When working with scientific publications, a paper has (from the author's perspective) following states:
A. under submission B. accepted for publication C. in press D. final
When showing a paper on a homepage, papers in the states A to D should be shown. When making the data available for OAI, only papers in the state D have to be exported.
Reason: 1. Final bibliographic data such as pages or DOI are only available in state D. 2. Researchers are very proud of their papers. Thus, they want to show them as early as possible
