Entraspan has worked extensively with the Automotive Aftermarket Industry Association (AAIA) Aftermarket Catalog Enhanced Standard (ACES) database and encoded data, along with the Product Information Exchange Standard (PIES) data sets. ACES data has become the standard for exchanging product fitment data between manufacturers and resellers, and e-Commerce sites including Amazon and e-Bay. Entraspan wrote a ACES server to handle high performance storage/retrieval of ACES data. An editor was written to make it easier to manage ACES record data for parts.
