SPARQL Query :: British Music Society Concert Ephemera

Query the Linked-Data and let its values Sparkle (aka SPARQL)

Using this page you can query the linked-data in the Greenstone3 triplestore graph using SPARQL query syntax. The default query provided in the text box below is effectively issuing a query that returns everything stored (a bit like matching with the wildcard '*' that some text-based search systems have), limited to show just the first 500 entries that matched.

Use the default query to get a feel for the data that is stored. Feel free to experiment with the syntax to vary what is returned. For example, to view other "slices" of the rows of data returned, change the values of OFFSET and LIMIT. OFFSET controls how many result rows are skipped over before rows are selected. LIMIT controls how many rows are then taken.

Alternatively, you might be interested in experimenting with forms of access to the triplestore through the more powerful, but complex:

Fuseki interface

Or else export the entire triplestore to work on it with whichever Linked Data tools are your preference:

SPARQL Query

For example, the following is a SPARQL query that list how many times each composer/arranger was performed, based on the ephemera gathered together in the DL collection:

PREFIX dc:  <http://purl.org/dc/elements/1.1/>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
PREFIX gsdlextracted: <http://greenstone.org/gsdlextracted#>
PREFIX intermuse:     <http://intermuse.org/catalogue#>

SELECT ?composer_or_arranger(COUNT(?composer_or_arranger) AS ?num_performances) WHERE {
  ?subject intermuse:ComposerOrArranger ?composer_or_arranger.
}
GROUP BY ?composer_or_arranger
ORDER BY DESC(?num_performances)
