This page sketches some of the principles which will be used in the development of the framework. Once final decisions are taken, these ideas will be merged into the Project Architecture, tools, and design standards document page

1) Working Graph (WG) and Layer Graphs (LGs)

LG nodes and layers reference to WG and have topological and spatial information

2) Layer Graphs

LG are updated into the server

3) Graphs sessions management

WG and LG can be serialized to Mongo DB on logout or on demand

4) Layers definition procedures

  • select and unselect
  • filter on attributes

5) Layers management

A front end and a user interface are necessary to allow layers creation
