Abstract
Topic maps are a new ISO standard for describing knowledge structures and associating them with information resources, a solution for organizing and accessing large and continuously growing information pools (1). They are dubbed as the 'GPS of the information universe'. One possibility to permanently store Topic Maps is using Relational Databases. In this document I present a possible database schema that allows to store Topic Maps.There are general rules to map DTDs to databases (2) but here I tried to build something ad hoc for Topic Maps. The result is a bit naive and cluttered (Figure 1). I was hoping I could find out a more elegant solution. If you have any suggestion or you know better database model please let me know.
