INFOD Resources
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.

12. Constraints
Constraints are for expressing entities and data of interest.
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
Identifies consumers based on certain characteristics from a set of consumer identified by the INFOD registry. 12
