Computer networks and large-scale systems are growing and becoming increasingly hard to manage, specially in the software front, but also in hardware, and their management information more complicated and hard to integrate in a seamless manner. This paper presents a framework that a) allows the extraction of configuration from its original format, b) models it (including relations and inheritance) via the CIM object-oriented information model, and c) persists and retrieves configuration transparently, independently of the repository, and retaining schema constraints. These steps are facilitated by standard, declarative XSLT templates that allow fast and natural adaptation to new configuration domains, allowing the integration and representation of all configuration information.
