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 outline the preliminary model created by the task group, together with first examples that demonstrate how the model is to be used.

With this poster, we want to present the current state of the DCMI Metadata Provenance Task Group, which will wrap up its work at the time of DC-2011. The motivation for a Dublin Core extension for metadata provenance is twofold: Firstly, we want to represent existing metadata provenance information in a simple and unified way that is well suited as an application of Dublin Core. Secondly, we want to enable the provision of provenance information for Dublin Core metadata in a Dublin Core compatible way. Thus, the main objective of the Dublin Core Metadata Provenance Task Group2 is to provide the means and guidelines to model and handle metadata provenance. The approach followed for this task has been to create a model as simple as possible, providing real world examples and mappings to other provenance approaches and comparing the complexity of the outcomes.

In this meeting, we will present the latest version of the provenance domain model, element vocabulary and application profile, i.e. the results of the task group. Open questions will be discussed and the outcome of this meeting will be incorporated in the final deliverables of the task group that is planned to end until the end of the year.
