These five main pillars supporting the establishment of IDSN inseparable pillars
with the other pillars, therefore the five pillars are interrelated. Each pillar requires the support of the other pillars. One of the pillars
IDSN supporters called Main Data is a pillar of
establish and coordinate the construction of primary data (fundamental data sets)
with emphasis on the activities include:
a. Standard-setting main data products and data bases
b. Standard-setting procedures and data acquisition network
c. Preparation of standard protocols and data distribution system of the main access
The most fundamental pillars to be built in the main data is to manage the data in order
can be easily accessed and distributed in accordance with the specific purpose
and the public by anyone in need. System to be built
is referring to the system known as the Clearinghouse system.
