WP6 Plugins: Urban LarKC Event Decider
svn link: https://larkc.svn.sourceforge.net/svnroot/larkc/trunk/plugins/decide/UrbanLarKCEventDecider/
Introduction
The workflow activated by this decider is able to retrieve the events happening in a given city on a given date. The SPARQL query to get the desired results should be in the following form (events in Milan on July 2nd, 2010):
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX rdfcal: <http://www.w3.org/2002/12/cal/icaltzd#>
PREFIX addr: <http://schemas.talis.com/2005/address/schema#>
PREFIX geo: <http://www.w3.org/2003/01/geo/wgs84_pos#>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX skos: <http://www.w3.org/2004/02/skos/core#>
SELECT ?e ?s ?summary ?cat ?desc ?l ?lab ?lat ?lng
WHERE{
?e rdf:type rdfcal:Vevent.
?e rdfcal:summary ?summary.
?e skos:subject ?cat.
?e rdfcal:description ?desc.
?e geo:location ?l.
?l rdfs:label ?lab.
?l geo:lat ?lat.

?e rdfcal:dtstart ?s .
?l addr:localityName "Milan".
FILTER(?s > xsd:dateTime("2010-07-02T00:00:00Z")
&& ?s < xsd:dateTime("2010-07-02T23:59:59Z")).
}The user of this workflow can set both the name of the destination (which will be identified by LarKC by querying Geonames) and the date on which the events are sought.
The events are currently found on those listed by the well-known Web 2.0 service Eventful (http://eventful.com//).
Prerequisites and dependencies
In order to work properly, the Urban LarKC Event workflow needs the configuration of (at least) one of its plugins, namely the ?EventIdentifier, which requires a valid Eventful API key. Further instructions are given in the ?EventIdentifier README file.
