Various embodiments describe controlling usages of channels of a user experience ecosystem. A computer system provides a user interface to a computing device, generates data entries based on user interactions with the user interface, and stores the data entries in a data store. The data entries identify the channels and specify dependencies between the usages of the channels. The computer system adds, to the data store, identifiers of storage locations of content. The computer system provides, to channel systems, access to the data entries and the identifiers of the storage locations in the data store. A usage of a channel by a channel system includes a content publication based on the data entries and the identifiers of the storage locations. The usage of this channel is coordinated with a usage of a different channel by a different channel system based on the dependencies specified in the data entries.
