Entries characterize real world entities and define constraints identifying other entities of interest Also, data source entry details on the publishers information - associated to a data vocabulary. Subscribers and Consumers are modeled as independent entities. Subscriptions are created by a subscribers, conforming to a subset of consumer. Structured Information Model, user communities are identified by property and data vocabularies.

Property Constraint Used for matching within the INFOD registry Identifies other entries of interest defining constraints on entry properties. Data Constraint Part of the subscription; evaluated by the publisher Describes an event of interest and the message to be generated by the publisher Dynamic Consumer constraint Part of the subscription; evaluated by the publisher Identifies consumers based on certain characteristics from a set of consumer identified by the INFOD registry.
