+# Architecture
+The whole application comprises of a number of modules on the client side
+* __gui2-fw-lib__ This is a collection of client side component, services and base
+classes that are reused among all modules [more details..](../gui2-fw-lib/README.md)
+* __gui2-topo-lib__ This is the Topology view only [more details..](../gui2-topo-lib/README.md)
+* __fm_gui_lib__ This is the Fault Management table [more details..](../../apps/faultmanagement/fm-gui2-lib/README.md)
+* __gui2__ This is the front end entry point application and brings together all
+other libraries. It also holds all of the tabular applications such as Applications
+view and Devices view, and manages the routing between the different views. 
+
+All of these modules talk to the backend server mainly through a WebSocket connection
+passing JSON snippets asynchronously in both directions.
+In some places the client side code loads data through a plain HTTP GET call, and
+these are served by servlets on the backend. Similarly raster graphics are loaded
+through a servlet.
+
+Much of the graphics in the application are made from SVG paths and primitive objects,
+and are displayed smoothly by HTML5 compatible browsers. Occasionally the d3
+libraries (such as d3-force) are used to help position graphics, but an over
+dependence on d3 is mainly avoided.
+
+The main framework used is Angular 7, with a strong emphasis on making resuable
+components, directives, services and classes. Angular Routing and animation are
+also used.

 # Development
 There are 2 ways to go about development - 
-1. rebuild the code and rerun through Bazel (much like can be done with any ordinary ONOS app) 
- (this is not optimal though since in this mode the browser side code is built in '--prod' mode
- and all debug symbols are stripped and debug statements are not logged and the code is uglified and minimized.
- It is useful for testing "prod" mode works though and saves having to set up direct development) OR
-2. use Angular 7 CLI (__ng__ command) to rebuild on the fly (must faster for development)

 For 2) it's well worth becoming familiar with Angular CLI.
-The project is created with [Angular CLI](https://github.com/angular/angular-cli) v7 to simplify development of the browser side code.
-It is complicated to set up, but is worth the effort if you have more than a day's worth of development to do.
-This allows you to develop the Angular 7 TypeScript code independent of ONOS in a separate container. 
-Since WebSockets have been implemented - there is a requirement to run ONOS in the background.

-There is no need to install node, npm or ng again on your system, and indeed if they are already installed, it's best
-to use the versions of these that's used by Bazel. To do this add the following 2 entries to the __start__ of your PATH environment variable.
