Background(1/2) • IT development and standardization have been dealt with • separately in different fields • Realizing the importance of data management all through • the lifecycle • Establishing IT infrastructure for Japanese construction field

  4. 1. Background(2/2) LCDM Forum (First stage) • Non-profit task force led by private companies Established in Feb.2005 • Construction industry, IT industry, and public sector members • Finished two years term which was original purpose • Proposal of forum was adopted “Innovation 25 for Japanese construction field”

  5. 2. Concept of LCDM System(1/2) Apply Registration of LCDM-Standard Specification LCDM Registry Data model, Data elementdictionary, Glossary LCDM Specification Retrieve standards LCDM-Standard Specification Developer LCDM Portal Interface Information of Data Providing Systems Retrieve standards Public Sector Retrieve standards Register Interface Information Register Interface Information Retrieve standards Web Service Citizen LCDM Adapter Legacy Data LCDM Data Construction Company LCDM-StandardData users LCDM System Legacy System LCDM-Standard System Administrator Legacy System Administrator LCDM Data Providing System Register Retrieve

  6. 2. Concept of LCDM System(2/2) LCDM Registry － To make visible who, what, and where about data specification － One LCDM Registry in construction field － Registration to registry goes through human evaluation LCDM Portal － To provide data to users － Users access Portal to retrieve and obtain the data LCDM Adopter － To transform non-standard data like legacy data into LCDM-standard data

  7. 3. Operation of LCDM System(1/3) • Two Phase in LCDM System • Register phase The Registration and Maintenance Management of Information • Search phase Data Search and Data Acquisition Service

  8. 3. Operation of LCDM System(2/3) Data Standard Developer • Registering Register the Data Standard Metadata LCDM Registry Data Std.

  9. 3. Operation of LCDM System(3/3) LCDM Registry • Searching Data Standard Metadata LCDM Data Standard LCDM Portal Metadata LCDM Adopter Metadata LCDM metadata LCDM Portal(1) LCDM Data Search LCDM Portal Data (Copy) LCDM Data Search LCDM Data Acquisition LCDM Adaptor Data (Copy) LCDM Meta Data (Copy) LCDM Data Acquire User Application System LCDM Adopter Data Providing System LCDM Data

  10. 4. Data Handled by LCDM System(1/3) • LCDM Data Standard • Definition • The definition of items in Data and description form of Data • Before registered to LCDM Registry, authorized by Evaluation Authority • Requirement • LCDM Data Standard Agreement • Authorized by Evaluation Authority for LCDM Registry • LCDM Data • Definition • The Data based on LCDM Data Standard • Requirement • Created according to LCDM Data Standard • Provided by Data Providing System, and searched and acquired thorough LCDM Portal.

  11. 4. Data Handled by LCDM System(2/3) Main Metadata handled by LCDM Information Circulation Infrastructure • LCDM Data Standard Metadata • Used to create LCDM Data Standard • LCDM Portal Metadata • Used to search for LCDM Portal • LCDM Adopter Metadata • Used to search for LCDM Adaptor and get Information • LCDM Metadata • Used to search for LCDM Data provided through LCDM Adaptor

  13. 5. Solution of Issues by LCDM System • Firstly, circulate data standards in the form of data models • Then, plan to circulate data based upon circulating standards • Lastly, solve the issues involved in system integration Solution of issues in integrated different Communities Prospective Data Circulation Priority of solution of issues Emergent Data Circulation Data Standard Circulation Data Standard Circulation Data Standard Circulation Solution of issues in System integration Solution of issues in Data Solution of issues in Data Standard

  14. 6. LCDM Forum (Second stage) • LCDM Forum (Second Stage) was established in Jan.2008 . • The purpose of second stage is - to concrete vision of using standardized data by systematic platform - to promote the importance of sharing and circulating standardized data

  15. 7. Registry Prototype Background • The registry prototype has started to develop by JACIC (Japan Construction Information Center) since July of 2007. • The prototype was based on the concept of LCDM system • The purpose of prototype is to promote and to evaluate the availability of LCDM Referred Software • Omar ver.3.1

  16. Use case of Registry Prototype “LCDM Registry Prototype” UI Services Registry Core functions caseＡ UI to ManageLCDM Data Spec Services to search LCDM Data Spec • Developer of Data Spec • System Developer UI to searchLCDM Data Spec Services to manageLCDM Data Spec Data Specification Searching data Registration of data Simplified Portal • Developer of Portal case Ｂ Data providing system Simplified Portal UI user
