In this paper, we describe the implementation of the configuration platform (LonWare) based on Linux for LonWorks which is one of the popular standard of home control network. LonWare consists of three modules NMML, Lonware API, LonWare DB, and it provides semantically well-defined APls for application device developers to easily access and control. And, LonWare DB is not needed to be located the outside of home, so the security-safe configurator can be made.

The Conventional database management system is not applicable because of their inadequate performance and difficulty of CAD database that is dependant to hierarchical structure and to repeat accesses of large data. For effective management and easy tool integration of CAD database, hierarchy Interface System(HIS) is designed and GROCO(Graph Representation fOr Complex Objects) Model is presented. Hierarchy Interface System which is composed of two subsystems of a configurator and a converter is designed for the interface between a conventional database management system and CAD tools. GROCO Model is a directed cyclic graph having five node-types for representing semantics and supports efficiently CAD database characters having a hierarchical structure of complex objects.

For a effective management and easy tool integration of CAD database, Hierarchy interface System(HIS) was designed and GROCO(Graph Representation fOr Complex Objects) Model was presented in another my paper[10]. Hierarchy Interface System which is composed of two subsystems of a configurator and a converter is designed for the interface between a conventional database management system and CAD tools. In this paper, Version Management System is presented for supporting effective operations of HIS using GROCO model. Version Management System supports efficiently CAD database charaters having a hierarchical structure of composite objects. In Version Management System, A design evolves in discrete states through mutation and derivation for going phases of design giving rise to multiple versions. Operations and rules are provided transition between their different states. and for controlling update propagation and preventing version proliferation. Version Modeling Graph is proposed for dealing with versioning at the instance and type levels.

There is increasing demand for enterprise smartwork system by a mobile device increases in these days. Therefore, it has been suggested in the technical platform of smartwork system. But,the research of the changeable smartwork system for quick and immediate correspondence of rapidly changing business affairs is insufficient. In this paper, we propose an adaptable mobile service architecture that can be based on the construction of flexible mobile smartwork system. This adaptable mobile service architecture is possible to dynamic service connecting the adaptable service in an existing smartwork system, and the core elements of the adaptable mobile service architecture propose 'Adaptable Service Manager', 'HotSpot', and 'Configurator'. We propose the dyanmic service processs that based on These core elements. Also, we verify the feasibility through case study that develop the project management mobile service that is usable in business of enterprise. Thus, this research provides the adaptable mobile service architecture that can provide the dynamic mobile service beyond the static mobile service of the existing smartwork system for the various change business of enterprise.
