Discussions

    * Publishers and Data Sources define property vocabulary instances,
      consumers and subscribers define constraints on publishers and
      data sources. In a use case as in sensor network, a sensor could
      either  be a publisher or a data source, meaning certain sensors
      can be independent; and a few of them clustered to be a part of
      the single publisher and have property vocabulary instances
      associated with data source entry's. When defining a constraint
      the consumer needs to know if the sensor property vocabulary
      instances are associated to a publisher or a data source, and
      define publisher constraints or data source constraints
      respectively. In the hierarchical model, the data sources can
      inherent some properties from the publisher or not. It was
      concluded to keep it simple, with the use case implementation
      bound to one kind of relationship, for example in the above use
      case, register all sensors as data sources.
    * The discussion of INFOD use case was rescheduled for the next
      call. Dieter discussed on sending messages to consumers with the
      help of service providers of GPS, messaging services, where the
      message received would be based on the event and the properties of
      the consumer.

The next conference call will be on Monday, March 24th @  4 pm EDT.

Raghul
