1. Aalto Data Repository Keijo Heljanko and Mikko Hakala firstname.lastname@aalto.fi

2. Your Current Challenges Aalto University is the largest University in Finland in engineering Data science is one of the focus areas of Aalto, data sets include next generation sequencing, social media, brain images, etc. Aalto is defining its research data management policy and EUDAT is one of the main candidates to implement a research data management platform Currently there is no research data management platform in use, which limits the visibility of Aalto as source for scientific data Also the possibilities of collaboration in sharing data in EU project context through EUDAT is of high interest to our researchers

3. Why EUDAT? EUDAT is an interesting consortium of European players in research data management Already many ongoing collaborations with EUDAT partner CSC in the area of HPC, Cloud Computing, and Big Data Potential possibility to in the future integrate with Finnish national research data management Well established authentication mechanism (CSC Haka) Possibility to work with EUDAT partners on Big Data topics in future collaborations We expect EUDAT to B2SHARE service to be a way to both store and find datasets in the European context We expect B2DROP to be used for inter-project collaborations We would optimally like to be able to use B2SHARE also to store metadata for datasets in closed (University, Department, Project) wide contexts. However, this would require new functionality to B2SHARE for group access right management

4. The expected future impact The Aalto Data Repository pilot can be interesting for other parties looking for solutions for University wide data management We can see that integration to both national level research data management and University level metadata collection will be needed. This will involve metadata import/export Several data sources at Aalto (genomics etc.) can be large 200 GB+ files. Having support for upload and storage of these data sets would be useful Management of closed user groups inside B2SHARE to facilitate early generation of metadata during projects would be useful Moving data between B2DROP and B2SHARE would be convenient. Eventually also integrating big data platforms would be interesting future work
