Technology for a publish-subscribe messaging method may include determining a schema for structuring raw data published in a publication by a publisher in a publish-subscribe system at a channel node in a network and distributing the schema from the channel node to other channel nodes in the network. The method may include identifying the publication from the publisher at one of the channel nodes and applying the schema to the raw data of the publication at the channel node, transforming the raw data to transformed data. The transformed data may be provided at a subscriber in the publish-subscribe system.
