200 Databases 700 People 100 Institutions Total investment to date €308 million Annual cost €35 million About 1/3 of responders report NO costs 60% of polled databases didn’t respond It is almost certain that the non-responders are smaller on average 60 million web hits per month The EBI reports €22 million per year directly on databases Certainly EBI’s reporting is more complete than other sites Total European effort
The cost of the science supported by the infrastructure is possibly two orders of magnitude higher than that of the proposed ELIXIR infrastructure Comparative cost

Scope and nature of database provision some reflections from the committee
The committee endorsed ELIXIR’s biomolecular focus Cautioned against over-expansion of that focus For example, connect to medical data, rather than expanding the scope of ELIXIR Shared ontologies will be crucial to this, and should receive appropriate attention within ELIXIR Biologically active small molecules are in scope important to have public domain chemical resources available ELIXIR scope
Core databases are complete collections of universal scientific value Core databases require that the providing institution takes on long-term responsibility Investigator-led databases scope and persistence reflects the interests research group not core funded from appropriate research funds Examples of core databases: UniProt, EMBL-Bank, MSD, Ensembl and ArrayExpress Non-core databases can be candidates for core Mechanism to move databases in and out of core To create or discontinue database projects Core and non-core distinction
Support databases are built to support the operation of the core databases or to be used in conjunction with them to increase their value. For example they may provide controlled vocabularies for a range of core databases (say organism names). Investigator-led databases are typically the product of research groups (though they may well be served to external users). Their content reflects the research interests of their provider (E.g., documenting catalytic sites). Specialist databases handle data whose structure cannot easily be represented in the more general database (say immunoglobulins). Derivative/Summarising databases combine and organise data from a range of other databases, such as a non-redundant set of coding sequences. Non-core databases
Where data can be identified to individuals access restrictions associated with confidentiality, consent and ethics must be applied This must not be confused with protectionism Consent and confidentiality
Data discussed in a publication should be made available before or at the time of publication In some domains early publication might actually be a far from complete analysis of a complex data set Even where this is the case the normal rules should apply for biomolecular data These norms apply to “conventional”, “hypothesis-driven” research Projects whose funding is justified by the creation of shared data collections should make their data available as soon as they are useful Data release and publication

We cannot do everything – we will have to review existing databases and consider proposals for new data bases.

Data sharing is the norm in the biomolecular domain ELIXIR should espouse the strongest possible public domain principles (Question ?) Data supported by the infrastructure should be downloadable in their entirety and subject to no restrictions in use and reuse (Question ?) Insistence on acknowledgement is acceptable Prohibiting the distribution of a modified data collection in a form which could be confused with the original is acceptable Service organisations should exist in a research context Collaboration and avoidance of duplication in core data archives essential Creative competition on services desirable Data bases produced by research with primary responsibilities only to their research group are not Elixir and should be identified as such (hobby databases) Elixir data resources must connect with their global context Standardisation and interoperability are crucial Principles & Recommendations
