Human Use Case 1: Viewing the RDF Description of a URI
Human Use Case 2: Linked Data Browsing Starting from a URI
Machine Use Case: Getting the RDF Description of a Resource
If the URI is dereferenceable, e.g., minted at the http://ldf.fi domain, just input the URI in a browser or use it in your favourite software. For example: URI=http://ldf.fi/finlex/laki/p35. If the URI is described in this LDF service you can use the URI template http://ldf.fi/SERVICE/data?uri=URI no matter whether the URI is dereferenceable or not: just input the URI in the form below:
SPARQL Endpoint: http://ldf.fi/poi/sparql
Queries are represented using the URI template: http://ldf.fi/SERVICE/sparql?query=QUERY

SPARQL Service Description
Get the description in RDF. (Notice: A service description is not available for all datasets - then empty description is returned. If you open the link in browser you are directed to a SPARQL query form instead of the RDF description. You can access the service description by making an HTTP query without an Accept header (e.g. curl).) LDF uses W3C SPARQL Service Description recommendation for this.Visualization
