Development and Operation of JACIC/LCDM Registry

The Ministry of Land, Infrastructure, Transport and Tourism of Japan has led the CALS/EC initiative to introduce ICT in public works since 1996. In line with the CALS/EC initiative, documents, plans and data associated with public works are to be delivered in digital form which is called as 'e-delivery'. Therefore huge amount of infrastructure related information has been accumulated in each governmental/public organization. In order to highly utilize the information in various ways, it is necessary to know data specification in detail. However, it is not always easy because data specification is not necessarily standardized and varies time by time and by organization. In this regard, we JACIC created a Web site named 'JACIC/LCDM registry' in 2008 to register and retrieve data specification so that those who intends to develop new specification can refer existing specification easily, and who intends to develop application software to use such information can grasp data specification in detail. The paper introduces basic idea of JACIC/LCDM registry and present status as well as future prospects.
