Wayforward of Abstract Information Model
(Mapping Model with Resource Structure)
Group Name: WG5

Meeting Date: 2015-05-18
Agenda Item: TR-0017
Introduction
• In WG5, the abstract information model is developing
for home appliances such as washer, refrigerator as
working of TR-0017.
– In order to avoid cumbersome process between application
developers, the abstract information model provides
common information model.
• In this contribution, we introduce the abstract
information model for home appliances and discuss
wayforward to apply them in the architecture scope.
– The developed model needs to be mapped to resource
structure.

Description
Wayforward (1/3)
• How to map the developed abstract
information model with resource structure?
– Although we can utilize existing resource types
(such as <container>, <contentInstance>), we
introduce the specialized resource types for the
abstract information of home appliances (as
<homeApplianceProfile>)
– Here, the specialization concept of
<homeApplianceProfile> is equivalent to
<mgmtObj>.

The [washer] resource is used to share information regarding the washer. The
[washer] resource is a specialization of the <homeApplianceProfile>resource.
