TerraLID-Community Kick-Off

Thanks to the acquisition of funding in early 2024, the prototypes announced to the community as GlobaLID will be turned into full versions. This event informed about the development of GlobaLID, the planned activities during the funded phase and the vision of TerraLID. Several Regional Editors presented their view on GlobaLID/TerraLID and motivation to contribute.

Date: 14 May 2024
Location: Zoom

The recording of the meeting will be available soon.

Round table 1: Which data and meta-information is crucial?

Introductory talk by I. Villa (Bern): Pb from the millimeter to the planet: what else is usually forgotten?
Topics:
1. Analytical data
2. Geological materials
3. Artefacts – and which ones are suitable as reference data?
4. By-products (e.g., slags, prills, ores from excavation sites)

Round table 2: Standardization of databases

Introductory talk by K. Elger (Potsdam): t.b.a.
Topics:
1. Interconnectivity between different databases: Each group deploys their own data online and develops an API to link other databases. Alternatively, each contributes data to a central database (like GlobaLID) so that all data can be accessed at once?
2. Unique resource identifier (URI) and controlled vocabularies and terminologies; Adoption of unique identifiers, such as the IGSN for samples. Use of thesauri, ontologies, standardized mineral abbreviations, geological period information from e.g., USGS, EarthChem databases; geological time periods vs. orogenic events.

Round table 3: Statistics and visualization

Introductory talk by P. Degryse (Leuven): Perspectives on data dots, biplots, ellipses and model ages
Additional presentation by T. Eshel (Haifa) and N Yahalom-Mack/D. Finn (Jerusalem)
Topics:
1. Visualization, statistic and processing tools, methods – what is really useful and needed by the community? What is required, what would be nice-to-have?
2. Reporting – What is proper reporting?

9:00–13:00: Morning session

Impulse talk by Chr. Keller (Berlin): NFDI4Objects
Presentation of the round table discussions and discussion of their results
Return to the round tables: Define the discussed standards, taking into account the feedback from the plenary

13:00: Lunch break

14:30 – 16:00: Afternoon session, final plenary

Summary of the second round of round tables
Discussion about how to proceed, e.g.,
- Follow-up meetings
- Roadmap to the publication and establishment of the community standard
- Extension to other methods and materials

16:00: Closing of the workshop, take-aways and farewell
