Transparent data access

JavaScript Proxies enable LDflex processors to translate path expressions to SPARQL queries and resolve them through a query engine (e.g. Comunica)

await [https://julianrojas.org/#me].name

SELECT ?name WHERE {
  <https://julianrojas.org/#me> <http://xmlns.com/foaf/0.1/name> ?name.
}

Support for data writing

LDflex allows for writing/updating knowledge graphs that support SPARQL UPDATE operations such as SPARQL endpoints and Solid pods.

For example this expression:

await [https://julianrojas.solid.org/profile/#me].add('foaf:givenName' , 'Julian');

Will be translated to this SPARQL UPDATE query:

INSERT DATA {
  <https://julianrojas.solid.org/profile/#me> 
    <http://xmlns.com/foaf/0.1/givenName> "Julian".
}

Traverse Linked Data as JS objects

await [https://julianrojas.org/#me].name // "Julián Rojas"
await [https://julianrojas.org/#me].friends.name // ["Ruben Verborgh", "Ruben Taelman", ...]
