Pedro Osuna from ESA/ESAC talked about VOSpec. While there was a demo of this tool yesterday in one of the focus sessions, I can't find anything on the web about it. It looks like it hasn't actually been officially released, so despite the pretty pictures, it's pretty hard to get a handle on what it can actually do.
The new ESA VOSpec tool
To be honest, it looks a lot less capable than the Starlink SPLAT tool.
