The English word archive /ˈɑːrkaɪv/ is derived from the French archives (plural), and in turn from Latin archīum or archīvum, the romanized form of the Greek ἀρχεῖον (arkheion). The Greek term originally referred to the home or dwelling of the Archon, a ruler or chief magistrate, in which important official state documents were filed and interpreted; from there its meaning broadened to encompass such concepts as "town hall" and "public records".
The root of the Greek word is ἀρχή (arkhē), meaning among other things "magistracy, office, government", and derived from the verb ἄρχω (arkhō), meaning "to begin, rule, govern" (also the root of English words such as "anarchy" and "monarchy").

In computing, a database is an organized collection of data stored and accessed electronically. Small databases can be stored on a file system, while large databases are hosted on computer clusters or cloud storage. The design of databases spans formal techniques and practical considerations including data modeling, efficient data representation and storage, query languages, security and privacy of sensitive data, and distributed computing issues including supporting concurrent access and fault tolp
A database management system (DBMS) is the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS software additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a database system. Often the term "database" is also used loosely to refer to any of the DBMS, the database system or an application associated with the database.

Kastalia is composed of "knots" which have attributes and relations ("bounds") to other "knots".
Everything (e.g. user, institution, event, presentation slide, fairy tale, musical piece) is a knot.
A knot is a "Ding an sich".
Bounds are predicated. (hello sir Berners-Lee, hello Wikibase, hello "semantic web")
A knot is presented to an observer (e.g. human user) by means of a template.
Combination of a knot, other knots which are bound to it and a template yield "Ding für uns".
