* [email protected] | | Explicit constructors/converters + ability to specify data type | during TM authoring can help to increase query engine efficiency. Hmmmm. Possibly. I agree that the more information the query processor can infer at compile-time, the more efficient it can be. The question is how much information explicit constructors add. To be honest, I'm not sure of the answer. I don't think there's any question that having type information in the TM can help efficiency, but I think that's a job for TMCL. | BTW, in this case efficient querying can be done even without TMCL | if TM author uses "typed" data. If you mean that the typed data is included directly in the TM, I agree, but for literals in the query one can often infer the type from the operations performed (or from the syntax of the literal). -- Lars Marius Garshol, Ontopian <URL: http://www.ontopia.net > GSM: +47 98 21 55 50 <URL: http://www.garshol.priv.no >
