Not only Enterprise Application Integration (EAI) within a company but also business-to-business integration (B2Bi) should be achieved for companies to collaborate seamlessly through the Internet. There have been great efforts in this area of EAI and B2Bi, resulting in lots of solutions in the market. However, EAI and B2Bi systems have been designed and operated in independent platforms and environments causing a serious problem of integrating EAI and B2Bi systems. In this paper we have proposed a business integration platform for connecting EAI and B2Bi systems in a uniform architecture and also coping with changes in business environments. In the integration platform proposed in this work, collaboration processes between B2B companies can be performed using Web Services technology widely considered as B2B integration platform. Especially, we have defined basic business execution elements based on a thorough analysis of various business integration standards and developed an efficient and extensible business process engine for B2B collaboration process management. A Web-based order processing system is developed for validation of our integration platform. It is expected that the level of B2B collaboration can be enhanced using the integration platform and furthermore it will contribute to more collaborative B2B commerce.

One of the most important prerequisites for a successful software process is the collaboration and software requirements negotiation of all stakeholders in the software development process. Remote users using computer networks can negotiate software requirements by computer supported system, and can share their informations. The goal of software requirements negotiation system is an integration of all win conditions and an agreement after resolution of conflicts. The existing systems need an exclusive system and must be dependent on specific platform and network. Users must have the knowledge of all stakeholder's status and use homogeneous collaborating applications. This paper presents the Web-based software requirements negotiation system for the purpose of resolution of the existing systems' problems. The Web-based software requirements negotiation system can be driven by WinWin Spiral model, and it is based on hybrid execution method. The proposed system is validated and tested on heterogeneous environments.

Jakarta Slide is a WebDAV server developed as one of Apache projects, which supports asynchronous authoring for various contents on the server. Unfortunately, since the WebDAV protocol does not explicitly provide the workspaces for user groups, it is difficult to support complicated collaboration using Jakarta Slide. The CoSlide system is an extension of Jakarta Slide to address this problem, presenting more effective collaborative environment by providing various workspaces for group collaboration. In this paper, we describe the CoJBother Messenger for the CoSlide collaborative system. We developed CoJBother by extending the JBother messenger based on the standard Jabber protocol. To support the users and groups defined on the CoSlide system, we also extended the Jabber protocol. CoJBother shows the information on the CoSlide users and groups in addition to the standard Jabber users and groups. In particular, through CoJBother, the members of a group on CoSlide can initiate group chatting without any administrative overhead.

This paper describes the development of a web-based interference verification system in the mold design process. Although several commercial CAD systems furnish interference verification functions, those systems are very expensive and inadequate to perform collaborative works over the Internet. In this paper, an efficient and precision hybrid interference verification algorithm for the web-based interference verification system over the distributed environment has been studied. The proposed system uses lightweight CAD files produced from the optimally transformed CAD data through ACIS kernel and InterOp. Collaborators related to the development of a new product are able to verify the interference verification over the Internet without commercial CAD systems. The system reduces production cost, errors and lead-time to the market. Validity of the developed system is confirmed through case studies.

Basically within a special regional area, a regional cluster seems to be based on core competencies of individual intra-cluster companies and collaboration among them. Information infrastructure has been emphasized as on one of competitive factors of a regional cluster, and it can be organized using collaboration system architecture integrated with each company's internal systems for efficient supply chain operation. As one of technical methods to prepare the system infrastructure supporting the collaboration of companies in a regional cluster, the Web Services can be effectively used. In this paper, a collaborative information system infrastructure for a regional cluster is suggested within the scope of supply chain management. And the efficiency of the proposed alternative is appraised with the features of a regional cluster.

WebDAV(Web-based Distributed Authoring and Versioning), a protocol which supports web-based distributed authoring and versioning, provides a standard infrastructure for asynchronous collaboration on various contents through the Internet. A WebDAV property management is a function to set and manage the main information of the resources as properties, and a user property, one kind of the WebDAV properties, has the ability to be freely defined by users. This free definition of user property makes it very useful to develop web-based applications like a collaboration system based on WebDAV However, with an existing WebDAV property management scheme, there is a limit to develop various applications. This paper describes a DavUP(WebDAV User property design Protocol) protocol which extended the original WebDAV and its uti-lization which efficiently supports management of WebDAV user properties. DavUP needs the definition of the collection structure and type definition properties for an application. To do this, we added a new header md appropriated WebDAV method functions to the WebDAV protocol. To show the usefulness of DavUP protocols, we extended our DAVinci WebDAV server to support DavUP Protocols and experimentally implemented a general Open Workspace, which provides effective functions to share and exchange open data among general users, on the DAVinci.
