Meta Database

The metadatabase is a database in MetaKraftwerk that you can use to store and transform metadata. There are various ways to load metadata from external sources into the metadatabase. It is stored in simple relational tables. Once the metadata is loaded, it can be evaluated and further processed using SQL. It is possible to define SQL-based views that perform transformations on the metadata. The ultimate goal of this is to prepare metadata so that it can be used as instance metadata.

The following chapters describe the functionality of the metadatabase in detail.
