Towards Versioning Sustainability Reports

Sustainability reporting is a key issue of sustainability development in companies. Sustainability reports are documents which describe data about different performances of companies. They intend to report and analyse sustainability information to provide sustainable future. During sustainability development, reports have to be versioned to analyse histories of sustainability reports and to present changes and improvements of sustainability data. This paper introduces an approach to versioning sustainability reports by means of delta storage. The approach explains an operation-based, schema generic means to store differences between versions. Differences are represented by a sequence of executable operations which allow for obtaining older versions by applying these to the current version. The approach is applied to versioning sustainability reports within the STORM project. ∗ A German version of this paper was published at 5.
