I want to get data items contained in the selected publicly available dataset according to selection criteria defined as SPARQL query.

How to do it:
- clicks the selected dataset 'Name' in the list of publicly available catalog records

- 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/{datasetID}', where datasetID satisfies the restrictions described at https://team.eea.sk/wiki/pages/viewpage.action?pageId=107876024
- 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)
