Do-a-thon: Development of a distributed data architecture for sharing data in energy systems analysis

Dear all,

I also would like to propose a do-a-thon:

Proposal for:
Do-a-thon
Session Title
Development of a distributed data architecture for sharing data in energy systems analysis.
Session Description
In this session we would like to discuss how a distributed architecture of data bases for energy systems modelling could look like. We have a national funded project for the development and demonstration of a distributed data sharing architecture in energy systems modelling. If we want to be successful with such an approach, we need to be inclusive and want to reach out into the community to disuss our initial thoughs how this could work. We want to learn your perspective and jointly improve our vision how this could look like, to develop something for the benefit of all.
Would you like to be responsible for this Session?
Yes, unfortunately I can only do this on Wednesday due to other appointments
Do you need any special infrastructure for this Session?
No
Do you have any recommendations who could be part of this Session?
Anyone interested in sharing data and make the data more easy to discover and more accessible.

If you are interesed in further information on the project, leave your e-mail here or drop me a message carsten.hoyer-klick@dlr.de, we will set up a newletter from the project.

Session: D.1 A distributed data architecture for sharing energy

Moderation:

Carsten Hoyer-Klick (DLR)

Participants:

Ludwig HĂĽlk (RLI) #OpenScience

Christian Hofmann (RLI)

Simon Worthington (TIB)

Notes:

  • 13:20 Introduction to distributed data infrastructures and Linked Open Data (LOD)

  • Data of peer-reviewed Papers is commonly 2-3 years old

  • Goals:

  • unified description of data

  • proper licensing

  • flexible extendable networked data infrastructure

  • interfaces to GEOSS

  • interfaces to models

Identification of problematic use cases in regards to currently used data infrastructures

A) Please generally state the most problematic data handling related use cases you are confronted with in your every day work? (max. five sentences each)

B) Please select the use case with the highest priority from your above list and describe and/or scetch it in detail. (use back side if necessary)

  1.   Which use case did you select?
    
  2.   Who is the primary actor of the process?
    
  3.   Which other stakeholders / systems are involved?
    
  4.   What triggers the process (pre-conditions)?
    
  5.   What are the goals of the process (post-conditions)?
    
  6.   What information is exchanged between the actors / systems?
    
  7.   What are the individual process steps and their chronological order?
