I think either SQL::Schema::FromINI or SQL::Translator::FromINI would be appropriate.

I like the 'FromINI' because it clearly says where the data is coming from. It sounds like it's more or a translator than anything that generates a schema .. a schema generator is much more of an abstract item.

I don't believe it should have 'DBIx' in front of it -- it's not actually part of that class or group, it's more of a preparatory step.
