<p class="MsoNormal">To those interested in theory and science platforms <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">At the next IVOA interop, April 25-29 (<a href="https://indico.ict.inaf.it/event/1824/">https://indico.ict.inaf.it/event/1824/</a>), the theory interest group will have one session, shared with the grid and web services working group. 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
<a href="https://wiki.ivoa.net/twiki/bin/view/IVOA/InterOpMay2021SPW">https://wiki.ivoa.net/twiki/bin/view/IVOA/InterOpMay2021SPW</a>).
<o:p></o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The details of the program are still to be worked out, please follow the progress on
<a href="https://wiki.ivoa.net/twiki/bin/view/IVOA/InterOpApr2022">https://wiki.ivoa.net/twiki/bin/view/IVOA/InterOpApr2022</a>. And feel free to discuss this on the mailing list or the theory-ig slack channel on ivoa.slack.com.
