> Relational database systems, hierarchical databases, etc. tend to have a well defined schema. Key-value DBs, BigTable clones, etc. tend to have weakly defined schemas. In fact, a key-value datastore may not have any kind of schema (other than the fact is is key-value).
> Schemas seem like they are local to the connector and should not be needed by the framework. Or, there should be a common Schema format that every connector knows how to decipher.
