Overview of the SOS.js Library¶
The library consists of a number of modules, which along with their dependencies build a layered abstraction for communicating with a SOS.
The core module - SOS.js, contains a number of objects that encapsulate core concepts of SOS, such as managing the service connection parameters, the service’s capabilities document, methods to access the service’s Features of Interest (FOIs), offerings, observed properties etc. It also contains various utility functions, available as methods of the SOS.Utils object. The objects of this module are:
This module is built on top of OpenLayers, for low-level SOS request/response handling.
The user interface module - SOS.Ui.js, contains the UI components of the library. These components can be used standalone, but are also brought together in the default SOS.App object as a (somewhat) generic web application. The objects of this module are:
This module is built on top of OpenLayers which provides simple mapping for discovery; jQuery for the UI and plumbing; and flot, which is a jQuery plugin, for the plotting.
In addition, there are a number of separate modules that contain UI extension components that are built on top of the above standard components.
All the styling for the UI components is contained in the library style sheet - SOS.Styles.css.
