1. Introduction
LCDM is:
General concept of data sharing and system collaboration all
through the construction lifecycle, not only execution process,
but also maintenance process of completed objects.
*LCDM: Life Cycle Data Management
Goals are:
To develop specification of data standards and information
infrastructure, on which standardized data are registered,
updated, and made effective use of, in order to promote data
standards and make information investment efficient.

2. Current Issues of Information Sharing
•Digitalization of paper base does not make business restructuring go a
long way.
•IT development and standardization are dealt with separately in different
fields, so that data linking is not smooth.

3. Solutions of Issues by LCDM System
（2/2）
•For the circulation of data, the first thing is circulation of data standards
in the form of data models.
Solution of Problem
•Then, plan to circulate data based upon circulating standards.
in Linking of Deferent
Communities
•And then, solve the problems involved in system-linking.
