Knowledge Tree

Overview

Knowledge Tree Logo

Knowledge Tree is a link aggregating portal. It presents content structured according to the folder-document paradigm. Knowledge Tree provides authentication and authorization and implements a simplified form of access control. It supports collaborative authoring and social annotation. Knowledge Tree is primarily oriented towards ADAPT² architecture.

Writing Notes

Ability to write notes for different resources ob Knowledge Tree is a feature inspired by user feedback. The absolute majority of content on Knowledge Tree is educational, including a large body interactive exercises. Note-taking is one of the primary learning techniques in the paper-and-pencil world that we decided to build into Knowledge Tree.

How It Works

A note can be written for any 'node' (folder, document, linked resource) on Knowledge Tree. To create a note, user has to first open the desired folder, document, or resource in Knowledge Tree and in the top menu click on the 'bubble' icon ([Image:KnowledgeTree.notes.menu_icon.png|20px]).

Standardization

Knowledge Tree structure is partially serialized as RDF. For more information refer to Knowledge Tree RDF Binding.
