RFC 2244:

ACAP is designed to support remote storage and access of program option, configuration and preference information. The data store model is designed to allow a client relatively simple access to interesting data, to allow new information to be easily added without server re-configuration, and to promote the use of both standardized data and custom or proprietary data. Key features include "inheritance" which can be used to manage default values for configuration settings and access control lists which allow interesting personal information to be shared and group information to be restricted.

Context.
(RFC 2244) An ordered subset of entries in a dataset, created by a SEARCH command with a MAKECONTEXT modifier.

Dataset.
(RFC 2244) One level of hierarchy in ACAP's tree of entries.

Dataset class specification.
(RFC 2244) The rules which allow a client to interpret the data within a portion of ACAP's tree of entries.

Entry.
(RFC 2244) A set of attributes with a unique entry name.

Metadata.
