Getting RESTful

What is OpenLayers?
• JavaScript Library
• No server-side dependencies
• Free Software, developed for and by the Open Source
software community

Why not use ESRI JSAPI?

Understanding OpenLayers
“OpenLayers is not designed to be usable 'out of the box'. It is a
library designed to help you build applications, so it's your job as an
OpenLayers user to build the box.”
-Christopher Schmidt on OpenLayers Users List

OpenLayers Basics

ArcGIS Server and OpenLayers
• At version 2.8, ArcGIS REST API support exists
in OpenLayers
– ArcGIS Dynamic Maps
– ArcGIS Tiled Maps
– Query
• Other functionality is outside the trunk
– Look for Sandbox tools that you can patch
OpenLayers with.
