Loader, allows the user to load RDF data using the Wikibase RDF Dump Format to a Wikibase instance. There is a whole tutorial on Loading data to Wikibase available.

Wikibase API Endpoint URL (api.php)

This is the URL of the api.php in the target Wikibase instance. For example https://www.wikidata.org/w/api.php

Wikibase Query Service SPARQL Endpoint URL

This is the URL of the SPARQL Endpoint of the Wikibase Query Service containing data from the target Wikibase instance. For example https://query.wikidata.org/sparql

Any existing property from the target Wikibase instance

e.g. P1921 for Wikidata. This is necessary, so that the used library is able to determine data types of properties used in the Wikibase.

Wikibase ontology IRI prefix

This is the common part of the IRI prefixes used by the target Wikibase instance. For example http://www.wikidata.org/. This can be determined by looking at an RDF representation of the Q1 entity in Wikidata, specifically the wd: and similar prefixes.

User name

User name for the Wikibase instance.

Password

Password for the Wikibase instance.

Average time per edit in ms

This is used by the wrapped Wikidata Toolkit to pace the API calls.

Use strict matching (string-based) for value matching

Wikibase distinguishes among various string representations of the same number, e.g. 1 and 01, whereas in RDF, all those representations are considered equivalent and interchangable. When enabled, the textual representations are considered different, which may lead to unnecessary duplicates.

Skip on error

When a Wikibase API call fails and this is enabled, the component continues its execution. Errors are logged in the Report output.

Retry count

Number of retries in case of IOException, i.e. not for all errors.

Retry pause

Time between individual requests in case of failure.
