09:00 - 10:30 Primary Keys & Cross References[edit]
Limit foreign key cross references to the same batch of processed resources
Should primary keys be skipped from cell level triple (or k/v pairs) generation?
Alternate structure in JSON mapping output graph if Primary Key is specified
Making `schema` property mandatory for table description objects & explicit identification of schemas
Composite primary keys and foreign key references
