This will be a brainstorming session focused on defining and getting buy-in on some concrete projects supporting the analysis of what we call cosmological simulations (those that represent and evolve a volume in 3+1 dimensional space-time, whatever its spatial size) on what we have called science platforms (for examples of these look at contributions to the mini workshop during the IVOA interop about a year ago https://wiki.ivoa.net/twiki/bin/view/IVOA/InterOpMay2021SPW).

Within the IVOA context the overarching goal should be to find common practices that could lead to a definition of what constitute interoperability of science platforms.

Such projects would (likely) include hosting simulation data on at least one such science platform, having server-side analysis capabilities near the data, possibly providing search capabilities through a database designed according to the simulation data model (a “SimDB”) with metadata about these simulations.

The session will have a short introduction by GerardLemson proposing the discussion topics.
