# Personal Knowledge Graph A personal knowledge graph represents a person's people, accounts, devices, places, events, organizations, claims, and source artifacts as typed entities connected by explicit relationships and provenance. ## Notebook precursor [[Scanned_20260730-1913]] performs this work manually. Contact slips, residence dates, device tasks, account lineages, receipts, routes, company lists, diagrams, and conceptual maps become cross-referencable nodes. The notebook's weakness is not absence of graph thinking but the absence of machine-readable edge types, confidence, source identifiers, dates, and privacy classes. ## Required archival fields - canonical entity and aliases; - exact source notebook and page; - visible evidence versus correction or later interpretation; - relationship type and direction; - date or date range; - confidence and unresolved alternatives; - sensitivity class, with secrets stored outside the public graph. ## Relationships [[Control-Plane Continuity]] · [[Identity and Account Continuity]] · [[Documentary Evidence Continuity]] · [[Personal Digital Twin]] · [[Index - Pattern Ledger]] ## Source - [[Scanned_20260730-1913]], notebook-level synthesis. ## Scanned_20260730-1845 overlay PDF page 27 of [[Scanned_20260730-1845]] explicitly asks for a visual graph of every company and its historical data. The notebook supplies a broader schema than the earlier paper continuity ledger: companies and acquisitions, domains and accounts, certificate issuers, official credentials, devices, permissions, travel/insurance records, legal repositories, and semantic goals. The decisive addition is time-aware [[Data Provenance]]. A name or platform must be linked to former names, owners, source records, dates, and confidence rather than treated as one timeless node.
