To read an Esri Geodatabase that contains ArcFM (Telvent Miner & Miner) objects requires the ArcFM Object Reader. There is no licensing requirement for the ArcFM Object reader. The usual FME & Esri Geodatabase install and licensing requirements do apply.

The ArcFM Object Reader can be downloaded from the Telvent (Miner & Miner) website:
