Hi Everbody, Marcelo and I just updated the Direct Mapping document [1]. We finished Section 4: Direct Mapping as rules. We realized that we were being to verbose so we simplified a lot. We also finished the section that was missing: Generating Reference Triples. In summary, the cases that a direct mapping should consider are Table Triples 1) Table has a PK (single or multi) 2) Table does not have a PK Literal Triples 3) Table has a Pk (single or multi) 4) Table does not have a PK Reference triples: Given two tables: r1 and r2 5) Table r1 has a PK (single or multi) and table r2 has a PK (single or multi) 6) Table r1 has a PK (single or multi) and table r2 does not have a PK 7) Table r1 does not have a PK and table r2 has a PK (single or multi) 8) Table r1 does not have a PK and table r2 does not have a PK We have other things on the agenda, so I guess we won't be able to discuss this today. Time permitting, I'll have an implementation ready based on the rules.
