brainannex-neo4jv4 5.0rc6

Full-Stack Data/Knowledge Management with Neo4j version 4

Brain Annex - a full technology stack on top of GRAPH DATABASES

This is a mono-repository of:

1. The "Brain Annex" python library
2. The "Brain Annex" web app (backend and frontend)

Graph databases currently supported:

1. Neo4j, version 4.4 (the final release of major version 4)
2. Neo4j, version 5.26 (the final release of major version 5)
3. We expect to later support others, possibly Memgraph and AWS Neptune

Do you only care about the python library?

Simply:

• pip install brainannex-neo4jv4
  or
• pip install brainannex-neo4jv5
  (based on which major version of Neo4j you use.)
  Nothing else to do!

Then use it with imports such as:
from brainannex import GraphAccess
(notice that we are just saying brainannex here, NOT the full install name!)

IMPORTANT for installing the web app - to switch between supported databases:

1. Must change the database driver, in the first line of requirements.txt
2. Must comment/uncomment the appropriate version lines in the brainannex/__init__.py file, for the InterGraph module, which is database-specific.

Brain Annex's Technology Stack (Overview)

BRAIN ANNEX PYTON LIBRARY

From lower to higher levels:

• InterGraph library (low-level, database-specific layer)

• GraphAccess library (python interface offering many services)

• GraphSchema library (optional Schema layer)

• plus several other specialized high-level libraries

---

What is a "Schema layer"?

A schema layer harmoniously brings together the best of the flexibility ("anything goes!") of graph databases, and the "law and order" aspect of relational databases!

BRAIN ANNEX WEB APP

• Python/Flask (for web API, and web app pages)

• Vue2.js

EXAMPLE of use case : Multimedia Knowledge Representation and Management

Motivation and overview

What are Neo4j/Graph Databases, and why do they matter?

If you're new, here's a gentle brief intro.

Brain Annex's Technology Stack (Details)

Brain Annex may be used as a standalone web app, or used to power other web apps.
The libraries that are the bottom layers may also be used independently.

How to set up and use Brain Annex WEB APP

(Note: if you only care about the python library, just pip install it! This section doesn't apply to you!)

The underlying graph database and the Brain Annex web app may be installed either locally or on a remote server.

The database and web app may reside on the same or different machines.

SETUP

INSTRUCTIONS

EXAMPLES of Schemas available for import

(For instructions on how to import the Schemas, see the setup page, above)

EXAMPLE 1 - the available default Multimedia Content Management System

The ROOT node for the Categories is shown in blue at the top.

---

EXAMPLE 2 - same as example 1, but with sample extra Classes (representative of user-added schema)

The diagram below is split in 2 parts, for readability.

"chem" is an example of a custom Class.

The following second half of the diagram shows the remainder of the Schema, detailing Classes that are instances of the "Records" Class. Most of the items in this diagram are examples of typical user-added schema:

Major components

• GraphAccess : a library to connect to Neo4j with python. It provides many services. Link

• GraphSchema : a higher-level schema-based library on top of GraphAccess. Link
  Article explaining this layer

• CK Editor : open-source JavaScript library to implement an online HTML Editor.
  Website. (Note: Brain Annex uses version 4 of the CK Editor)

• API : the endpoints appear in this file

• Web pages : the pages generated by Brain Annex are listed in this routing file

• Navigation bar : Brain Annex can be used either as a standalone web app, or integrated with another site.
  The navigation is implemented in this package
