Parameter¤

Endpoint URI¤

The URI of the SPARQL endpoint, e.g., http://dbpedia.org/sparql

  • Datatype: string
  • Default Value: None

Login¤

Login required for authentication

  • Datatype: string
  • Default Value: None

Password¤

Password required for authentication

  • Datatype: password
  • Default Value: None

Graph¤

Only retrieve entities from a specific graph

  • Datatype: string
  • Default Value: None

Page size¤

The number of solutions to be retrieved per SPARQL query.

  • Datatype: int
  • Default Value: 1000

Entity list¤

A list of entities to be retrieved. If not given, all entities will be retrieved. Multiple entities are separated by whitespace.

  • Datatype: multiline string
  • Default Value: None

Pause time¤

The number of milliseconds to wait between subsequent query

  • Datatype: int
  • Default Value: 0

Retry count¤

The number of retries if a query fails

  • Datatype: int
  • Default Value: 3

Retry pause¤

The number of milliseconds to wait until a failed query is retried.

  • Datatype: int
  • Default Value: 1000

Query parameters¤

Additional parameters to be appended to every request e.g. &soft-limit=1

  • Datatype: string
  • Default Value: None

Strategy¤

The strategy use for retrieving entities: simple: Retrieve all entities using a single query; subQuery: Use a single query, but wrap it for improving the performance on Virtuoso; parallel: Use a separate Query for each entity property.

  • Datatype: enumeration
  • Default Value: parallel

Use order by¤

Include useOrderBy in queries to enforce correct order of values.

  • Datatype: boolean
  • Default Value: true

Clear graph before workflow execution¤

If set to true this will clear the specified graph before executing a workflow that writes to it.

  • Datatype: boolean
  • Default Value: false

SPARQL query timeout (ms)¤

SPARQL query timeout (select/update) in milliseconds. A value of zero means that the timeout configured via property is used (e.g. configured via silk.remoteSparqlEndpoint.defaults.read.timeout.ms). To overwrite the configured value specify a value greater than zero.
