National Release Centres
Each national member of IHTSDO has a National Release Center (NRC).
The purpose of a National Release Center is to provide a central (and single) point within the member's jurisdiction to:
- Interface to the IHTSDO
- Interface to other NRCs
- Interface to all entities within the member's territory who have an interest in the products or business of the IHTSDO
- Manage and control the use of the IHTSDO's assets within the member's territory
- Interface to the support organization in line with IHTSDO policies, procedures and regulations. Under normal circumstances there should be no direct contact between entities within a member's territory and the support organization
- Have the total responsibility for distribution and support of the Association's Terminology Products within the member's territory and the IHTSDO has no obligation to perform or provide any such distribution or support.
See contact details of the National Release Centres here or on each member's homepage.
