+ description "The Language of Space", connoting universal communication. aUI is built upon a set of proposed universal semantic primes or elements of meaning that are combined – analogous to the atomic elements of the periodic table – to create ‘molecules of meaning.’ Each ‘element of meaning’ is represented by both a morpheme and a phoneme, all of which are motivated by their intuitive relationship to reality. Weilgart found these fundamental concepts to be at such a basic level that they likely could not be defined by any simpler concepts. aUI has 31 morpheme-phonemes each with an associated meaning, i.e. each morpheme = a phoneme = a sememe.

- summary Berkeley DB (BDB) is a software library intended to provide a high-performance embedded database for key/value data. Berkeley DB is written in C with API bindings for C++, C#, Java, Perl, PHP, Python, Ruby, Smalltalk, Tcl, and many other programming languages. BDB stores arbitrary key/data pairs as byte arrays, and supports multiple data items for a single key. Berkeley DB is not a relational database.BDB can support thousands of simultaneous threads of control or concurrent processes manipulating databases as large as 256 terabytes, on a wide variety of operating systems including most Unix-like and Windows systems, and real-time operating systems. BDB was commercially supported and developed by Sleepycat Software from 1996 to 2006. This company was acquired by Oracle Corporation in February 2006, which continues to develop and sell Berkeley DB. Under Oracle's stewardship, "Berkeley DB" has become a common brand name for three distinct products: Oracle Berkeley DB, Berkeley DB Java Edition, and Berkeley DB XML. These three products all share a common ancestry and are currently under active development.
