# gordf

The gordf module is an RDF library for Go.

## Current features

- Parse N-Triples from file

- Naive memory graph data structure

- Idiomatic querying of the memory graph

- Structs to represent URI and literals (both typed and lang tags)

## Planned features

- Blank Nodes

- Parsing other RDF formats such as Turtle

- Serialise to disk in RDF formats (N-Triple, Turtle, etc)

- Idiomatic representation of CURIES E.g. `rdf:type` -> `RDF{l: "type"}`

## Example usage

```go

package main

import (

	"fmt"

	"github.com/edmondchuc/gordf/parser"

	"github.com/edmondchuc/gordf/rdf"

)

func main() {

	// Create new graph.

	g := rdf.Graph{}

	// Parse triples from file.

	parser.ParseFile(&g, "data.nt", "nt")

	rdfType := rdf.NewURI("http://www.w3.org/1999/02/22-rdf-syntax-ns#type")

	schemaName := rdf.NewURI("http://schema.org/name")

	// Query the graph by looping.

	for triple := range g.Triples(rdf.None{}, rdfType, rdf.NewURI("http://schema.org/Organization")) {

		for triple := range g.Triples(triple.S, schemaName, rdf.None{}) {

			fmt.Println(triple)

		}

	}

	// Add new triples.

	g.Add(rdf.NewURI("https://edmondchuc.com/me"), schemaName, rdf.NewLiteral("Edmond Chuc"))

}

```
