Note

This system uses Squish an SQL-like Query-language for RDF. Squish only does conjunctions. This means that all the clauses are implicitly connected by "and". One of the limitations of this approach is that is requires that all of the terms in the subgraph by present for Squish to return any results in a given row.

For this system, Squish requires that you include a ical:description element for each ical:Calendar element, and ical:description and ical:dstart and ical:dend ical:Date objects (with rdfs:label, and ical:hour and ical:minute elements/attributes).

Here's the query that Squish uses:


SELECT ?caldesc, ?desc, ?hour, ?min, ?houre, ?mine 
WHERE 
 (ical::description ?cal ?caldesc) 
 (ical::vevent ?cal ?event) 
 (ical::description ?event ?desc) 
 (ical::dstart ?event ?date) 
 (rdfs::label ?date 2001-05-15) 
 (ical::hour ?date ?hour) 
 (ical::minute ?date ?min) 
 (ical::dend ?event ?datee) 
 (ical::hour ?datee ?houre) 
 (ical::minute ?datee ?mine)
