System and method for a data protocol layer and the transfer of data objects using the data protocol layer

A method for sharing data objects among applications available on a network, comprising:

• providing a client library coupled between each of the respective applications and a data protocol layer, wherein the client library is associated with a data request module;
• permitting, by the data protocol layer, a flow of data messages among each respective application on the network, at least a portion of the data messages including at least one data object;
• placing a management server in communication with one or more data stores, wherein the management server is associated with a registration module and an event notification module, and wherein the data store contains data objects including, singularly or collectively, the data objects in the data-object sets;
• defining one or more data-types in a data-type definition language, wherein the data-types are shareable among the applications through each of the respective client libraries;
• defining one or more data-object sets in a data-set definition language, wherein the data-object sets are of a given data-type;
• requesting, by the data request module, data objects from the data stores that match a particular data-object set;
• receiving, at the management server, the request from the data request module, parsing the request, retrieving any matching data objects, and causing the return of the any matching data objects to the data request module;
• accepting, at the registration module, subscriptions from subscribing applications;
• and
• capturing, at the event notification module, a data message from one of the applications on the network, comparing the at least one data object in the data message with one or more of the subscriptions, and selectively notifying the subscribing applications in response thereto.
