> +Question:+
> REST API - Past values of an entity
> +Description:+
> What I have
> Docker Containers:
> Orion CB
> MongoDB
> What I do
> I use the REST API (NGSIv2) so I:
> Create an entity (using POST)
> Update the values from this entity (using PUT)
> Get the value from the entity (using other app: GET)
> My question
> Is there any way (inherent to ORION) to have the full history of values of this entity? Something like a queue of messages, or so, being them the values of this entity.
> If not, which mechanism should I use (inherent to ORION again) to be able to build it in my second app?
> I guess I expect to have a subscription mode or whatever so I get a notification of a new value (public/subs model?) still using the REST API in my second app, not needing it to have hard-coded when a new value of the entity will be available at ORION, since this may be unknown even for me.
