Topic: 2-operad

If we have a symmetric monoidal category, and a lax monoidal functor into Cat\mathsf{Cat}, do we get a 2-Operad? Is there a good reference for this?

@Sophie Libkind, I feel like I remember talking to you about this over the summer...

Oh that sounds familiar! But unfortunately I don't remember anything beyond what you already said.

@Owen Lynch what construction are you trying to generalize here?

Given a lax symmetric monoidal functor into Cat\mathsf{Cat}, the monoidal Grothendieck construction gives a symmetric monoidal category, and you can take the underlying operad of that. But that's still just a 1-operad. The maps in the fibers get incorporated into the operations.
