I've reorganized the files to match the "attempts/attempt-1" etc structure we've used for other use cases, so that [R2]RML can be contrasted with Mustache-family approaches, Direct Mapping(s) etc. https://github.com/w3c/csvw/tree/gh-pages/examples/tests/scenarios/events Here are the triples we get out so far... https://github.com/w3c/csvw/blob/gh-pages/examples/tests/scenarios/events/output/_output_attempt-1.nt.txt Here is the mapping file itself: https://github.com/w3c/csvw/blob/gh-pages/examples/tests/scenarios/events/attempts/attempt-1/mapping-events.rml.ttl There's an issue (Anastasia is investigating) in which the 'offers' and 'location' triples are not emitted, even though the Offer and Place entities and their properties are emitted. Everything else looks perfect in terms of matching the expected output, i.e. https://github.com/w3c/csvw/blob/gh-pages/examples/tests/scenarios/events/output/expected-triples.txt Ivan - it would be great to show a Direct Mapping variant here. Should we try to produce it programmatically, or by hand? Dan
