Description
I want to get data items contained in the selected dataset in internal catalog according to selection criteria defined as SPARQL query.
Preconditions
- at least one dataset in internal catalog with at least one resource available as RDF data exists
How to do it:
- clicks the selected dataset 'Name' in the list of internal catalog records
- list of available resources for a dataset are displayed
- clicks to resource 'Name' of a resource presented as SPARQL endpoint for RDF data
- metadata fields about dataset resource are displayed
- clickable URL of SPARQL endpoint query interface is available with:
- preselected graph name (Graph IRI): 'http://<hostname>/dataset/<name of the dataset>'
- default SPARQL query: 'select * where {?s ?p ?o} limit 1000'
- clicks to URL of SPARQL enpoint query interface
- pre-filled Graph IRI is displayed (can be modified)
- editable text field dedicated to SPARQL query is displayed
- 'Results format' combo box for results format selection is available
- 'Run query' button is available
- clicks 'Run query' button
- if the query was successful, results are displayed in browser (in case of HTML result format) or downloaded to local file system (in case of other result formats)
- if the query was not successful, SPARQL engine error message is displayed in browser
