Folks,

I think this datastore is now stable enough for people to have a go at it. 
(Please 
use the v0.2.2 release from https://github.com/lmoran/arcgis-rest.)

The ArcGIS ReST API is huge, and we were interested only in getting data with 
bounding box queries, hence the datastore is very limited in scope. More 
specifically, only the FeatureServer services on either ArcGIS Online (Open 
Data) 
or ArcGIS Server FeatureServers are covered so far.

In addition, there are a few issues:
1) The API returns "enriched" GeoJSON, hence JSON fragments that do not conform 
to 
GeoJSON are discarded. (The datastore own GeoJSON streaming parser is based on 
Gson).
2) The query filter is ignored, only the request bbox is used to query the API.
3) Since a different call for every dataset in an API endpoint (either OpenData 
or 
FeatureServer) has to be performed, endpoints with many datasets can take a 
long 
time to load. (By the way ESRI seem to be throttling back frequent requests 
-presumably to fend off DDOS attacks.)

Please, have a go and tell us how to improve it.

Cheers,
