My humble 2 CENTS on

Open Data


I) Thou shalt … Know your Data

•  Make the Scientists aware of … •  Understand your data assets:

•  How was it collected/generated? •  How is it formatted? Is formatting consistent? •  How is it stored? •  Are there missing values? If so, which ones, why? •  Where/how can you process it? •  Are there duplicated values, codes?

•  Over 80% of time is spent cleaning data •  Missing metadata

•  Provenance & versioning •  How can experiments be re-done?

II) Thou shalt … Provide Tooling

•  Make the Scientists aware of … •  This is not a one-size-fits-all process •  Many Open Source Software & libraries •  Consider security and privacy issues •  Find an IT-partner within your organization

III) Thou shalt … Embrace Open Access by Default

•  Make the Scientists & the Management Board aware of … •  The importance of having an E2E metadata workflow in

place, i.e. & a.o., for each publication have your Authors & Organizations rigidly formalised (thus, formalise the metadata at the Source)
