Section 3.1, `rml:iterator` #45

Closed tirrolo closed 6 months ago

In Section 3.1, there is the following sentence:

"In the case of databases, CSV or TSV data sources, the value of rml:iterator is considered a "row" and must not be specified."

The sentence above seems incorrect. First of all, what is it meant by "databases"? Are graph databases databases, or only relational ones are meant here?

Further, for relational databases, rml:iterator CAN be used to express queries according to rml:SQL2008Query reference formulation.

Latest changes included using rml:iterator for SQL query and table names, we probably need to fix 3.1 to better reflect this, thanks for noticing!
