The document proposes a vision for a future of education centered around Dynamic Knowledge Gardens, which are global learning support infrastructures that use collaborative and social opportunities on the web. They would allow for lifelong, just-in-time learning through topic maps and collaborative tools that help weave information into a shared understanding and allow learners to harvest knowledge from each other. Examples are presented of early prototypes that demonstrate dynamic mapping of topics, social bookmarking, collaborative discourse, and annotation of relationships between ideas.
