Hi All, I'd suggest that a high percentage of the worlds RDF data is being published untyped, where plain literals are used as rather than typed literals "12.2" vs "12.2"^^xsd:decimal, and also (to a lesser extent) "strings as"^^xsd:string's. Until today, I had assumed that it was pretty "safe" to, upon parsing, turn xsd:strings in to plain literals / pull the datatype from the range of a property and turn the object in to the correct type. However, it's been suggested to me today that this probably isn't a good thing / "the right thing" to do. And thus, should I be avoiding implementing this feature, and additionally what are the reasons *not* to do this. An example: Ontology contains.. ex:prop rdfs:range xsd:decimal . "data" contains.. :foo ex:prop "12.2" . What reason would there be not to just infer/pull the type and convert to a typed literal? Best, Nathan seeAlso: http://www.w3.org/TR/rdf-plain-literal/ http://www.w3.org/DesignIssues/InterpretationProperties.html
