Abstract: An application may provide an export file type definition indicating data objects that may be shared with another application. Sharing data objects between applications may include obtaining the export file type definition from the application and displaying a graphical user interface based at least in part on the export file type definition. Data objects may be selected through the graphical user interface and provided to another application based at least in part on the selection.

Abstract: Electronic marketplaces offer a variety of items to customers over the Internet. Where two or more items are interchangeable with or equivalent to one another, such items may be utilized in the same applications and in the same manner, and marketed and sold together as interchanges or equivalents. Such items may be identified as interchangeable with or equivalent to one another based on a qualitative or quantitative score, which may consider any available information or attributes regarding the items, and may increase or decrease over time as the confidence in a determination of interchangeability or equivalence improves or declines. Moreover, such information or attributes may be identified from any source, such as sellers, vendors or manufacturers of the items, and qualitative or quantitative scores indicative of the accuracy or reliability of such information or attributes may be assigned to such sources, as well.

Abstract: A secure inter-process communication channel is provided to enable application to share data objects. An application may provide an export file type definition indicating data objects that may be shared with another application. Sharing data object between application may include obtaining the export file type definition from the application and displaying a graphical user interface based at least in part on the export file type definition. Data objects may be selected through the graphical user interface and provided to another application based at least in part on the selection.
