We are excited to inform the upcoming new Item Spec 4.0 for Marketplace sellers that will improve item setup and maintenance. Item Spec 4.0 is an initiative that aims to modernize Walmart’s Global Data Model. We’ve done a total overhaul from our 3.2 specs and added over several new product and compliance attributes to the spec. We’ve also made many updates to existing attributes, such as enhancing our data definitions, adding much needed closed list values, modernizing attribute names, and organizing attributes in a precise and cohesive manner. All of these changes aim at reducing the complication around item setup and introducing a new maintenance spec to make item management that much easier for our sellers!
