To add some more background for grammar-based bioinformatics parsers, take a look at SRS (Sequence Retrieval System) from the early 1990s, by Etzold and Argos.

It was the last generation of purpose-built database systems, before off-the-shelf object-relational systems took over, and used a set of grammars in a declarative language to parse and index flat files.
