The AGFL Grammar Work Lab
The formalism for the to attribute grammars related Affix Grammar over Finite Lattices developed at the University of Nijmegen is being applied to natural-language processing. Context-free grammars can be described on a primary context-free level augmented by secondary-level features for expressing agreement between parts of speech.

Micro Attribute Grammar System
The UU_AG system is a very simple program that reads a set of files containing an attribute grammar, in which semantic functions are described through Haskell expressions.
