Wayforward of Abstract Information Model (Mapping Model with Resource Structure) Group Name: WG5 Source: Heedong LG Electronics Meeting Date: Agenda Item: TR-0017

Introduction In WG5, the abstract information model is developing for home appliances such as washer, refrigerator as working of TR – 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. 2

Wayforward (1/3) How to map the developed abstract information model with resource structure? – Although we can utilize existing resource types (such as, ), we introduce the specialized resource types for the abstract information of home appliances (as ) – Here, the specialization concept of is equivalent to. 5

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