Hello
I and my group have been working on Om2m for few months and we got to this topology

MN-CSE <---OM2M registeration --> IN-CSE<---> AE1

AE2 --------POST Request (register)----> MN-CSE
-------POST( add container )------->
---------------POST(Data)-------------->

our Sequence as the following:
1- IN-CSE runs
2- MN-CSE runs
3- MN-CSE register in IN-CSE
4- AE2 runs, register into the MN-CSE and adds a container for data
5- Data start flowing from AE to MN-CSE via HTTP (POST) requests
-----------------------------------------------------------Up to here we believe we are good
the following we have issue with
6- push (POST) the Data from MN-CSE to IN-CSE
7- push (POST) the data from IN-CSE to a second AE1 via HTTP requests
However, our issue is that We do not know how we will move the Data from MN-CSE container to IN-CSE,

we can navigate through the webpage interface to verify that MN-CSE contains the Data which it dose.

Hello,

In my opinion you could use the subscription / notification mechanism provided by oneM2M (and implemented in OM2M). That means your AE1 should suscribe to the DATA container of AE2, then MN-CSE will send notifications to the IN-CSE that will redirect it to AE1 when a new content is pushed. So AE1 can process the data if needed and eventually store it in the IN-CSE.
This requires your AE1 to have a server part that will receive notifications. You have some hints for the subscriptions in tis tuto: https://wiki.eclipse.org/OM2M/one/REST_API#Subscribe_to_MY_SENSOR_data

Hope this helps,
Guillaume

Hello.
Using this tutorial, https://wiki.eclipse.org/OM2M/one/REST_API#Subscribe_to_MY_SENSOR_data, what payload should I use to subscribe MN-CSE data to IN -CSE data?

thanks
