Everything is a URL Hierarchy of resources–Catalog, Services (Map, Geocode, etc.), Layers, Tasks, etc.

wget, curl... JavaScript, Ruby, Python, Perl... Java, .NET–interoperable

Resources and Operations Everything is a resource...– But…

We have categorized resources into 2 types–Resources that are in and by themselves

Catalog, Map Service, Layer, etc.–Resources that are results of operations

Users are used to the vocabulary:– Export Map v. Map Image– Query v. Results– Reverse Geocode v. Location AddressESRI Developer Summit 2008 16
