The study of classical modular forms has emerged as a major topic in computational number theory, and the LMFDB is a convenient way to access data and knowledge on these objects.

This success calls for including higher-dimensional analogues, like Siegel modular forms, in the database as well. This workshop will gather experts on Siegel modular forms, algorithmic methods, and the LMFDB to take stock of where we are, discuss the next achievable goals and set further research directions.
