Is there an XML standard for Ecommerce Products?

Is there a standard way of transferring product data between e-commerce web sites?

I presume there are several cases where a company wishes to include another companies products inside its store. How then would thi开发者_JS百科s be accomplished?

I presume an XML feed would the way to go, but is there a standard for something along the lines of product name, product code, stock levels, colour options, image filename, price, discount eligibility etc?

I know Magento uses XML to import/export products but is this based on a recognised standard?

I don't know if there is something specific for e-commerce web sites. But definitely, there's something more general to do EDI (Electronic Data Interchange) among businesses. The standard is defined by a NPO called GS1. Look on their website for a standard named EAN-UCC XML.
