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.

ebXML은 UN/CEFACT와 OASIS가 주축으로 제정한 전자상거래 표준으로 XML 기반의 인프라를 제공하여 글로벌 e-비즈니스가 가능하도록 하는 것을 목적으로 한다. 최근 여러 ebXML 레지스트리간의 Cooperation이 중요해지면서 2003년 6월에 제정된 ebXML RIM(Registry Information Model) 버전 2.5와 ebXML RS(Registry Service) 버전 2.5 스펙**에서는 Federation, Object Relocation, Object Replication을 포함하는 레지스트리 간의 Cooperation 기능과 더불어 Content-based 질의, Event Notification, Iterative 질의와 같은 기능들이 새로 추가되었다. 따라서. 본 논문에서는 ebXML 버전 3.0 레지스트리를 구현하기 위해서 ebXML 버전 3.0 레지스트리의 시스템 구조를 설계하였으며, 버전 3.0에서 가장 중요한 기능인 Federation을 효율적으로 관리하는 방안을 분석, 설계하고 사용자가 보낸 Federation에 대한 질의를 처리하기 위한 알고리즘을 설계하였다.

ebXML and Web Services provide UDDI and ebXML registry for storing and managing the business and Service information of companies, respectively. Recently, W3C have released the OWL(Web Ontology Language) to Recommendation, and OWL-S proposed to describe the semantics of Web Services using the OWL ontologies. In this paper, we compared the OWL-S with the registry information model(RIM) of ebXML and the data structure of UDDI, and directly connect ones, which that of ebXML similar to that of UDDI; we extend the structure of the OWL to connect the rests. Consequently, our system enables to construct the ontologies of services and discover their semantics by using the information stored in the registries, and tintegrate UDDI, ebXML registry and OWL-S registry. By using the extending OWL-S documents in our system, agents can utilize for the semantic matchmaking.

The goal of this paper is to propose a way to register agents so that makes users or autonomousagents to find target agents more conveniently and efficiently. In order to achieve this goal, we first survey the key technologies such as UDDI, ebXML, FIPA DF. As the results, we designed a new agent legistry/repository system based on ebXML technologies. We introduce our agent/repository system for wide area network and describe how to use our system for agent registering and searching target agents for communications. Finally, we give an example to illustrate a typical scenario in which user receives the results from our proposed agent registry/repository system and evaluate its characteristics in terms of advantage.

As of an international standard in e-business domains, ebXML solutions are required to be tested and authenticated whether they can satisfy the conformance and interoperability requirements. In this paper, we design and implement the ebXML conformance and interoperability testing tools that observe the standard specification in conformity with ebXML Message Service v2.0, ebXML Registry Service v2.0 and ebXML CPP/A Y2.0. With this regard, our research would serve in building the verification and authentication service infrastructure for fitting standard ebXML e-business solutions with ebXML conformance and interoperability testing tools.

To facilitate the processes of e-learning resource description, discovery and reuse, e-learning objects should be appropriately described and classified using standard metadata that need to be published in a registry to reduce duplication of effort and enhance semantic interoperability. This paper describes how standard ebXML registries can be used for semantic grid computing for annotating, storing, discovering and retrieving e-learning object metadata. For semantic annotation of e-learning objects, IEEE Learning Object Metadata (LOM) is adopted as the metadata ontology. In order to support the e-learning metadata ontology in interoperable ebXML registries, a mapping scheme between LOM and ebXML Registry Information Model (RIM) is proposed. The usefulness of sharing e-learning object metadata is demonstrated by prototyping a semantic registry based on the scheme.

OASIS의 ebXML 레지스트리는 e-비즈니스 컨텐츠 및 이에 대한 표준화된 메타-데이터를 안전하게 저장 및 관리하는 정보 시스템이다. ebXML 레지스트리 내의 e-비즈니스 정보에 대한 메타-데이터의 스키마는 OASIS 표준문서에 미리 정의되어 있으며, 이를 ebXML 레지스트리 정보모델(RIM: Registry information Model)이라 한다. 한편, 전자상거래 환경에서 시맨틱 정보 처리 기술을 도입하여 보다 효율적이고 원활한 상거래를 지원하기 위한 노력의 일환으로, 기존 ebXML 레지스트리에 온톨로지 기반의 시맨틱 정보를 관리 혹은 처리하는 기능을 추가하려는 연구에 많은 관심이 집중되고 있다. 이에 본 연구에서는, OWL 시맨틱 정보 구성자(semantic construct)로 표현된 온톨로지 데이터가 ebXML 레지스트리 내에 관리될 수 있도록 새로운 ebXML 레지스트리 정보 모델, 즉 시맨틱 정보 모델(SIM: Semantic Information Model)을 제시한다. 이를 기반으로 ebXML 레지스트리 내에서 온톨로지 정보의 추론을 이용한 지능형 정보 처리가 가능해진다. 본 논문에서는 온톨로지 데이터를 위한 새로운 ebXML 레지스트리 정보 모델을 제안하며, 아울러 온톨로지 정보 추론을 활용한 지식 처리의 예를 제시한다.
