 The [TAP Attribute Dictionary](tap-core-person-schema.adoc) defines a large collection of 
-attributes used across various components of the TAP portfolio and higher education more generally. The

-best thought of as an *attribute library* that can be drawn from to construct other documents, specifications, and software artifacts.

+TAP uses the word "schema" as a rather broad and loose term for data models generally. However, beyond that, TAP provides careful definitions of two specific schema-related terms, "format" and "protocol".
 
 * **Formatting**: Mappings of the TAP Attribute Dictionary entries to a specific markup form, such as
   JSON, XML, LDAP, or YAML.
