Agreed. I don't like the idea of having formats in the wild which might reasonably be expected to contain triples, or quads and there being no easy way to tell before you start parsing it. Additionally, the ease of parsing is the main selling point of N-T/Q, and no knowing if there will be 3 or 4 columns makes it trickier. FWIW, N-Quads seems quite popular for data.gov.uk data, and N-Triples/N-Quads are good lowest common denominator formats, for bulk dumps and the like. I would like to see an update to make UTF-8 legal though, and some clarity on BASE URI resolution. - Steve -- Steve Harris, CTO, Garlik Limited 1-3 Halford Road, Richmond, TW10 6AW, UK +44 20 8439 8203 http://www.garlik.com/ Registered in England and Wales 535 7233 VAT # 849 0517 11 Registered office: Thames House, Portsmouth Road, Esher, Surrey, KT10 9AD
