4. Init options

The getl.init() function have two optional parameters:

Filters

The filters parameter can be used to filter which function having specific metadatas to parse and which nodes/edges to load.

They are created with the getl.Filter() object:

filters = (
    getl.Filter()
        .add_edges(["AWARDED_FOR", "ACTED_IN"])
        .add_nodes(["Movie", "Person", "Award"])
)
getl.init(filters=filters)

Using these filters in the imdb example, it won't load Director nodes and neither DIRECTED edges.

Callbacks

After each parsing, details are stored in a json file to help the loading in neo4j.

You can also add callbacks after each parsing, to create schema of your graph database.

Two callbacks are pre-made : getl.CallbackOWL() and getl.CallbackSHACL()

They will respectively create an owl schema and a SHACL schema of the graph database when passed :

getl.init(callbacks=[getl.CallbackOWL(), getl.CallbackSHACL()])
