=================

The basic ideas behind InfraNodus are:

• Graph DB model that can suit any purpose.
• Works on desktop and mobile.
• Make it easy to add nodes into a graph through a simple web interface.
• Work with what people already know and use well: #hashtags and @mentions, not nodes and edges.
• Use natural language to enter nodes in a graph (English and Russian morphology is supported)
• Move away from binary edges (e.g. A < - > B) to hyperedges in one statement (e.g. A and B and C or D)
• API and JSON export of all data;
• Twitter, Evernote, Gmail (Notes) import (TODO: gexf, xml, csv upload)
• Make it as lightweight, portable, and standalone as possible;
• Make it as fast as possible;
• Enable people to use ше collaboratively, both locally and over the internet (TODO);
• Your suggestions? (open an issue)

=================

InfraNodus is built on

• Sigma.Js for graph visualization;
• Neo4J for graph database storage (TODO: add support for OrientDB and Titanium);
• Node.Js
• Express Node.Js library;
• Node-Neo4J layer;
• Textexture algorithm for text network visualization;
• Help from the people on StackOverflow and Neo4J community;

=================

###Installation Guide To use this software you should install Neo4J 2.0 on your local computer. To install Neo4J on a Mac use homebrew (see Neo4J instructions here). For settings, check out How to Set Up Neo4J for InfraNodus. You may also find other wiki pages interesting.

You will also need to have npm Node.Js package manager on your computer and run npm install in node_modules folder of the project to install all the dependencies.

You might need to manually install ejs rending Node.Js module npm install ejs

You might also need to manually npm build node-lemmer

Check out the config.json.sample file and edit it to add your own Evernote and Twitter API credentials. Then rename it to config.json.

###Data Model

The general rationale for the data model used in InfraNodus is outlined in

• Cognitive Network Protocol article (more specific)
• From Cognitive Interfaces to Transcendental Protocols article (more general)
• Graph Database Model Draft detailed description

The main properties of this model are

• There are 5 labels (types) for nodes: Concepts, Statements, Contexts, Users, and Narratives
• Every expression of a user into the system is a Statement
• Example: "#antibiotics can fight #bacteria which are #dangerous for #health" is the user's input. The system creates 4 :Concept nodes from the hashtags inside the :Statement, which is linked to the :Context (by default, "@private") and all those are attached to the :User.
• Types of connections: :TO (between Concepts), :AT (Concepts to Context), :OF (Concepts to Statement), :IN (Statement to Context), :BY (to User)
• Narrative is implemented through creating a :Narrative node, which is linked to from Statements and Concepts by :INTO type of connection (think of :Narrative as another :Context)
• Narrative elements are linked to each other via :THRU type of connection.

This data model enables to create custom views for any kind of data and introduce the idea of narrative into holistic graph views.

This data model is derived from the Cognitive Graph DB Model draft created by Nodus Labs.

The current data model description utilized in InfraNodus app is available in https://github.com/noduslabs/graphdbmodel repository.

###Mobile Interface

InfraNodus can also be used on a mobile.
