The Metadata Provenance Task Group aims to define a data model that allows for making
assertions about description sets. Creating a shared model of the data elements required to
describe an aggregation of metadata statements allows to collectively import, access, use and
publish facts about the quality, rights, timeliness, data source type, trust situation, etc. of the
described statements. In this paper we describe the preliminary model created by the task group,
together with first examples that demonstrate how the model is to be used.
