A semantic-web approach for modeling computing infrastructures

This paper describes our approach to modeling computing infrastructures. Our main contribution is the Infrastructure and Network Description Language (INDL) ontology. The aim of INDL is to provide technology independent descriptions of computing infrastructures, including the physical resources as well as their network infrastructure. INDL also provides the necessary vocabulary to describe virtualization of resources and the services offered by these resources. We build our infrastructure model upon the Network Markup Language (NML). Although INDL is a stand-alone model, it can be easily connected with the NML model. In this paper we show how INDL and NML are used as a basis for models used in three different applications: the CineGrid infrastructure, the Logical Infrastructure Composition Layer in the GEYSERS EU-FP7 project and the NOVI federation platform. Furthermore, we show the use of INDL for monitoring energy aspects of computing infrastructures and its application for workflow planning on computing infrastructures.
