nap — Narrative Addressing Protocol

NAP is a protocol that makes narrative resources addressable, resolvable, and interoperable across tools, storage systems, formats, and AI workflows.

Characters, locations, scenes, props, and entire fictional repositories — NAP gives each one a stable URI, a human-and-machine-readable manifest, a content-addressed history, and a resolver that connects them all.

In the same way that IPFS content-addressed files and OCI container-addressed images, NAP is narrative-addressed — a universal namespace for the building blocks of stories.


Why NAP?

Today, narrative assets live in silos:

  • Worldbuilding docs in Notion or Google Docs
  • Character sheets in spreadsheets
  • Concept art in Dropbox or S3
  • Scene breakdowns in Final Draft or Fade In
  • AI prompts scattered across chat logs
  • 3D assets on Sketchfab or Polycam

None of these tools talk to each other. NAP unifies them under a single addressing and resolution layer.

nap://starwars/character/lukeskywalker
nap://starwars/location/tatooine
nap://starwars/scene/cantina
nap://toystory/prop/andy-hat

Core Primitives

NAP is built on four primitives:

1. URI — Identity

A nap:// URI identifies any narrative resource. Version, branch, and tag are orthogonal selectors passed alongside the URI — never encoded in the path (mirrors Git, OCI, and package managers).

nap://starwars/character/lukeskywalker#references.appears_in
────┬── ───┬──── ────┬──── ──────┬────── ─────────────┬───────────
 scheme repository  entity_type entity_id          fragment (query)

2. Manifest — Current State

A YAML manifest is the durable representation of a narrative resource. It is simultaneously:

  • Human-editable — readable by worldbuilders
  • Machine-editable — structured, schema-validated
  • Agent-readable — subtree-queryable for AI workflows
  • Portable — no runtime dependency, just a file
  • Signable — hash the content, sign the hash (Ed25519 in v0+)
  • Versionable — the manifest is what gets committed
id: "nap://starwars/character/lukeskywalker"
name: "Luke Skywalker"
entity_type: character
version: 17
properties:
  homeworld: "nap://starwars/location/tatooine"
  species: human
representations:
  reference_image:
    hash: "sha256:e3b0c44..."
    format: png
provenance:
  model: "midjourney-v6"
  prompt_hash: "sha256:abc123..."
head: "a72c9f3b..."

3. Commit — History

Commits are content-addressed (SHA-256) snapshots with patch metadata. The manifest stores only head — a pointer to the latest commit. Full history lives in the VCS, keeping manifests bounded.

4. Resolver — URI → Manifest

The resolver turns a nap:// URI into a manifest (or a subtree of one). With optional selectors for branch, tag, or commit hash, it supports versioned resolution and fragment-based queries for efficient data access.


Entity Types

Type Example URI Description
character nap://starwars/character/lukeskywalker Persistent character with identity across scenes/episodes
location nap://starwars/location/tatooine Spatial location within a fictional repository
scene nap://starwars/scene/cantina Narrative scene — participants, timeline, events
prop nap://toystory/prop/andy-hat Physical object with materials, variants, ownership
group nap://toystory/group/buzz-and-woody-flying Mixed-media groups
world nap://starwars/world/starwars The repository itself — rules, canon, top-level metadata

Repository Layout

Each repository is a Git repository on disk:

starwars/                    ← repository root (Git repo)
├── .nap/
│   └── config.yaml          ← repository configuration
├── repository.yaml            ← world manifest
├── characters/
│   ├── lukeskywalker.yaml
│   └── darthvader.yaml
├── locations/
│   └── tatooine.yaml
├── scenes/
│   └── cantina.yaml
└── props/

Design Principles

  1. Content-addressed — Every piece of content is identified by its cryptographic hash. Manifests are immutable once committed.

  2. URI-addressed — Every entity has a stable, portable URI. URIs are never invalidated by renames or moves.

  3. Human-readable — YAML manifests are readable by worldbuilders and AI agents alike.

  4. Portable — No runtime dependencies. A manifest is just a YAML file. A repository is just a Git repo.

  5. AI-native — Subtree queries let AI agents fetch exactly the data they need. Provenance tracking records generation metadata.

  6. Schema-validated — All manifests conform to a JSON Schema. Invalid manifests are rejected at commit time.

  7. Decentralized — Repositories are Git repositories. They can be cloned, forked, merged, and published independently.

  8. Extensible — New entity types, representation formats, and merge strategies can be added without breaking existing data.
