With X.commerce, eBay intends to give merchants and application developers access to a complete stack of e-commerce technologies, including shopping carts, payment services and inventory management, the company Wednesday.

The idea is to let merchants and developers come up with a broad variety of e-commerce applications that meet the increasingly changing requirements and scenarios that shoppers face, including social networking interactions, mobile commerce and others.

, which eBay describes as an "open commerce ecosystem," includes an element called Fabric, an "operating system" that will let developers distribute their wares to eBay merchants.

As part of the X.commerce launch, eBay also announced PayPal Access, an identity system that merchants can implement to let consumers use their PayPal username and password to sign up and log into their e-commerce sites.

Relying on PayPal to handle their customer sign in and authentication will make the process safer and simpler for participating websites, eBay said.
