| | The Third Manifesto |
 | | Currently in the design phase, the "Rosetta" DBMS framework is a rigorously defined attempt to completely and uncompromisingly implement all of TTM, and to provide an effective solution for cross-database portability; its core is an API definition, that interchangeable back-ends implement. |
 | | The interface is modelled closely on the semantics of Tutorial D and the other concepts in The Third Manifesto. |
 | | First, relations are the only data-type which flows between components of the system (relvars, widgets, and algebra blocks), although of course strings, integers, doubles, etc. are supported as attribute types. |
