- ...signs:
- A number of variants of the template outlined here have been known
since the early nineties as the ILEX
(Inheritance LEXicon or Integrated LEXicon) model;
lexica based on the model have generally been formulated as DATR theories.
Many published and unpublished ILEX/DATR `microlexica' have been implemented
on the basis of this model.

- ...values.
- Representative studies using DATR models have been carried out by
Gibbon on Arabic paradigms and Kikuyu tone ([Gibbon 1990]),
Reinhard & Gibbon on Arabic and Kikuyu ([Reinhard & Gibbon 1991]),
Gibbon on German compounds ([Gibbon 1992]),
Cahill on morphophonology in the lexicon ([Cahill 1993]),
Bleiching on German morphology and lexical prosody
([Bleiching1992], [Bleiching 1994]),
Corbett & Fraser on Russian inflection ([Corbett & Fraser 1995]),
Bleiching, Drexel & Gibbon on German inflection ([Bleiching, Drexel & Gibbon 1996]),
Gibbon, Tseng & Folikpo on Ewegbe tone ([Gibbon, Tseng & Folikpo 1997]).

- In some sources, the symbol is reversed by analogy with the subset
relation over the extensions of the feature structures.

- ...atoms
- DATR nodes are character strings starting with an upper case
character, or declared character strings;
DATR atoms are either character strings starting
with a lower case character, or character strings enclosed in single right
quotes, or declared character strings.

- ...example
- The derivation was produced with the ZDATR interpreter, [Schillo 1996]. The numbers indicate depth of local inheritance, path inheritance, and position in the right-hand-side sequence; the `52#52' sequence separates the matched prefix of the local environment from the remaining suffix, and the RULE number refers to the DATR inference rule which applies to the current value expression under evaluation.
