Up: The DATR language
Right: Local inheritance
DATR descriptions associate values with node/path pairs. This is
achieved in one of three ways: a value is explicitly stated, or it is
explicitly inherited, or it is implicitly specified (stated or
inherited) via the default mechanism. We have already seen how values
are explicitly stated; in this and the following subsections, we
continue our exposition by providing an informal account of the
semantics of specification via inheritance or by default. The present
is only concerned with explicit (i.e., non-default) inheritance.
Section 3.3 deals with implicit specification
via DATR's default mechanism.
