Property Vocabulary Instance INFOD Resources Subscribers and Consumers are modeled as independent entities. Subscriptions are created by a subscribers, conforming to a subset of consumer. Publisher Consumer Consumer Subscriber Subscription defines the event of interest at the publisher, the message to be generated in response to an event and helps identify consumers dynamically. INFOD Registry Publisher Entry Subscriber Entry Subscription Consumer Entry Structured Information Model, user communities are identified by property and data vocabularies. Data Source Entry Property Vocabulary Instance Entries characterize real world entities and define constraints identifying other entities of interest Data Vocabulary Property Vocabulary Also, data source entry details on the publishers information - associated to a data vocabulary. Entry Resource – not an entry Creation of resource Reference (EPR) Vocabulary instances characterize entities and constraints are evaluated on instances created. Notification (by INFOD registry) Notification (by Publishers) 9

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

First Responder Use Case Scenario Vocabularies are based on NIEM (National Information Exchange Model) CAP (Common Alerting Protocol) Property Vocabulary Sensor property vocabulary (NIEM) Community user property vocabulary (NIEM) Data Vocabulary Sensor / Alert message vocabulary (NIEM + CAP) Weather information vocabulary (DWML–Digital Weather Markup language) 14

Community User Property Vocabulary Sensor Property Vocabulary Property Vocabulary Predicates Comments Sensor Identification Unique id for sensor Sensor Description Details on the sensor Location Physical location of sensor Contact Information Person to be contacted Associated Organization The owner of the sensor Community User Property Vocabulary Property Vocabulary Predicates Comments Identification Identifier for the Organization Name Name of the Organization Description Text Description Location Physical location information Contact Information Person to me contacted Vocabulary predicates are an abstraction from NIEM (National Information Exchange Model) 15

Data Vocabulary Sensor/Alert Data Vocabulary (NIEM and CAP - Common Alerting Protocol) Data Vocabulary Predicates Comments Activity Description between time period Event Description at a specific time Substance Description of a chemical material Status Actual, Exercise, System, Test Message Type Alert, Update, Cancel, Ack, Error Scope Public, Restricted, Private, Urgency Immediate, Expected, Future, Past Response Type Shelter, Evacuate, Prepare, Execute, Monitor, Assess, None Severity Extreme, Severe, Moderate, Minor Certainty Very likely, Likely, Possible, Unlikely Category Geo, Met, Safety, Security, Rescue, Fire, Health, Env, Transport, Infra, CBRNE, Other Weather Sensor Data Vocabulary ( DWML –Digital Weather Markup Language) Data Vocabulary Predicates Comments Location Weather information at a location Time Information at a specific date & time Temperature Temperature unit as an attribute Wind Speed With units as an attribute Wind Direction As an angular measure Humidity As a relative or specific value 16
