how to come to essential components & services?

Analyze Data Practices

3Data Practices I (120 interviews etc.)

4Data Practices II – EUDAT federation

Community CentersCommon Data Centers

projects to push limits and raise awareness

5Data Practices II – split of functions

physical layer operations are trivial – know how to do it “logical layer” operations are complex due to relations, etc. all LL information needs to be aggregated and we need to have

a secure access layer around it

a few side remarks

• these are all federated approaches

• some have various use cases (one selected)

• 3 is more of an IT framework applied by many

• description of state very vague indication

• 5 marked red need another round of interaction

much already out there but ...

... why does it cost months

• to federate and integrate data

• to make data interoperable

... need to harmonize, raise trust & value

... make it ready for machines

4 use cases (max 10 min) with the following goals understand whether we get what we want to get

(common components/services) discuss whether we need to adapt the template

Zhu Dieter Sean Giuseppe Ed

discuss how to move on with use cases & analysis discuss my first look on C/S (?) update of existing and appearance on wiki (deadline) deadline for first round (when, whom to motivate, ?) virtual meeting for a discussion on analysis (when?)

at P6 (September) a first document with analysis

What to do today

Did we forget something?

17Data Practices I – Survey

~120 Interviews/Interactions 2 Workshops with Leading Scientists (EU, US)

too much manual or via ad hoc scripts too much in Legacy formats (no PID & MD) there are lighthouse projects etc. but ... DM and DP not efficient and too expensive

(Biologist for 75% of his time data manager) federating data incl. logical information much too expensive hardly usage of automated workflows and lack of

reproducibility

• is DI research only available for Power-Institutes

• pressure towards DI research is high, but only

some departments are fit for the challenges

• Senior Researchers: can’t continue like this!

• need to move towards proper data organization

and automated workflows is evident

• but changes now are risky: lack of trained

experts, guidelines and support
