Original description

Each record has these (hidden) fields:
- rid, as the record id
- version
- class

It would be great to support these hidden field in queries. In this way you can traverse graphs starting from a vertex:

SELECT FROM OGraphVertex WHERE @rid = 3:0 AND TRAVERSE(0,5) (name = 'Luke')

or execute a non-polymorphic query:

SELECT FROM OGraphVertex WHERE @class = 'MyVertex1' OR @class = 'MyVertex2'
