This page is an experimental DATR working environment. The default values permit a simple demonstration of some of the features of DATR.

DATR is a declarative representation language for modelling default inheritance of the values of attributes; it was developed by Evans and Gazdar at U Sussex, UK, in the late 1980s.

ILEX is an empirical model of language based on an integrated lexicon, in which the abstract compositional structure is distinguished from phonological and prosodic temporal structuring and from logical form. ILEX is also a formal model for applications of the DATR formalism in lexicology. See Lexical Syntax in ILEX/DATR and DATR theories or DATR programmes? .

The hypertext representation language HYPR is a different DATR application. HYPR permits abstraction from the details of hypertext structure to arbitrary levels of generality; it can also be seen as a high-level recursive macro language for low-level markup codes such as HTML. The HYPR source document for this page is accessible by the top right link.

The implementation of DATR used for the illustrations is "mud", a simple UNIX implementation with few special features. The implementation used for compiling HYPR into HTML is "node", a more advanced implementation in SICStus Prolog under UNIX.
