What Does a<Transmittal Root> Organize?
A <Transmittal Root> organizes
- <Environment Root> instances that represent some environment
- <Library> instances that serve as repositories of representations of environmental objects that tend to be shared and reused
- metadata that applies to the entire transmittal
-
Any given <Transmittal Root> is required to supply some basic metadata, but otherwise data providers are free to use only those <Environment Root> and / or <Library> organizations that express their particular environmental data sets.
