The second workshop of EERAdata is organized as an online webinar and hackathon during November and December 2020. It is dedicated to metadata.


  • Discuss and develop metadata standards for FAIR and open data in the low carbon energy research community. The focus is on the link between metadata and how humans explore data.
  • Identify gaps and needs that hinder their standardized realization and implementation.
  • Jointly work on a community paper and/or join the discussions in use cases. We start with a commented and revised draft. Link to draft of the community paper
Workshop concept of EERAdata

Read & watch aheads

To prepare for the paper writing hackathon, please participate in the preparatory 'Briefing Workshop' or watch the recorded videos. The workshop took place Thursday, 5th of November, 10-12 CET. The workshop introduced recent work on metadata and outlined the tasks and procedures on how to join the writing team for the community.

Join us and collaborate interactively!

Becoming a co-author

Workshop participants are invited to become co-authors of the planned community paper.

How to join the team writing the community paper? Briefing is provided during the preparatory workshop (also recorded). Includes recommendation for read and watch aheads.

The community paper addresses 3 key questions:

  • Q1: How to align mental models of those searching for data with navigation along metadata? What is specific to the energy domain?
  • Q2: What consequences for the construction of domain-specific metadata follow? and how can they be dynamically updated?
  • Q3: What are the recommendations to the low carbon community?

The envisaged output of the paper is:

  • A community-reviewed draft for a low carbon energy ontology in support of metadata,
  • Metadata suggestion cards for low carbon energy researchers,
  • Recommendations on how to proceed.

Invitation to comment the draft before the writing workshop, e.g.:

  • Review of key questions,
  • Suggestions of literature, illustrative cases, metadata perspectives & issues,
  • Suggestions to any section (e.g., Introduction, Method, Discussion of Results, Outlook)
  • Adding snippets of texts,

Any other idea is welcome!

Using above prior comments & contributions provided by 23.11.2020, the EERAdata team will revise the draft before the workshop starts. During the workshop, the discussion & writing of the paper continues in small writing teams. A prior registration to teams is therefore recommended. However, teams can change anytime. The EERAdata team is strongly interested in inviting a large group of contributing authors. It is not only in the interest of the community project as such, but it increases the credibility of the main output - the draft (or road towards) a low carbon energy ontology in support of metadata”.

Co-authorship is granted to active participants of the EERAdata workshop as well as to other contributors to the community paper.

Just have fun!

Read before playing: This is a little memory game where players need to identify triples, that is three tiles that belong to one data set. All of them relate to low carbon energy. Some tiles have the form of a picture, others show metadata descriptions (in various formats) and some are even sound files. So, the game is to have fun, while learning about metadata. Try out if you can find all triples. Note if you have opened 3 tiles and they do not match, all will automatically close. Just as you know it from a real-life memory game. Link

Link to the recording of the session: Link

10:00am - 2:00pm The workshop focuses on metadata, exploring how to link ontologies used for policy-making and those used in research domains. The workshop will use the software "GitMind" to work on the ontology, incorporating suggestions from workshop participants. The participants will form one of the writing teams for the community paper. Link to workshop page with agenda, notes and results

4th December EERAdata participates in International FAIR Convergence 2020 Symposium
15-17 M4M Workshops: Making domain-relevant machine-actionable metadata at scale. There is no FAIR data without machine-actionable metadata. Semantically-rich, domain-relevant, machine-actionable metadata is fundamental for FAIR interoperation of data, algorithms and compute resources. However, FAIR-enabling metadata schema often do not yet exist for many communities and need to be created de novo by the relevant domain experts. In other cases there may be already existing metadata schema but they are difficult to find, assess and reuse. In an effort to support convergence of metadata components, the GO FAIR initiative has launched a systematic and scalable approach to the creation, registration and reuse of machine-actionable metadata called Metadata for Machines (M4M) Workshops. M4M workshops bring together representatives from given scientific communities and FAIR metadata experts to jointly define standards for the metadata that they wish to use in practice. We have found scientists to be highly motivated to develop and use metadata standards through our M4M workshops, and tooling such as the CEDAR Workbench to be effective in the collaborative development of new metadata templates. Thirteen M4M Workshops that have been delivered and in this Session, the most recent workshops (for VODAN Africa, DeiC and ZonMW) will be reviewed. This will be followed by a focused discussion on a proposed M4M workshop for EERA Data Consortium to be run early in 2021.

The agenda, roughly, is:

  • to use the first hour to recap recent M4M accomplishments (VODAN Africa, DeiC, ZonMW COVID Program), and
  • to use the second hour to scope plans for an M4M workshop with the EERA Data Consortium
