Internet Offer Format Internet Offer Format is an is an XML standard for product data exchange in IdoSell Shop online stores. As it is provided under the Creative Commons license, it can and is used in a number of external solutions. Its structure aims to provide an efficient way for exchanging data about products, prices and special parameters. We aim to develop the standard in accordance with actual requirements of the ecommerce landscape by adding only the essential elements to the base format, and creating space for additional information in the form of IOF Extensions.

Most important changes in version 2.6 of the Internet Offer Format are:

In addition to the above, IOF 2.6 comes with the following changes:

  • manufacturer code support (more control over external product codes)
  • ability to set product icons for external marketplace services as well as product icons in groups
  • ability to set the product code displayed on the product details page
  • the full.xml file contains full product size names (as text_id) which were previously available only in sizes.xml
  • product names and descriptions in full.xml are now by default generated in the receiver’s account language and the currency is tied to the default currency set in the supplier’s shop
  • single VAT rate for all prices for a given product
  • improved the way parameter section orders and values are generated

In addition to IOF 2.6 we are also releasing a new version of IAI Downloader 1.20.0.0 which fully supports the new format.
