cfpq_data.graphs.readwrite.rdf

Read (and write) a graph from (and to) RDF file.

Functions

graph_from_rdf(path)	Loads a graph from RDF file.
graph_to_rdf(graph, path)	Saves the graph to the RDF file by path.

graph_from_rdf(path: Path | str) → MultiDiGraph

Loads a graph from RDF file.

Parameters:

pathUnion[Path, str]

The path to the RDF file with which the graph will be created.

Returns:

gMultiDiGraph

Loaded graph.

Examples

>>> from cfpq_data import *
>>> import pathlib, tempfile
>>> d = pathlib.Path(tempfile.mkdtemp())
>>> p = d / "g.csv"
>>> _ = p.write_text("0 1 a\n1 2 b\n")
>>> g = graph_from_csv(path=p)
>>> path = graph_to_rdf(g, d / "g.ttl")
>>> generations = graph_from_rdf(path)
>>> generations.number_of_nodes()
3
>>> generations.number_of_edges()
2

graph_to_rdf(graph: MultiDiGraph, path: Path | str) → Path

Saves the graph to the RDF file by path.

Parameters:

graphMultiDiGraph

Graph to save.

pathUnion[Path, str]

The path to the file where the graph will be saved.

Returns:

pathPath

Path to the RDF file where the graph will be saved.

Examples

>>> from cfpq_data import *
>>> import pathlib, tempfile
>>> d = pathlib.Path(tempfile.mkdtemp())
>>> p = d / "g.csv"
>>> _ = p.write_text("0 1 a\n1 2 b\n")
>>> g = graph_from_csv(p)
>>> path = graph_to_rdf(g, d / "g.ttl")
