    Can we use notification event to update product inventory information...for example product attribute value change event for updating the product inventory. I am raising this question because my understanding is notification event can be published post operation which means  product inventory patch operation will result an event of product attribute value change and if my understanding is correct then what term we will use for that event which will be consumed by product inventory SOR to update

    The notifications are results of operation i.e. first change is applied and after that notification is send. TMF defines only output notifications which external clients might be interested in. The modification of resources is through REST API which your system suppose to expose to meet TMF compatibility criteria. 
    If you want to use event based API for similar operation I think you can. In that case the payloads/names are totally up to you. This should be considered as system internal implementation which exists together with standardised one (TMF).

    Thanks Sebastian .... Does it mean we do not have any guideline for event based API?

    The BOS Catalyst (Nice 2019) contributed AP-1340 which describes various issues and methods for keeping Catalogs and Inventories synchronized in a multi-vendor ODA Canvas.

    Tarique - Going back to your original question, the Product Inventory itself (as an exemplar for any persistent storage for entities) would updated by a synchronous POST or PATCH operation invocation in the TMF637 API. As you correctly stated, a side-effect of this creation or update will be raising the corresponding events.

    So now you need to consider - who is updating the inventory and why. The ODA use cases for commerce (UC003 and UC004) show examples of the order capture and then management making updates to the inventory during order processing. It's extremely unlikely that you would expose inventory updates to an external consumer.

    Hope it helps
