aiiinotate

aiiinotate is a fast and lightweight annotation server for IIIF.

• aiiinotate relies on nodejs/fastify and mongodb
• provides a REST API to read/write/update/delete IIIF annotations and index manifests.
• is distributed as an NPM package, can be used through NPM or Docker
• is built for scalability and speed: in benchmarks aiiinotate stores millions of annotations and its response times are always between $\frac{1}{10}$ and $\frac{1}{100}$ seconds

NOTE: currently, only annotations following the IIIF presentation API 2.0 and 2.1 are supported.

PROD USAGE

Install

1. install mongodb (see dev installation script for help and checkout the official installation guide)

2. install aiiinotate

npm install aiiinotate

Env definition

Basic definition

Copy config/.env.template to .env and edit it.

Runtime env sourcing

aiiinotate runs in a subproicess and won't inherit variables from a plain bash source call. Use either of these instead:

1. dotenvx (recommended):

npx dotenvx run -f /path/to/.env -- aiiinotate <command>

2. manual export:

set -a && source /path/to/.env && set +a
aiiinotate <command>

For clarity, we omit env sourcing from the below commands.

Setup the app

1. start mongod

sudo systemctl start mongod

2. create and configure the database

aiiinotate migrate apply

Usage

All commands are accessible through a CLI (./src/cli).

Run the app

aiiinotate serve prod

Run the CLI

The base command is:

aiiinotate -- <command>

It will give full access to the CLI interface of Aiiinotate. Run aiiinotate --help for more info.

Use the CLI to:

• import data
• export data
• apply and manage migrations

For more information, see the CLI docs.

For a Mirador integration, see the reference implementation (aiiinotate + MongoDB + Mirador 4 + MAE bundled in a single docker-compose)

---

DEV USAGE

Install

# clone the repo
git clone git@github.com:Aikon-platform/aiiinotate.git

# move inside it
cd aiiinotate

# install mongodb
bash ./scripts/setup_mongodb.sh

# install node
bash ./scripts/setup_node.sh

# install dependencies
npm i

Setup

After installing, some setup must be done

1. setup your .env file after config/.env.template and place it at ./config/.env.

2. start mongod

sudo systemctl start mongod

3. configure the database

npm run migrate apply

Usage

Remember to have your mongodb service running: sudo systemctl start mongod !

Start the app

# reload enabled
npm run dev

Test the app

Note that the tests will probably fail if you set the env variable AIIINOTATE_STRICT_MODE to true.

npm run test

Run the CLI

See the CLI docs for more info:

npm run cli

Use the CLI to:

• import data
• export data
• apply and manage database migrations
