I spent a good part of my research time talking out Gaia projects with Dustin Lang. We are thinking about what it would require to put together the full match of the Gaia First Data Release to all existing all-sky or near-all-sky catalogs. Or do forced photometry? The idea is to get together everything we would need to exploit the data, photometrically (and perhaps spectroscopically). If we did it right, we could be a better source for the Gaia data than ESA itself. I also spent time today writing about data-driven, interpretable, nucleosynthesis models.
