Thanks John but not really.I was specifically looking for research that wasn't based on protocols such as HTTP, URIs and RDF. But that is still in the field of achieving a global interconnected database.
I'll try:de-referencing an identifier en route to a description (some system specific representation of a data structure) at an address dates back to the advent of computing.
For instance SQL RDBMS engines do this using keys (Primary, Foreign etc..). The problem is that these identifiers are literals and de-reference is an act of DBMS engine specific name->address indirection. Which is why ever SQL RDBMS that only implements literals based identifiers or DBMS specific reference types (as per ORDBMS products of yore) is a data silo vector ++
It's also why all applications developed using existing native (relative to host OS and runtime combination) programming language are also data silo vectors, since they also use local (or app specific) mechanisms for name->address indirection and eventual structured data representation, following de-reference.
In a sense, what John is saying to you is as follows:HTTP URIs are identifiers that make all of the above webby i.e., no DBMS specific name->address based indirection, no operating system + programming language specific name->address based indirection, it all just happens via HTTP URI based hyperlinks which are based on open standards (i.e., platform agnostic).
The virtue described above is the kernel of the Web architecture. That's what makes it tick. That's why we have a World Wide Web that's dexterous enough to handle past, present, and future data access and integration challenges without introducing platform specific data silos.
The novelty of HTTP URIs lies in their truly unique ability to enable mass data de-silo-fication, at Web-scale.
I hope this helps.[1] https://www.youtube.com/watch?v=i49_SNt4yfk -- Binky on Pointers (names or "*") and Pointees (addresses "&") [2] http://bit.ly/1rk0s76 -- Recent post about Oracle data-de-silo-fication via HTTP URIs (note: Green Links [local] vs Blue Links [global] )

I know webby standards are implemented so no need to reinvent the wheel, but I think it's healthy to look things from a different prospective; who knows maybe UDP works better for achieving federated queries. Or maybe triples aren't really the only way to represent the real world.

The value of the Linked Data Principles as bound to "Webby" standards is that they are specific and readily implemented; no make believe...

Because I think it's healthy to look at things from a different prospective, I was wondering whether the same idea of a global interlinked database (LOD cloud) was portrayed using other principles, perhaps based on different protocols and mechanisms.
