OxJSON-LD is a parser and serializer for [JSON-LD](https://www.w3.org/TR/json-ld/).
The entry points of this library are the two [`JsonLdParser`] and [`JsonLdSerializer`] structs.
The parser is a work in progress.
Only JSON-LD 1.0 is supported at the moment, JSON-LD 1.1 is not supported yet.
The parser supports two modes:
- regular JSON-LD parsing that needs to buffer the full file into memory.
- [Streaming JSON-LD](https://www.w3.org/TR/json-ld11-streaming/) that can avoid buffering in a few cases.
- To enable it, call the [`with_profile(JsonLdProfile::Streaming)`](JsonLdParser::with_profile) method.
Usage example counting the number of people in a JSON-LD file:
```rust
use oxrdf::{NamedNodeRef, vocab::rdf};
use oxjsonld::JsonLdParser;
let file = br#"{
"@context": {"schema": "http://schema.org/"},
"@graph": [
{
"@type": "schema:Person",
"@id": "http://example.com/foo",
"schema:name": "Foo"
},
{
"@type": "schema:Person",
"schema:name": "Bar"
}
]
}"#;
let schema_person = NamedNodeRef::new("http://schema.org/Person").unwrap();
let mut count = 0;
for triple in JsonLdParser::new().for_reader(file.as_ref()) {
let triple = triple.unwrap();
if triple.predicate == rdf::TYPE && triple.object == schema_person.into() {
count += 1;
}
}
assert_eq!(2, count);
```
