Message text written by Michael Rowley > David, I think you missed my main points. 1) Details matter. I would like to see what the arguments would be to the procedures you mention, so that I can see what queries are possible with those procedures. >>>>>>>>>> OK - I'm actually just thinking <findQualifiers> at this point a la UDDI - and the way a method works - you just pass in a valuelist of business content you are wanting to locate. That being said - all the mechanics of the actual query interface are inside the method blackbox. There is no query syntax mechanics as parameters. This is also the familiar model for a SQL proc - all the query syntax is in the proc and therefore secure. 2) Being able to query against arbitrary tag names (one of your locators) seems to contradict everything you say about limiting what can be queried and being independent of implementation. I suspect that I misunderstand what you mean with that. >>>>>>>>>> OK - this may bust the traditional SQL model since SQL needs everything in columns and tables. In an XML model or an HTML search model its much more familiar method. Search the entire information space for occurances of... Oracle could do this if you stored everything as XMLBlobs. At this point though I'm already thinking of rolling this up into an API method instead - therefore this would go in the 'optional' list, since only an XML based implementation could actually do this -maybe - I'm sure someone will now post the obvious rejoiner that with pre-processing of the entire XML content into a single search index the Oracle database can do this - but that's a stiff bar to raise here - so 'optional' is the correct designation here it would seem. I have not yet argued against the approach that you are trying to put together. I think it _may_ be better than the OQL approach (although I prefer something based on XPath), but I want to see more details for the approach you are proposing. >>>>>>>>>>> Thanks - OK - with that encouragement - back to the API - WP!
