atomic-server

The easiest way to share Atomic Data on the web. Demo on atomicdata.dev

• No runtime dependencies, fast, runs on all platforms
• Embedded HTTP / HTTPS / HTTP2.0 server
• Serialization to HTML, JSON, Linked Data (RDF/XML, N-Triples / Turtle / JSON-LD) and AD3

Powered by Rust, atomic-lib, actix-web, Sled and more.

When should you use this

• You want to make (high-value) datasets as easily accessible as possible
• You can afford to create or find an Atomic Schema for your dataset (use atomic-cli new class for this). Example classes here.
• You want to use and share linked data, but don't want to deal with most of the complexities of RDF, SPARQL, Triple Stores, Named Graphs and Blank Nodes.

Getting started

Run using docker

The dockerfile is located in the project root, above this server folder.

• Run: docker run --name atomic-server -p 80:80 -p 443:443 joepmeneer/atomic-server
• Stop: docker stop atomic-server

Install from source

Install Cargo to build from source.

```sh

Clone this repoo

git clone git@github.com:joepio/atomic.git cd atomic/server

Optional, but recommended: Create a new .env using the template.

cp default.env .env

Run the server. It creates a store in ~/.config/atomic/db by default

cargo run

Visit http://localhost

```

Running from cargo

You can also install with cargo install atomic-server, but this binary will also require:

• the /templates directory
• the /static directory

Usage

Check out ./example_requests.http for various HTTP requests to the server.

Set up on own domain

If you want to run Atomic Server on your own VPS + domain, make sure to correctly set the .env. See default.env for a template and explanation of variables.

Use atomic-cli as client

atomic-cli is a useful terminal tool for interacting with atomic-server. It makes it easy to query and edit Atomic Data from the command line. Check it out.

Get individual resources

You can fetch individual items by sending a GET request to their URL.

```sh

Fetch as AD3 triples

curl -i -H "Accept: application/ad3-ndjson" https://atomicdata.dev/properties/shortname

Fetch as JSON-LD

curl -i -H "Accept: application/ld+json" https://atomicdata.dev/properties/shortname

Fetch as JSON

curl -i -H "Accept: application/json" https://atomicdata.dev/properties/shortname

Fetch as Turtle / N3

curl -i -H "Accept: text/turtle" https://atomicdata.dev/properties/shortname ```

Query the store with Triple Pattern Fragments

```sh

Fetch as AD3 triples

curl -i -H "Accept: application/ad3-ndjson" "https://atomicdata.dev/tpf?subject=&property=&value=description" ```

HTTPS Setup

You'll probably want to make your Atomic Data available through HTTPS. You can use the embedded HTTPS / TLS setup powered by LetsEncrypt, acme_lib and rustls. To setup HTTPS, we'll need to set some environment variables. Open .env and set:

env ATOMIC_EMAIL=youremail@example.com ATOMIC_DOMAIN=example.com

Run the server cargo run. Make sure the server is accessible at ATOMIC_DOMAIN at port 80, because Let's Encrypt will send an HTTP request to this server's /.well-known directory to check the keys. It will now initialize the certificate. Read the logs, watch for errors.

HTTPS certificates are automatically renewed when the server is restarted, and the certs are 4 weeks or older.

Testing

```sh

This also makes sure that cli and server work, plus it test the db feature

cargo test --all ```

Performance benchmarking

```sh

Install drill

cargo install drill drill -b benchmark.yml --stats ```
