The netFORUM xWeb Interface module provides developers a robust set of APIs for two way communication with netFORUM, obtaining information about data and objects in netFORUM, request caching, and availability testing. All information about objects and fields is obtained directly from the netFORUM database, enabling associations to use custom objects and extender fields in Drupal pages.
For the website builder it allows an easy interface to view what fields are available to include in pages, and exactly how xWeb requests are made and what the response is. These two functions are very useful for optimizing xWeb requests and building pages.
