I'm not sure what those solve. Dynamic Relational (DR) is relational so that one can use SQL on it without big impedance mismatches. Your links appear to be tying to invent a NON-relational version(s) of SQL, but they are too different from SQL and existing RDBMS to be easy to learn.

DR's goal is to match/fit relational, existing RDBMS, and SQL as much as possible, yet still be dynamic. Non-relational databases and non-relational query languages probably will fail at that goal. They deviate from RDBMS too much because they are changing too many things. DR only deviates just enough from traditional RDBMS to get dynamism so that users of RDBMS can easily learn/use it withOUT tossing out most their RDBMS, relational, and SQL knowledge. It just reinvents one nation, not the entire database world.
