+A Table Dialect descriptor `MAY` have the `namespace` property that `MUST` be a string; undefined by default. This property specifies a database schema (namespace).

+For example, the database with the tables below:

+raw.table
+cleaned.table

 ## Excluded
 
 Table Dialect has nothing to do with the names, contents or types of the headers or data within the CSV file (see [Table Schema](/standard/table-schema/) instead), only how it is formatted. However, Table Dialect does allow the presence or absence of a header to be specified, similarly to [RFC4180](http://www.ietf.org/rfc/rfc4180.txt).
