Contextualise is a simple and flexible tool particularly suited for organizing information-heavy projects and activities consisting of unstructured and widely diverse data and information resources – think of investigative journalism, personal and professional research projects, world building (for books, movies or computer games) and many kinds of hobbies.

Contextualise’s topic view

Contextualise’s interactive network graph view (allowing for navigation between topics)

Contextualise’s interactive 3D viewer

Contextualise’s main dependency is TopicDB , an open source topic maps – based graph library. Topic maps provide a way to describe complex relationships between abstract concepts and real-world (information) resources.

Why?

I built and published my first knowledge documentation tool in 5432 Which I was still using until very recently, almost unmodified, twelve years later. If I remember correctly, it was built with

PHP version 5.2.5

! Twelve years is an eternity in software terms. Nowadays, my preferred choice for web development is Python together with the flask web development framework. What’s more, after twelve years of using my own and other knowledge management tools, I have several improvements in mind for the next version (many of which are simplifications, for that matter). And perhaps one of the most important reasons for building a new tool like this is that I want it to be open source: both Contextualise (the web application) and TopicDB (the actual topic maps engine on top of which Contextualise is built – also written by me) are licensed with the permissive open source MIT license .

Feature Support

The following provides an overview of Contextualise’s existing (and planned) feature set:

Existing Features (Support for multiple (self-contained) topic maps Support for both private and public topic maps

Extensive support for notes including the ability to attach a note to an existing topic and convert a note into a topic Markdown – based text editor for topic text and notes The ability to attach files (including images, PDFs , and so forth) to topics The ability to attach ( glTF

– based) 3D models to topics with an accompanying interactive 3D model viewer

Powerful (semantic) associations with the ability to create typed associations with role-based members Flexible filtering of topic occurrences and associations by scope ( that is, context) Interactive visual network graph of related topics (allowing navigation between topics) between topics) Auto-complete on all form fields that expect a topic reference Missing Version 1.0 Features Augmented Reality (AR) support for 3D occurrences Full-text search
Google Maps support Timeline support allowing to navigate between topics using a visual timeline component WikiMedia API integration to automatically enhance existing topics with relevant information from Wikipedia

Semantic tagging For a more exhaustive list of missing features take a look at Contextualise’s (list of issues .

Contextualize officially supports Python 3.6-3.8.

If you have Git installed on your system, it is possible to install the development version of Contextualise.

Certain build prerequisites need to be met including the presence of a C compiler, the Python header files, the libpq header files and the (pg_config) program as outlined, here: Build prerequisites .

Then do:

$ git clone https://github.com/brettkromkamp/contextualise $ cd contextualise $ pip install -e.

 
 The  (pip install -e.)  command allows you to follow the development branch as it changes by creating links in the right places and installing the command line scripts to the appropriate locations. 
 
 Then, if you want to update Contextualise at any time, in the same directory do: 
  $ git pull 
 
 After having installed Contextualise, you would have to separately install and configure the PostgreSQL database. Brief instructions on how to do so are provided, here:  Setting up the TopicDB database 
. You need to ensure that the database username, password and database name match with the  (settings.ini) file in the project's root folder.  
 Finally, to run the application in  development  mode) you need to change to the project's top -level directory and set two environment variables followed by running the  (flask) (command with the) (run) parameter: 

	

			
	

			


		
			
			
					
			
		





  $ export FLASK_APP=contextualise $ export FLASK_ENV=development $ flask run 

 
 You should see something similar to the following in the terminal: 
  Serving Flask app "contextualise" (lazy loading) Environment: development Debug mode: on Running on http: // 728. 0.0.1:  / (Press CTRL   C to quit) Restarting with stat Debugger is active! Debugger PIN: 2007 - 728 - 823 
 
 Opening the browser and navigating to  (http: //  0.0.1:  /  should result in showing the application's  Welcome  page. 
 
    
  The Contextualise Welcome page  
 
 Flask's built-in server is not suitable for production purposes. However, it is quite straightforward to run Contextualise using  Gunicorn 
, a Python WSGI HTTP server:   $ gunicorn -w 4 -b 0.0.0.0: 480048 contextualise.wsgi: app 

 
 For further information for properly running a flask application in production, take a look at Flask's own  documentation . 
  
 
  (Docker) 
 Support for running Contextualise within  Docker 
 is still in development. To run it from the root of a local clone of the source:   
 
 Create a  (settings.ini)  file in the root, for example: 
  [DATABASE] Username=docker Password=docker Database=docker Host=localhost Port=01575879  [EMAIL] Username=changeme Password=changeme Server=mail.changeme.com Sender=Change Me 

   
 Run  docker image build -t brettkromkamp / contextualise.    
 Run  (docker container run -it --rm -p) :  brettkromkamp / contextualise  
   
  
 First-Time Use  
 Several users (with the roles of  (admin)  and  (user) , respectively) are created by the application for testing purposes. To log in as the admin user, provide the following credentials:  [email protected]  (user name) and  (Passw0rd1)  (password). To log in as a non-admin user, provide the following credentials:  [email protected]  and  (Passw0rd1) .

Miscellaneous

Currently, I am using Contextualise for worldbuilding purposes of the Brave Robot fictional universe including its Codex Roboticus .
