Hi:

I was curious to know if any work had been attempted earlier to provide a
native CQL parser in JavaScript?

With the new support for OpenSearch media types in SRU 2.0 (see OASIS SWS
docs [1]) the central role of the browser in both generating CQL queries and
consuming SRU responses becomes ever more prominent.

(A case study in fielding a variety of media types is nature.com OpenSearch
[2] which inter alia supports JSON. A gallery of demo apps using this media
type is available here [3] and gives some idea of what can be done.)

In previous researches I have turned up JS/CC [4], a LALR(1) parser and
lexical analyzer generator for JavaScript, written in JavaScript. I don't
know if this could be useful in helping develop a native CQL parser for
JavaScript. I would investigate further but for time and skills resources
which are both wanting.

It would be truly wonderful if somebody could undertake such a work and put
CQL comprehension directly into the client.

Cheers,

Tony
