Things

Collections

• This views are organized by collections of things types
  • Filter can be applied to show a subset of collections

Thing instances

Instances can be created, updated, cloned or deleted (See resources edition)

The properties of a thing instance are defined in its type semantic. Some fields are common to every thing type

• Location: spatial location of the thing.
• Proximity area: field used for in-room or proximity location.
• Floor plan: the thing types with the floorplan checked in its semantic will include this field. It allows the user to associate an image to the thing and to calibrate it spatially: to define a parallelogram in the map so the plan could coincide with the thing location. An example could be to associate a floorplan to a shopping center map boundary so we could locate later the different stores present in the mall.

Navigating to a thing instance makes possible to edit its fields using tree editor while fields like location and floor plan require the use of the map.

Apply filters

• It is a good practice to apply filter and/or observers to select the subset of things we would like to work with.
  • Using the map spatial filters can be applied

Unique addressability of things

• AMTech DAP implements it by leveraging on the Semantic Web and focusing on making all thing instances addressable by their URI. See relevant entry in Wikipedia page on IOT.
