# RDFa processor library (WIP)

Rust and wasm library to extract rdf statements (in n-triples format) from an html file

based on rdfa annotations.

## Examples

### Rust usage:

```rust

use graph_rdfa_processor::RdfaGraph;

    let html = r#"

    


        
Dan Brickley

	  

    "#;

    let base = "http://example.com";

    let well_known_prefix = Some("http://example.org/.well_known");


    RdfaGraph::parse_str(html, base, well_known_prefix).unwrap()

```

### Node usage:

`npm i @nbittich/rdfa-wasm`

```js

const { html_to_rdfa } = require("@nbittich/rdfa-wasm");

const example = `

           

  

    Test 0224

  

  

    


      


        
git remote add origin [email protected]:nbittich/node-rdfa-wasm-example.gitFoo



        
Bar

      

    

  


`;

console.log(html_to_rdfa(example, "http://data.lblod.info", ""));

```

### Web usage (not published on npm yet):

```js

 

    import init, {html_to_rdfa} from "./rdfa-wasm/pkg/rdfa_wasm.js";

    async function run() {

      await init();

      let html =`

        <div prefix="foaf: http://xmlns.com/foaf/0.1/" about="http://www.example.org/#somebody" rel="foaf:knows">

            <p about="http://danbri.org/foaf.rdf#danbri" typeof="foaf:Person" property="foaf:name">Dan Brickley</p>

	      </div>

      `;

      let base = "http://example.com";

      let well_known_prefix = "http://example.org/.well_known";

      let res = html_to_rdfa(html, base, well_known_prefix);

    }

    run();
