1. A method for facilitating interactions between devices, the method comprising: receiving, at a computing device, a first transmission comprising data from a first content provider and a second transmission comprising data from a second content provider; generating, by the computing device, a first message based at least in part on the data from the first content provider, wherein the first message is structured according to: a transport layer defining one or more interaction paradigms for categorizing interactions and defining a plurality of message types, wherein each message type of the plurality of message types includes a set of attributes that comprises at least a message attribute and a transport attribute; a data layer defining one or more data formats, wherein the plurality of message types include payload data formatted according to at least one of the one or more data formats; and a first domain message layer that defines a first set of the plurality of message types used to generate messages between a consumer device and a provider device; generating, by the computing device, a second message based at least in part on the data from the second content provider, wherein the second message is structured according to the transport layer, the data layer, and a second domain message layer defining a second set of the plurality of message types different from the first set of the plurality of message types; and transmitting the first message and the second message to the consumer device configured to parse the payload data in the data layer of the first message in a first contextual manner based on an item type attribute of the first message identifying an item type model of the first domain message layer and to parse the payload data in the data layer of the second message in a second contextual manner based on an item type attribute of the second message identifying an item type model of the second domain message layer, wherein the first domain message layer includes the item type model and a content definition model, wherein the content definition model defines at least one of a field meaning or a field relationship for a field used by the item type model.
