There are few default templates for IM or DSE in Accelerators package zip file. Did you verify them?
- Lokesh Kumar
the templates you are mentioning are about GDSN Data Pools (DSE: & IM).
They seem to have nothing to do with Magento data imports.
we are providing some sample templates within Product 360 Accelerator package (i.e. ECCnet, GDSN), that´s correct. Unfortunately there are no Magento pre-configured data imports as part of the standard package but could be requested via Informatica Professional Services (IPS). I hope it helps.
All the best
