Hi all, as you probably know GeoTools is now sometimes carrying around JSON in feature attributes (e.g., see JSON support in PostGIS data store). The JSON is represented as a String.
Now, I'd like to add a filter function to parse and extract specific properties out of the JSON string... which requires new dependencies. And boy we have a mess of them in the classpath already: - json-simple, used in geojson and mbstyles, but dead, last release is 2012 - json-lib, used in GeoServer for geojson generation, and also dead, last release is 2010 - jackson, used by Spring and directly by some GeoServer community modules, with recent releases and latest commits of only a few days ago There are basically two languages to extract stuff from JSON, json-path and json-pointer. json-path is the one I would have preferred as it's more powerful, but its situation library wise is not exactly in great shape, the jayway implementation uses yet another json java library, json-smart2, also dead. There are a couple of other options for json-path, either dead or with a bizzarre "do not evil" licence. json-pointer is instead supported directly by jackson-core, which is well alive, and comes with a 300kb jar that has no external dependencies. This seems the best bet, just one hesitation... should I add a jackson-core to gt-main? On one side, it seems a large-ish dependency for just a function, on the other side having a single class new module also seems a bit overkill. Opinions?
