and problems. In addition, CAD data feature is made from oriental structure which is made of point and line faeture so that GIS system is impossible to data transformation. In the reason, the biggest problem is discordance of symbolization in integration and standard of data format. By investigation the usability of this study, conclusion are drawn efficient alternative plan in data transformation. Though this wort we will be able to provide a better transformation of data conversion between CAD format and GIS format. Accordingly, it is of important to enrich the integrated construction information infrastructure, which accommodates ever-changing constructions environment.

The collection and manipulation of Internet of Things (IoT) data is increasing at a fast pace and its importance is recognized in every sector of our society. For efficient utilization of IoT data, the vast and varied IoT data needs to be reliable and meaningful. In this paper, we propose an IoT framework to realize this need. The IoT framework is based on a four layer IoT architecture onto which context aware computing technology is applied. If the collected IoT data is unreliable it cannot be used for its intended purpose and the whole service using the data must be abandoned. In this paper, we include techniques to remove uncertainty in the early stage of IoT data capture and collection resulting in reliable data. Since the data coming out of the various IoT devices have different formats, it is important to convert them into a standard format before further processing, We propose the RDF format to be the standard format for all IoT data. In addition, it is not feasible to process all captured Iot data from the sensor devices. In order to decide which data to process and understand, we propose to use contexts and reasoning based on these contexts. For reasoning, we propose to use standard AI and statistical techniques. We also propose an experiment environment that can be used to develop an IoT application to realize the IoT framework.

Electronic Industries Association has set a standard format called CDIF(CASE Data Interchange Format) for exchanging information between CASE tools from 1991. If data used on a CASE tool is represented in CDIF format, then any other CASE tools can use the data by translating CDlF format into their own format. In order to do so, each CASE vendor must provide a translator program from CDIF to its own data format or from its own data to CDIF format. In this thesis, we have implemented a source code generator for translating CASE data format into CDIF format only if they provide how data is stored. This automatic program generator generates CDIF statements using data format used in CASE tools, meta information about stored data and CDIF meta information. In the thesis, the automatic program generator has been implemented with Java and Oracle DBMS with JOBC interface in Sun O/S environment.
