I need to download some data that's only available through a Map Service on a public ArcGIS server. I was thinking of downloading the data 1000 features at a time using JSON, but in order to do that I need to get the list of ObjectIds. The list of ObjectIds gets returned in a query request and the response looks similar to this:
{ "objectIdFieldName": "OBJECTID", "objectIds": [ 1, 2, 3 ] }
I could parse this using Python, but I would like to be able to do it in FME 2014. When I use the JSON reader, each objectId gets read as a separate attribute and FME ends up hanging because it's trying to read tens of thousands of attributes! Is there a parameter setting or a better reader or transformer that would help?
