In 1998 Pan-Sumatra Network for Heritage Conservation (Pansumnet) was founded consisting of heritage societies, individuals, and academic institutions in Sumatra that get involved in the heritage movements of Sumatra Island. It accommodates the need for regional networking to support each other and cooperate since Indonesia is an archipelago country that stretches thousands of islands.

From 2021 and continue to 2024, Pansumnet organizes a monthly webinar (online seminar) with speakers from various heritage groups and heritage organizations from Sumatra, but also with speakers from other places who have works or research related to Sumatra. 

Pansumnet meets and organizes trainings regularly in various places on the Island. In 2018 the Gathering was in Muntok, West Bangka. South of Sumatra.
