## :loudspeaker: Short intro; what does everyone expect from the hack
Also, how much time does everyone plan to invest.
- **SimPEG/discretize**: Dom; Lindsey
- Interoperability of all packages
- GeoH5 or similar
- GemPy <=> GeoH5 https://geoh5py.readthedocs.io/en/latest/
- **PyVista**: Bane
- Reproducible workflow for their research
- Interested in having an underlying "glue" for working across open software
- Recently started at Kitware
- Interesetd in positioning geoscients well for leverage emerging ML technologies
- **GemPy**: Miguel, Alex
- Does all the scientific support, but they also started recently the company. Open basically to help anyone using GemPy.
- Input of GemPy
- Another library, like subsurface, to connect the different tools
- Need for I/O library
- **Fatiando**: Leo (not very much time, weekend is already overbooked | I would be happy to have a shared environment and example use case)
- Load, save, plot, plug into other things is already possible in Python
- NumPy is already a good denominator; NumPy, Pandas, Xarray
- Better bridge between tools.
- Shared environment for all main packages
- Potential point of contact between Gempy and Verde: https://github.com/fatiando/verde/issues/262
- **emg3d:** Dieter
:rocket: Thanks for participating!
## :memo: Plan the hack
- Should there be a main focus (overarching goal) or many foci?
- Two possible approaches: data driven or application (?) driven
- Build use cases first, so we know how the underlying 'thing' could look like.
- Bane did some previous work with the forge geothermal site that he can share (with different kind of geophysical data)
- FORGE data is here: https://gdr.openei.org/search?sort=pub_date_desc
- One general repo or everyone in its own repo?
- Maybe 1 use case repo and a hackmd document for planning and discussion?
- On SWUNG or on subsurface?
- Any other ideas/suggestions from seasoned hackathon attendees?
- List of communities involved
- How shall we handle the time-zone difficulty (meetings in Europe evening)
- How about 1 meeting at 5 or 6pm GMT to hand-off from Europe to US West Coast?
- Need to be good at taking notes somewhere so people know what's going on. These documents seem like a good place (we can archive them to Github easily).
