Ying, this might sound like a stupid question, but if you want SQL
features why not pull your CSV into a relational DB table then R2RML
it into RDF (since mappings will allow you arbitrary SQL)?

Hi,
I am looking for a open source software to convert csv file to RDF
based on one pre-defined ontology. Also, this converter should
support complicated SQL queries (e.g., Group BY query and
IF/THEN/ELSE query) while defining the mapping between csv to our
pre-defined ontology.
thanks
