1. 1IASSIST 2009, Tampere Maarten Hoogerwerf Pitfalls of Enhanced Publications

2. Researchers are discovering the enormous potential of the Internet and want to use it to enhance their publications with additional resources such as research data or visualizations. There are currently many ways to construct such 'enhanced publications', but there remain many difficulties that need to be solved before these enhanced publications can be safely implemented on a large scale. DANS, in cooperation with partners from the SURFshare programme, has built a demonstrator of enhanced publications. The demonstrator gives examples of enhanced publications from different scientific disciplines and shows how OAI-ORE can aggregate the different resources of an enhanced publication and how these aggregations can be transformed into user friendly web pages that allow researchers to view- and navigate between them. The goal of this demonstrator is twofold: triggering the researcher to think about their actual needs by showing them what is possible and making repository managers aware of the difficulties that have to be dealt with before enhanced publications can become a common way of publishing. This paper will give an overview of these difficulties. 2Maarten Hoogerwerf African Digital Scholarship and Curation 2009
