Ugo, there is no such metadata table. What Jody is referring to is the index metadata, which contains some hints for structuring the index. I've never stumbled into a real world setup that has valid bbox information in that. In theory we could add a flag to the datastore factory that tells the datastore to trust that information, but first we lack the machinery discussed here: http://jira.codehaus.org/browse/GEOT-2572 Once that is setup I'll gladly accept patches for Oracle NG in that direction. > BTW, am I right to assume that passing a schema to my data store factory > will only list my tables, whereas passing no schema will allow me to > look up every table in the db? (Again, I specifically mean the Oracle DS.) Correct, thought without a schema there will be troubles if you have two tables with the same name around.
