... similar to the one last year
... two sessions
... one in the spatial group on Tuesday
... and another on Thursday
... we talked about TD
... little discussion by the Spatial group side
... possible use of SSN
... interesting in some proposal to define property for SSN
ontology
... some sort of device description
... if you have a sensor within SSN

... measurement description
... generated based on TD
... they're planning to send that proposal to the Device
group
... but possibly to TD as well
... and Thursday

seba: good cooperation for
vocabulary

... also they're using WebSocket-based architecture
... I'd like to use TD for the OCF REST interface
... signal themselves have some type
... they use programing language type
... think all promising
... really would support VSS
kaz: VSS has tree structure
... and each terminal node has concrete data with some data type, e.g., Int16 (as well as max, min, enum, unit, etc.)
-> VSS Tree
michael: within YAML there is also Max, Min, etc.
victor: Michael, resources on the OCF side?
michael: we defined all the
branches as data collection
... cabin has doors, etc.
... and the door has property of open/close
... some kind of query for the information
... I can share all the information about mapping
... different kinds of TD
seba: also there were some small
meetups as well
... demo plugfest on Wednesday
... discussions with the audience
... plugfest content was what we already had for the Beijing
meeting
... and we generated banner posters to show what the building
blocks were

... how to work with small micro controllers, etc.
... we had another table on Scripting API as well
... also Protocol binding
