+# Building a Metadata Provider
+
+A metadata provider is a small web service that answers BookOrbit's metadata searches from a source
+it does not know: a regional catalogue, a fan wiki, a manga database, your own spreadsheet. BookOrbit
+calls it over HTTP and never runs its code, so you write it in any language, release it on your own
+schedule, and nobody has to change BookOrbit for it.
+
+This guide takes you from an empty folder to a published image that anyone can add to BookOrbit.
+To add a provider someone else made, see [External Metadata Providers](METADATA_PROVIDERS.md).
+
+## How it works
+
+```text
+BookOrbit                          your provider                    the source
+   | GET /search?query=Dune ------->  |                               |
+   |                                  | -- its own API or pages ----> |
+   |                                  | <---------------------------- |
+   | <---- { "matches": [ ... ] } --- |                               |
+```
+
+Your provider answers three requests:
+
+- `GET /provider/info`: who it is (name, a permanent key, version, icon, what it can do).
+- `GET /search`: books matching a title, author or ISBN, best first.
+- `GET /book/{id}`: one book by the id your provider gave it earlier. Optional, but recommended.
+
+BookOrbit caches answers, merges them with its other sources through field rules, stores your ids
+on the books it matches, and shows your icon and colour wherever your results appear.
+
+## Before you start
+
+- **Check the source's terms.** You are responsible for how your provider uses its source. Prefer an
+  official API over scraping pages: APIs change less often, and many sites forbid scraping.
+- **Choose the key now, and never change it.** The key (such as `mangabaka`) is how BookOrbit files
+  every id and rating your provider gives it. A provider that changes its key is a new provider to
+  BookOrbit, and users have to add it again.
+- **Choose a language you will keep maintaining.** There are starters in Rust and Go. Rust is what
+  the published providers use: the same provider ran in about a third of Go's memory. Go needs
+  nothing but `go run`. Python, Node or anything else that serves JSON works too.
+
+## Quick start
+
+The [bookorbit-metadata-providers](https://github.com/bookorbit/bookorbit-metadata-providers)
+repository has a working starter in Rust and one in Go, and a conformance checker. Both starters
+serve one made-up book and behave the same; pick the language you prefer.
+
+1. **Copy a starter.**
+
+   ```bash
+   git clone https://github.com/bookorbit/bookorbit-metadata-providers.git
+   ```
+
+   For Rust:
+
+   ```bash
+   cp -R bookorbit-metadata-providers/starters/rust my-provider
+   ```
+
+   Or for Go:
+
+   ```bash
+   cp -R bookorbit-metadata-providers/starters/go my-provider
+   ```
+
+2. **Run it**, so you can see every endpoint working before you change anything. In Rust,
+   `cargo run`; in Go, `go run .`. Then:
+
+   ```bash
+   curl "http://localhost:8080/search?query=earthsea"
+   ```
+
+3. **Name it.** Change `info()` in `src/main.rs` (Rust) or `main.go` (Go): give it your `name` and
+   the `key` you chose.
+
+4. **Connect your source.** In `src/source.rs` or `source.go`, replace the example with calls to
+   your source:
+   - Search returns matches best first, at most the query's limit.
+   - Lookup returns the book for an id, or nothing (`None`, `nil`) when the id does not exist.
+   - Return an error for anything else that goes wrong. Never hide a failure behind an empty list:
+     to BookOrbit, an empty list means "this book is not there", and it remembers that.
+
+5. **Check it against the contract.** With your provider running:
+
+   ```bash
+   cd bookorbit-metadata-providers/conformance && go run . -url http://localhost:8080 -query "Dune"
+   ```
+
+   It prints a line per check and ends with the number of failures and warnings. Fix every failure;
+   each warning says what BookOrbit will do instead.
+
+6. **Try it in BookOrbit.** Add it under **Settings > Metadata > Providers > External providers**
+   with **Allow private address** on, choose **Test**, turn it on and search for a book.
+
+## Recommendations
+
+**Identity**
+
+- Serve `/provider/info` with a `name`, a `key` and a `version`.
+- Bump `version` whenever your answers change shape: new fields, different mapping, a fixed bug.
+  BookOrbit keeps cached answers per version, so an unchanged version keeps serving old ones.
+- Give it an icon (`avatarUrl`) and a `color`, so your results are recognisable at a glance.
+
+**Answers**
+
+- Put the best match first, and return a handful rather than everything: BookOrbit uses at most 50,
+  and a person picks from the first few.
+- Leave out what is not a book on a shelf: reviews, articles, interviews, collections pages.
+- Support `GET /book/{id}` and declare `lookup: true` when your source has stable ids. Refreshing a
+  book by id is faster and more accurate than searching for it again.
+- Declare what you can fill with `supportedFields` and `mediaTypes`, so BookOrbit only asks you for
+  what you have.
+- Give each record its own `mediaType` when your source has more than one: a light novel is
+  `book`, its manga `comic`. When titles are otherwise alike, BookOrbit prefers the record that
+  matches the medium of the book being matched, so a novel's EPUB gets the novel.
+
+**Data**
+
+- Plain-text descriptions: strip HTML, Markdown and site markup, and keep paragraphs.
+- Write people's names the way the book does. Give years as four digits, ISBNs without hyphens,
+  ratings on a 0-5 scale.
+- Return the largest cover your source has, with `coverWidth` and `coverHeight` when you know them.
+- Fill only what you know. A missing field is better than a guessed one.
+
+**Failures and limits**
+
+- Answer `429` with `Retry-After` when your source throttles you. BookOrbit backs off.
+- Answer `502` or `503` when your source fails. BookOrbit may then answer from its cache.
+- Answer `"partial": true` when some matches could not be fetched, so the answer is not cached as
+  complete.
+- Pace your calls to the source inside the provider, whatever BookOrbit asks for: several BookOrbit
+  servers, or other apps, may share one provider. Declare a `rateLimit` too, so BookOrbit does not
+  queue more than you can serve.
+- Identify yourself to the source with a `User-Agent` such as `my-provider/1.2.0`.
+
+**Safety and privacy**
+
+- Keep it stateless and read-only. It needs no database and no volume.
+- Run as a non-root user in a minimal image (`scratch` or distroless). Both starters' Dockerfiles
+  already do both.
+- Support an `AUTH_TOKEN` (both starters do) for anyone who exposes it beyond their own network.
+- Log failures, not the titles people look up.
+- Say in your README which details you send to your source. BookOrbit sends you the title, author
+  and ISBN of each book it asks about.
+
+## Test it
+
+- **Unit tests with real answers.** Save a few real responses from your source into `testdata/`,
+  trimmed to the fields you read, and test your mapping against them. Tests then run offline and
+  keep passing when the source is down. Both published providers do this.
+- **The conformance checker** before every release: it checks the endpoints, types, limits, status
+  codes, icon and colour the way BookOrbit reads them.
+- **In BookOrbit:** **Test** in the provider's settings runs a real search and shows what came back.
+
+## Package it
+
+Ship it as a container image. Each starter's `Dockerfile` builds a static binary into an empty
+`scratch` image that runs as a non-root user: about 1 MB for the Rust starter, 5 MB for the Go one.

+docker build -t my-provider .
+```
+
+```bash
+docker run --rm -p 8080:8080 my-provider

+
+Build for both `linux/amd64` and `linux/arm64`: many people run BookOrbit on a Raspberry Pi or another
+ARM machine.
+
+```bash
+docker buildx build --platform linux/amd64,linux/arm64 -t ghcr.io/your-name/my-provider:0.1.0 --push .
+```
+
+## Publish it
+
+GitHub Container Registry (GHCR) is free for public images and sits next to your code.
+
+1. **Push your code to GitHub.**
+2. **Add a release workflow** as `.github/workflows/publish.yml`. Pushing a tag such as `v0.1.0` then
+   builds both architectures and publishes the image:
+
+   ```yaml
+   name: Publish
+   on:
+     push:
+       tags: ["v*"]
+   permissions:
+     contents: read
+     packages: write
+   jobs:
+     publish:
+       runs-on: ubuntu-latest
+       steps:
+         - uses: actions/checkout@v4
+         - uses: docker/setup-qemu-action@v3
+         - uses: docker/setup-buildx-action@v3
+         - uses: docker/login-action@v3
+           with:
+             registry: ghcr.io
+             username: ${{ github.actor }}
+             password: ${{ secrets.GITHUB_TOKEN }}
+         - uses: docker/metadata-action@v5
+           id: meta
+           with:
+             images: ghcr.io/${{ github.repository }}
+             tags: |
+               type=semver,pattern={{version}}
+               type=semver,pattern={{major}}.{{minor}}
+         - uses: docker/build-push-action@v6
+           with:
+             context: .
+             platforms: linux/amd64,linux/arm64
+             push: true
+             tags: ${{ steps.meta.outputs.tags }}
+             labels: ${{ steps.meta.outputs.labels }}
+   ```
+
+3. **Release:** bump `version` in `/provider/info`, then tag and push.
+
+   ```bash
+   git tag v0.1.0 && git push origin v0.1.0
+   ```
+
+4. **Make the image public.** GitHub creates new packages as private. Open the package from your
+   profile's **Packages** tab, then **Package settings > Change visibility > Public**.
+
+5. **Write the README people need:** what the provider covers, a Compose snippet with a pinned
+   version, the address to enter in BookOrbit, its environment variables, what it sends to its
+   source, and any known gaps.
+
+6. **Tell people about it** in a
+   [Community Discussion](https://github.com/bookorbit/bookorbit/issues/new?template=discussion.yml).
+   To have it offered under **Available to install** in every BookOrbit, open a pull request that
+   adds it to `directory.json` in
+   [bookorbit-metadata-providers](https://github.com/bookorbit/bookorbit-metadata-providers).
+
+### Versions
+
+Use semantic versions and tag each image with its full version (`0.1.0`), its minor line (`0.1`)
+and, if you like, `latest`. Tell users to pin a version, so an update never surprises them.
+
+Once people use your provider:
+
+- Keep its key forever.
+- Keep answering for ids you issued before. BookOrbit stores them on people's books and looks them
+  up again on every refresh; an id that suddenly returns 404 tells BookOrbit the book is gone.
+- Bump `version` with every change to your answers.

+
+### `GET /search`
+
+BookOrbit sends `query` (the title), `author` and `mediaType` (`book` or `audiobook`), plus `isbn` and
+`limit` if you listed them in `searchParams`. It only searches when it has a title or an ISBN.
+
+Answer with your matches, best first:
+
+```json
+{
+  "matches": [
+    { "providerId": "1692", "title": "BERSERK", "authors": ["MIURA Kentaro"] }
+  ]
+}
+```
+
+### `GET /book/{id}`
+
+The `id` is one of your `providerId` values, URL-encoded. Answer with one book in the same shape as
+a match, or `404` when it does not exist.
+
+### A book
+
+| Field                                | Notes                                                              |

+
+| You answer                            | BookOrbit                                                 |
+| ------------------------------------- | --------------------------------------------------------- |
+| `200`                                 | Uses the answer. An empty `matches` list means none found |
+| `404` from `/book/{id}`               | Treats the id as gone                                     |
+| `429` with `Retry-After`              | Waits that long before asking again                       |
+| `401`, `403`                          | Reports the authorization header as refused               |
+| Anything else, a timeout, or bad JSON | Counts a failure, and may answer from its cache           |
+
+BookOrbit waits as long as the admin set for the provider: 10 seconds by default, between 2 and 30.
+It reads at most 2 MB of an answer and the first 50 matches, and follows at most 3 redirects.
+
+### Icon and colour
+
+BookOrbit downloads the image at `avatarUrl` when the provider is added, tested, or rechecked every
+six hours, and serves its own copy, so readers' browsers never contact you. It keeps PNG, WebP, JPEG,
+GIF and ICO images up to 256 KB, judged by the file's contents; SVG is never kept. A square image of
+64 pixels or more looks best. `color` must be six hex digits, such as `#2c98cd`, or BookOrbit ignores
+it. Without an icon BookOrbit shows your initials; without a colour, a neutral one.
+
+## FAQ
+
+**Do I need to change BookOrbit?** No. An admin adds your provider by its address.
+
+**Can one container serve several providers?** Yes. Serve each under its own path, such as
+`http://pack:8080/goodreads/` and `http://pack:8080/audible/`, each with its own key, and add each
+address separately.
+
+**Can I see what BookOrbit asked?** Log the request path and status, not the query: the query is
+someone's reading.

+# External Metadata Providers
+
+BookOrbit comes with its own metadata sources: Google Books, Goodreads, Hardcover and others. When
+your library needs something they do not cover well, such as manga, Chinese books or Russian-language
+science fiction, you can add an **external provider**: a small service that runs beside BookOrbit and
+answers its metadata searches.
+
+Once added, an external provider works like a built-in source. It shows up in manual search, Book
+Dock, auto-fetch and library refresh, it can fill field rules, and it gets its own icon and colour
+wherever it appears. Adding one needs no BookOrbit update.
+

+Their source, and what each one returns, is in
+[bookorbit-metadata-providers](https://github.com/bookorbit/bookorbit-metadata-providers). To make
+your own, see [Building a Metadata Provider](BUILDING_METADATA_PROVIDERS.md).
+
+### LubimyCzytac and Aladin used to be built in
+
+Neither is built into BookOrbit any more. Nothing on your books is lost: their ids and links stay
+where they were. Field rules that name either one skip it, and **Settings > Metadata > Providers**
+says what to do.
+
+- **LubimyCzytac** now runs as an external provider. Run its image and add it as below; field rules
+  that name it pick up where they left off.
+
+  ```yaml
+  services:
+    lubimyczytac:
+      image: ghcr.io/bookorbit/lubimyczytac-provider:0.1.0
+      restart: unless-stopped
+  ```
+
+- **Aladin** is retired. Aladin stopped issuing Open API keys on 4 September 2026 and ends the API on
+  30 October 2026, with no replacement, so there is no provider to run. Take it out of your field
+  rules. The Aladin key BookOrbit stored was deleted when it updated.
+
+## Set one up
+
+**Settings > Metadata > Providers** has two tabs: **Built-in** for the sources BookOrbit ships with,
+and **External** for the ones you run. Under **Available to install**, the External tab lists the
+ready-made providers with a **Copy Compose** button and an **Add** button that fills in the address
+for you, so steps 1 to 3 below are mostly done for you.
+
+1. **Run the provider next to BookOrbit.** Add it to the same Docker Compose file, so the two share
+   a network. It needs no ports published and no volumes:
+
+   ```yaml
+   services:
+     mangabaka:
+       image: ghcr.io/bookorbit/mangabaka-provider:0.1.0
+       restart: unless-stopped
+   ```
+
+   Start it with `docker compose up -d`.
+
+2. **Add it in BookOrbit.** Open **Settings > Metadata > Providers > External** and choose **Add** on
+   its card, or **Add provider** for one that is not listed. The address is the service name and
+   port: `http://mangabaka:8080`.
+
+3. **Turn on Allow private address.** A container beside BookOrbit is on a private network, and
+   BookOrbit refuses private addresses unless you allow it for that provider. Leave it off for a
+   provider hosted on the internet.
+
+4. **Save, then choose Test.** A good test shows how many results a sample search found and how
+   long it took. The provider appears in the list with its own icon.
+
+5. **Turn it on.** It now answers manual searches: open a book, **Edit Metadata > Search**, and its
+   results show beside the built-in sources.
+
+6. **Let auto-fetch use it.** A new provider is in no field rule yet. Choose **Use in field rules** to
+   add it to the end of every rule it can fill, or add it to individual rules yourself in
+   **Settings > Metadata > Field Rules**. Move it up in the rules where it should win: for a manga
+   library, MangaBaka belongs ahead of the general sources for title, series and cover.
+
+### Tips
+
+- **Pin a version** such as `0.1.0` rather than `latest`, and update on purpose. After updating,
+  choose **Test** to pick up the new version straight away; otherwise BookOrbit notices within six
+  hours.
+- **Keep it private.** A provider only has to be reachable from BookOrbit. Do not publish its port to
+  the internet unless you also set its `AUTH_TOKEN` (see its README) and enter the same value in
+  BookOrbit's **Authorization header** field.
+- **Authorization headers are stored encrypted** with `BOOK_REQUEST_ENCRYPTION_KEY`, the same key
+  book requests use (see `server/.env.example`). If that key changes, the provider shows **Header
+  unreadable** and is skipped until you enter the header again.
+- **More than one at once is fine.** Each provider has its own key, ids and ratings, and BookOrbit
+  asks each at the pace it asks for.
+
+## What a provider can see
+
+BookOrbit sends a provider the title, author and ISBN of each book it asks about, and the provider's
+own id for a book it has already matched. It sends nothing else about your library or your users.
+A provider passes those details on to the service it gets its data from, so a provider for a public
+site means that site sees which books you look up.
+
+The list under **Available to install** is read from the
+[bookorbit-metadata-providers](https://github.com/bookorbit/bookorbit-metadata-providers) repository
+on GitHub, at most once a day and only when an admin opens the External tab. To keep BookOrbit from
+contacting GitHub for it, set `METADATA_PROVIDER_DIRECTORY_URL=off`; the list that came with your
+version is shown instead.
+
+## Status
+
+| Status            | What it means                                                                     |
+| ----------------- | --------------------------------------------------------------------------------- |
+| Ready             | Working, but turned off                                                           |
+| Active            | Working and turned on                                                             |
+| Last check failed | The six-hourly check failed; it keeps answering with what it last reported        |
+| Unreachable       | Three checks in a row failed; it is skipped until one succeeds. Choose **Test**   |
+| Key changed       | The provider now reports a different identity. Remove it and add it again         |
+| Incompatible      | Something answered at that address, but not a metadata provider BookOrbit can use |
+| Header unreadable | The saved authorization header can no longer be decrypted. Enter it again         |
+
+## Removing a provider
+
+**Remove provider** keeps the ids and ratings it stored on your books and its place in field rules,
+so adding it again later picks up where it left off. **Remove and delete its data** also deletes those
+ids, ratings and its cached answers.
+
+## Troubleshooting
+
+- **"That address is on a private network"**: turn on **Allow private address** for it.
+- **"Could not reach a provider at that address"**: the address is what BookOrbit, not your browser,
+  can reach. Inside Docker that is the service name (`http://mangabaka:8080`); `localhost` would be
+  the BookOrbit container itself. Check the provider is running with `docker compose ps`.
+- **"Answered, but not with usable provider info"**: the address is wrong or points at something
+  else. Open `<address>/provider/info` from the BookOrbit host; a provider answers with JSON that has
+  a `name`. A missing or extra path in the address is the usual cause.
+- **"A provider with the same key is already registered"**: that provider is already added. Each
+  provider can be added once.
+- **Two providers show the same name**: BookOrbit adds the host, such as "FantLab (fantlab:8080)", so
+  they can be told apart.
+- **No results for a book you know is there**: the provider searches by title and author as they are
+  in BookOrbit. For MangaBaka, a title like "Berserk Vol. 3" works; for FantLab, Russian titles find
+  more than English ones.
