LCDM 推進フォーラムに関するお問合せ先 

LCDM Forum was once resolved on February 23, 2007, but we have restarted on January 16, 2008. And it was resolved again on February 10, 2010.
The results were succeeded to Kokudo Sougou Kenkyu Kikou.

1.Organization of LCDM ( Life Cycle Data Management ) Forum
  • Non-profit task force led by private companies
  • Construction industry, IT industry, and public sector members
2.Goal of the Forum
  • Deploy information infrastructure to construction IT field
  • Realize data sharing and system collaboration all through the construction life-cycle
3.Overview of LCDM
  • LCDM is a general concept of data sharing and system collaboration all through the construction lifecycle, not only execution process, but also maintenance process of completed objects.
  • The Goals of LCDM 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.
4.Background
  • Specific non-consistent standards and systems for diverse fields of Japanese construction
  • Increase of needs for data sharing and reuse, all through the lifecycle of social infrastructures.
5.Schedule of the Forum
  • Stage 1 : Feb 2005 - Jan 2007
  • Stage 2 : Jan 2008 - Jan 2010
6.Results of Stage 2
  • You can download these specifications ( in Japanese ) from this site.
7.Standards based on
  • ISO 15836:2003(E) Information and documentation -- The Dublin Core metadata element set
  • ISO / IEC 11179 Information Technology - Metadata registries
  • UN / CEFACT Core Component Technical Specification
  • DDMS (Department of Defence Discovery Metadata Specification) Version 1.0 29 September 2003
  • and so on.
8.LCDM Concept
  • LCDM System is composed of 3 components, as follows.
  • LCDM Registry will be developed to make visible who, what, and where about data specifications. Only a single LCDM Registry may be allowed in construction field, and registration to the registry may go through human examination, to secure data interoperability.
  • LCDM Portals may be developed to provide data to users who will search and retrieve raw data from data providing systems through these portals.
  • LCDM Adapters may be developed and work as interface to transform non-standard data such as legacy data into LCDM-standard XML data.
