In electronic commerce, a registry is an integrated software system that supports access to registry metadata in order to locate and retrieve registered objects it can be discovered and used by a client or customer. In general, a registry consists of information model and its service. A registry implementation supports a registry services interface that can be used by abstract agents to assist a human or some other software process to register new objects, provide appropriate metadata for those objects, browse or query registry content, filter out irrelevant references, and retrieve the content of selected items. We show a layered registry architecture that is flexible enough to support the required specialization of many different kinds of registry specification of other sponsoring groups. This architecture could easily adopt different registry specification. This paper suggests a prototype implementation model which supports ebXML Registry standard based on this layered architecture.

ebXML is the international technical framework specification that enables Internet-based B2B electronic business using XML, It was standardized by UN/CEFACT and OASIS on May 2001. Registry and Repository is the core of ebXML. It supports registry services which is composed of object management service and object query management service. The object management service manages the object's life cycle and the object query management service provides a mechanism to approach metadata of stored objects. Up to now, implementations of ebXML Registry object query management system don't support full functions of the specification completely. We implemented all the functions of ebXML Registry Service Specification vl.0. This system supports Browse ＆ Drilldown Query, Filter Query, SQL Query, and Object Retrieval Query services. And it also supports Content-based Query service which is not specified in the ebXML RS specification. The Content-based Query service is a repository service which makes it possible In pose content based queries of repository items and which will be specified on the RS specification v2.0.

The Sensor Registry System(SRS) provides sensor metadata to a user for instant use and seamless interpretation of sensor data in a heterogeneous sensor network environment. The existing sensor registry system cannot provide sensor metadata in case that the network connection is not available or is unstable. To resolve the problem, this paper proposes an extension of sensor registry system using network coverage information. The extended system sends a set of sensor metadata to the user by using network coverage open data (mobile vendors, signal strength, communication type). The extended SRS proposed in this paper supports a safer sensor metadata provision than the existing SRS, and it thus improves the quality of application services.

The sensor registry system has been proposed to interpret and process semantics of sensor data independently of heterogeneous sensor networks. However, the existing sensor registry system provides the static processing method. In other words, the existing system reduces the overall performance because it executes unnecessary operations and does not consider data scope to be used. To resolve the problem of the existing sensor registry system, this paper proposes a performance enhancement model based on sensor metadata reusability and scoping. The proposed model in this paper provides a function that can decide a proper scope of sensor metadata from the sensor registry system. The proposed model improves the overall performance by providing reusability of sensor metadata. This paper also shows the advantages of the proposed model through the comparative performance evaluation.

With the spread of Internet, e-business using Internet technology is being actively developed and operated. Currently, on behalf of the international e-business framework, International standard such as ebXML and Web Service is being advanced. We are able to publish and search business information through ebXML and Web Service and then actual trading between partners is accomplished. By the way, it is Registry that play an important part in e-business. Registry is an e-business infrastructure for enabling building, deploying, and the discovery of business Information. We can do e-business through Registries dynamically and share the resources. Representatives of Registry are ebXML and UDDI used as an international standard. We will meet with some problems when using Registries. ebXML Is focused on B2B collaborations and Web Service Is focused on application integrations. So we must use ebXML and Web Service characteristically, and sometimes use all at need. ebXML and Web Service contain business information by Registry specific way. So When using the services offered by ebXML and Web Service, we should access each Registry by using Registry specific tools. This thesis intended to integrate business information from ebXML Registry and UDDI Registry to accomplish e-business conveniently This thesis defined the common data model as well as integrated query language for integrated access to ebXML and Web Service along with design and implementation of the system.

The Windows registry is a hierarchical database where the configuration data of a system or application programs is stored. In this paper, we presented and implemented a registry virtualization algorithm and measured its performance. The registry virtualization algorithm presented in the paper is called Copy-One-level On Write-Open(COOWO) that is a modified version of general Copy On Whte(COW) method to make it suitable for registry virtualization. In this paper, we implemented the proposed algorithm as a dynamically loadable library in Windows and applied it to many Windows application programs. This paper is meaningful since we described a registry virtualization algorithm in detail in situation where we can not find papers that describe the registry virtualization in detail, and we could find the performance of the algorithm can be used in the real applications.

Recent web environment needs a web service method that can integrate the individual web service. The UDDI registry can accommodate this need by classifying the information of the web service system for an easy retrieval of the information, thus it reduces the time to find a specific web service. Using the basic information search function of the UDDI registry, the web provider can offer various types of information to the client. In this paper, we implemented the process of registering the information to the UDDI registry and retrieving the various types of information from the UDDI registry in a given format.

Many metadata registry management systems have been developed, which are based on ISO/IEC ll179. However, they do not follow the international standard, ISO/IEC ll179 nor provide some of mandatory functions. It is difficult to a develop metadata registry management system for domestic environment because of their hidden implementations. The goals of this paper are to solve the problems of the existing systems and to develop a metadata registry management systems for accumulation of primitive technologies. This paper also shows the metadata registry building process for the science and technology information field using the developed system. This system consists of Metadata Registry Layer, Core Component Layer, Extension Layer, and Service Interface Layer. The developed metadata registry management system follows ISO/IEC ll179 and contains mandatory functions for practical use. Therefore, it can be used as a guideline for building metadata registries and a development process of metadata registry management systems. We can easily reuse its components for development of metadata registry management systems in various fields because the system is designed and implemented based on the component-based development methodology. It also decreases time and cost for developing systems.

A registry is a hierarchy database which is designed to store information necessary for operating system and application programs in Windows operating system, and it is involved in all activities such as booting, logging, service execution, application execution, and user behavior. Digital forensic is widely used. In recent years, malicious codes have penetrated into systems in a way that is not recognized by the user, and valuable information is leaked or stolen, causing financial damages. Therefore, this study proposes a method to detect malicious code by using a shareware application without using expensive digital forensic program, so as to analysis hacking methods and prevent hacking damage in advance.

Earthquakes and volcanic information can vary in type and extent, from raw data to processed data. In order to be able to analyzed and modeled, information needs to be opened in any formats and provided with metadata from the Korea Meteorological Agency and related data production organizations. We propose the metadata and data registry related to volcanic disasters in a form that can be used in conjunction with the Korea Meteorological Administration system that manages earthquake and volcanic data in Korea. The standard registry refers to a virtual system that checks the standards developed for over 20 years in the field of geographic information and receives information registration to grasp the location of geographical features. It is not only data from natural disasters such as earthquakes and volcanoes, but also national environmental survey results, and the cooperation system with other organizations dealing with national land information is also important, so a registry that creates and operates standards is necessary. Therefore, creating and operating the standard registry is necessary and expected to contribute to academic openness and data-driven policy.
