California, USA, 12 April 2007: ESRI announced the latest version of the ArcWeb Services REST application programming interface (API). This API is hosted by ESRI and offers developers an easy alternative to using SOAP-style Web services for building mapcentric, decision-making applications.
The ArcWeb Services REST API offers a number of benefits for Web developers including ease of use, faster deployments, and interoperability. Developers who understand HTTP and XML can start building mapping applications immediately using their existing Internet application development toolkits. The REST API is inherently lightweight, using simple HTTP URL requests, so that any client application with HTTP support can easily make API requests to ArcWeb Services without the need for a SOAP WSDL.
Using the ArcWeb Services REST API, client applications only need to know about sending and parsing plain text URLs. This means that applications can be built faster because the mapping application logic is simplified. Knowledge of XML specifications is not required, and SOAP toolkits aren’t needed to build functionality for forming XML requests and parsing results.
The latest features in the ArcWeb Services REST API include:
Control for multiple layers of map data
Access to tiled map data sources
Ability to automatically manage map projections
