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[source]#

Loads a graph from RDF file.

Parameters:: path (Union[Path, str]) -- The path to the RDF file with which the graph will be created.

Examples

>>> from cfpq_data import *
>>> p = download("generations")
>>> g = graph_from_csv(path=p)
>>> path = graph_to_rdf(g, "test.ttl")
>>> generations = graph_from_rdf(path)
>>> generations.number_of_nodes()
129
>>> generations.number_of_edges()
273

Returns:: g -- Loaded graph.
Return type:: MultiDiGraph

graph_to_rdf(graph: MultiDiGraph, path: Path | str) → Path[source]#

Saves the graph to the RDF file by path.

Parameters:

graph (MultiDiGraph) -- Graph to save.
path (Union[Path, str]) -- The path to the file where the graph will be saved.

Examples

>>> from cfpq_data import *
>>> p = download("generations")
>>> g = graph_from_csv(p)
>>> path = graph_to_rdf(g, "test.ttl")

Returns:: path -- Path to the RDF file where the graph will be saved.
