Abstract: According to an aspect, a method includes receiving an availability resource from a first computing device associated with a studio entity, where the availability resource includes information about a media content item to be available on a media platform. The method includes storing the information of the availability resource in a database and receiving a package submission from a second computing device associated with a post-production house (PPH) entity, where the package submission includes media manifest core (MMC) data and one or more media assets associated with the media content item. The method includes executing a plurality of processing operations, including an error operation, on the package submission, using the availability resource and/or the MMC data, and, in response to determining that the error operation has resulted in an error, transmitting an error notification to the first computing device and/or the second computing device.
