TrezorixTrezorix provides infrastructure based on the Reference Network Architecture (RNA). An RNA environment is used for building semantic networks, in wich content items (units of information, like articles or database records) are linked via concepts (units of meaning, like keywords).

RNA environments serve as a retrieval layer, placed between knowledge sources (like file systems, databases, et cetera) and end user applications (like websites). Each RNA environment contains a number of tools, the RNA Toolset, for easy setup and maintenance of semantic networks.
