SEEK is an open-source platform for scientists to store, share, and collaborate on heterogeneous data, models, and standard operating procedures. It was developed by researchers in the UK and Germany to facilitate data sharing across multi-group projects. SEEK allows scientists to organize experiments and data using ISA-TAB standards, interlink related assets, and control access to assets at various stages of research from private to public. Key features include hosting and simulating SBML models, exploring and annotating spreadsheets, and finding expertise and collaborators through people profiles.
