A simple demo app that shows pubs, restaurants, pharmacies, accommodations, museums and - optionally - events in Trentino and Tuscany regions. You can click the location you are interested in to see what can be found nearby. To use event data from a specific resource, use the “events” attribute in the URL in which provide the URI of the resource: app URL/?events=http://sandbox.fusepool.info:8181/ldp/demo/wr-ldpc/Trentino-Events/events-xml-xml-transformed
It uses the following SPARQL endpoint: http://sandbox.fusepool.info:8181/sparql/select
...and works with this SPARQL query:
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX geo: <http://www.w3.org/2003/01/geo/wgs84_pos#>
PREFIX schema: <http://schema.org/>

&& ( ?long >= 10.900897290708068 && ?long <= 11.00089729070807 ) ) }
ORDER BY ?name
...where:
- the last FROM clause is used only if a resource URI is provided in the query string (the other four resource URIs are static)
- eventStart and eventEnd uses exactly what is typed to the input fields on the top left corner
- lat and long come from the position of the marker on the map
