datatype: * prefixes : map from prefix => iri * selects : list of variable names (with the question mark) * wheres : list of triple patterns := + triple := subject predicate object (string string string) + FILTER (filter_string) + OPTIONAL (pattern, pattern) + UNION (pattern, pattern) * ORDER BY (asc/desc, variable/expression) * LIMIT (integer) * OFFSET (integer) what kind of operators should there be? what should happen in case of conflicts? * always assume that the one on the left is right --- #### Old ideas At first the SPARQL queries were simply represented as strings. Pros: * simple/standard datatype Cons: * not as simple/standard to make complex manipulations to Then use partial queries and some kind of data structure Pros: * easier to manipulate. * easier to define operators Cons: * ?
