# Personal Knowledge Development Personal Knowledge Development (PKD) is the deliberate practice of turning private notes, observations, sources, drafts, and relationships into an evolving personal knowledge system. It includes capture, naming, linking, synthesis, provenance, retrieval, and publication—not merely note collection. Bryant's long-running work connects PKD to executable documents, content derivation, semantic annotation, and feedback. A note can remain personal knowledge, become a source for public writing, generate addressable concepts, and later supply structured context to an AI system.
