An implementation of the [JSON-LD] standard for Elixir and [RDF.ex].
The API documentation can be found [here](https://hexdocs.pm/json_ld/). For a guide and more information about RDF.ex and it's related projects, go to .
## Features
- fully conforming JSON-LD 1.0 API processor
- JSON-LD reader/writer for [RDF.ex]
- tests of the [JSON-LD test suite][] (see [here](https://github.com/rdf-elixir/jsonld-ex/wiki/JSON-LD.ex-implementation-report) for a detailed status report)
## TODO
- [JSON-LD Framing]
- [JSON-LD 1.1] support
## Installation
The [JSON-LD.ex](https://hex.pm/packages/json_ld) Hex package can be installed as usual, by adding `json_ld` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[{:json_ld, "~> 0.3"}]
end
```
## Usage
### Expand a document
```elixir
"""
{
"@context":
{
"name": "http://xmlns.com/foaf/0.1/name",
"homepage": {
"@id": "http://xmlns.com/foaf/0.1/homepage",
"@type": "@id"
}
},
"name": "Manu Sporny",
"homepage": "http://manu.sporny.org/"
}
"""
|> Jason.decode!
|> JSON.LD.expand
```
produces
```elixir
[%{"http://xmlns.com/foaf/0.1/homepage" => [%{"@id" => "http://manu.sporny.org/"}],
"http://xmlns.com/foaf/0.1/name" => [%{"@value" => "Manu Sporny"}]}]
```
### Compact a document
```elixir
context = Jason.decode! """
{
"@context": {
"name": "http://xmlns.com/foaf/0.1/name",
"homepage": {
"@id": "http://xmlns.com/foaf/0.1/homepage",
"@type": "@id"
}
}
}
"""
"""
[
{
"http://xmlns.com/foaf/0.1/name": [ "Manu Sporny" ],
"http://xmlns.com/foaf/0.1/homepage": [
{
"@id": "http://manu.sporny.org/"
}
]
}
]
"""
|> Jason.decode!
|> JSON.LD.compact(context)
```
produces
```elixir
%{"@context" => %{
"homepage" => %{
"@id" => "http://xmlns.com/foaf/0.1/homepage",
"@type" => "@id"},
"name" => "http://xmlns.com/foaf/0.1/name"
},
"homepage" => "http://manu.sporny.org/",
"name" => "Manu Sporny"}
```
## RDF Reader and Writer
JSON-LD.ex can be used to serialize or deserialize RDF graphs by using it as a RDF.ex reader and writer.
```elixir
dataset = JSON.LD.read_file!("file.jsonld")
JSON.LD.write_file!(dataset, "file.jsonld")
```
When a context is provided via the `:context` option (as a map, a `RDF.PropertyMap` or a string with a URL to a remote context), the document gets automatically compacted on serialization.
```elixir
JSON.LD.write_file!(dataset, "file.jsonld", context: %{ex: "https://example.com/"})
JSON.LD.write_file!(dataset, "file.jsonld", context: "https://schema.org/")
```
## Pretty printing
Pretty printing is possible on all writer functions with all the formatter options of [Jason](https://hexdocs.pm/jason/Jason.Formatter.html#pretty_print/2), the underlying JSON encoder, to which the given options are passed through.
```elixir
JSON.LD.write_file!(dataset, "file.jsonld", pretty: true)
JSON.LD.write_string(dataset, "file.jsonld", pretty: [indent: "\t"])
```
