System Of Registries
The System of Registries (SoR) is a resource for environmental system developers and enterprise
architects.
It also provides environmental program managers and users of environmental information with automated
services to enable better understanding of environmental terminology and data used by the Agency.
Data standards are an integral part of these services. Information about data standards may be accessed on the separate Data Standards Web Site.
