Each of the sketched approaches focuses on specific facets of interest in modelling and analysis of CSNs. Ideas and resulting formalisms of description (formal systems and languages) connected with the approaches are well established in the scientific community. Although some of them are known for several decades, new applications and areas of usage arise constantly. This emphasises the importance of fundamental research for upcoming fields of scientific interest.
The aforementioned representations have shown their practicability in a plethora of application scenarios. By devising specialised instances, they can easily be adapted and handled as flexible tools. Depending on the current area of study, the range of representations can be used in different phases and workpackages. We abstain from giving a detailed introduction into denotations and nomenclatures of the representations here, but rather refer to primary literature mentioned as well as to publications in the context of the ESIGNET project and its members.
