The following table lists the top-level hierarchies for which there are defining attributes. Not all hierarchies in SNOMEDCT have defining attributes. They were developed in the priority areas first. The highest priority was to develop defining attributes that would be useful for aggregated analysis of outcomes, decision support, knowledge-based practice guidelines, etc. in a clinical setting. Therefore, defining attributes in SNOMEDCT were first assigned to those hierarchies where retrieval of clinical data is most useful and relevant: procedure, finding, and situation with explicit context. Concepts in other hierarchies can be primitives and still serve as the values of attributes for the concept definitions of the main hierarchies.

Some domains are not top-level hierarchies, and some top-level hierarchies are not domains. Each item in the Hierarchy column refers to the top-level hierarchy where the attribute applies. Some of these do not actually apply at the very top of the hierarchy, but are restricted to a domain defined lower down. Some of them apply to more than one top-level hierarchy. Each item in the Attribute column refers to a single attribute that resides in the Attributehierarchy.

Each attribute has a specific domain to which it applies; in many cases these domains are simply the same as the top-level hierarchies, as listed in parentheses after the domain name. In other cases, there is a more restrictive domain. In the following table, the left-hand column names the specific domain, and the right hand column the defining attributes.
