IMPORTANT :

 As of version 5, the internals of Brain Annex have been completely overhauled to a Python/Neo4j implementation.  Details

This section of the website is for the obsolete v. 4

The "classic" (long-obsoleted) version 4 , which came out in 2015, was specifically web app for Knowledge and Media Management.

By contrast, the new version 5 , first released in late 2021, is a much more general full-stack based on a graph database.

=> FOR THE DOCUMENTATION OF THE CURRENT NEW VERSION (v. 5) of Brain Annex, go here.

A COMPLETELY-OVERHAULED Brain Annex

Version 5.0 (currently in "Release Candidate" stage) is a radical, total change of Brain Annex' internals!  The user interface of the included web app has remain relatively similar to version 4, but major new features have been introduced. 

NOTE : the web app included in the distribution is now JUST ONE USE CASE of a much more general technology stack usable for a wide variety of purposes!

Historically, Brain Annex started around 2015 as a multimedia content management system, but as of 2026 it has grown to be a general platform for full-stack management of graph databases.

GUIDE

KEY TECHNOLOGY ELEMENTS - General Python libraries to utilize Graph Databases

1. "GraphAccess" [formerly called "NeoAccess"], a library to interface with the Neo4j database, based on the earlier neo4j-liaison 
    
2. "GraphSchema" [formerly called "NeoSchema"], a library to implement a Schema Layer on top of the Neo4j database  (the Schema Layer, in conjunction with support from the core module, takes over a substantial part of the functionality that previously was the responsability of individual plugins.)
    
3. Specialized libraries for "Categories", "Collections", "Full-Text Indexing", and visualization

KEY TECHNOLOGY ELEMENTS - Web API and Web App

1. Flask for the web API
    
2. Vue.js for the front-end UI
    
3. The Cytoscape.js library for interactive custom visualization in "balls and lines" mode
