GraphNodeJS

Graph Traversal on top of rdflib.js

API

A GraphNode represents an arbitrary number of nodes in a graph.

A GraphNode has the following properties:

• value
• termType
• node
• nodes
• graph

The first three properties are available only if the GraphNode represents exactly one node.

A GraphNode has the following methods:

• out(predicate)
• in(predicate)
• fetch()
• each(f)
• fetchEach(f)

The first three methods return a Promise for a GraphNode.The each(f)method invokes f once for every represented node with a GrahphNode representing that node as argument and returns a promise that is satisfied when all promises returned by f are resolved. The method fetchEach(f) is identical to each(f) but every node is fetched before being passed to f.

Example

GraphNode($rdf.sym("https://reto.solid.factsmission.com:8443/public/")).fetch().then(folder =>
    { folder.out($rdf.sym("http://www.w3.org/ns/ldp#contains")).each(contained =>
        { console.log(contained.value) });
    });
