notedocument

Notedocument is a hypothetical or general term for a structured, interoperable format for capturing and organizing notes. It is designed to support knowledge management workflows by combining rich text with metadata, links, and version history.

The format and data model: Notedoc files (extension .ndoc) store a document as a tree of notes or pages. Each note includes an identifier, title, body content in rich text or lightweight markup, timestamps for creation and modification, a set of tags or categories, and a list of backlinks to related notes. The model supports attachments and cross-linking between notes, enabling networks of ideas.

Metadata and semantics: Notedocument defines optional metadata fields such as author, source, citation, licenses, and provenance. It supports semantic tagging through integrated metadata schemes (for example JSON-LD or RDF-based annotations) to improve searchability and interoperability with other systems.

Features and capabilities: Notedocument emphasizes hierarchical notebooks, backlink networks, tagging, and version control. It provides import and export to common formats (PDF, HTML, Markdown) and is designed for offline use with synchronized repositories. Applications include personal knowledge management, academic note-taking, and collaborative documentation.

Status and adoption: As a concept, notedocument serves as a reference model rather than a single product. It is advocated by communities focused on structured note-taking and knowledge graphs, while real-world adoption is fragmented across vendors, each with own formats. It aims to complement existing standards and tools.
