RDF123 at ISWC
Just saw a presentation on RDF123. This is a framework in two parts for exposing spreadsheets as rdf. First part is a protocol for writing an RDF file that explains how the spreadsheet should be transformed into RDF—eg, that depending on whether cells in a given “professor” column “yes” or “no”, the rdf should say “professor” or “student”. It gives you an expression language for specifying the values of certain properties by e.g. concatenating or otherwise transforming various cells. The second part is a graphical user interface for authoring these transformations. Compare to babel—babel will take any spreadsheet and transform it to rdf, but there’s no way to guide that transformation effectively.
