The OSC Non-RT RIC provides a high performing, fully scalable end-to-end solution for handling
-PM Mesurements. A PM report (containing aggregated PM measurements over a time interval) is
+PM Measurements. A PM report (containing aggregated PM measurements over a time interval) is
an XML file. The format is defined by 3GPP (TS 32.432 and 3GPP TS 32.435).
The files are collected from the RAN and stored. An rApp can subscribe for chosen measurement types from
measured resources in the network.
The picture illustrates the components involved.
* The PM Data File Collector fetches the XML files from the RAN.
-* The PM Data Converter converts these to a Json format. The structure and the contents
+* The PM File Converter converts these to a Json format. The structure and the contents
is the same as the XML format.
* The PM Producer handles filtering and distribution of PM data to subscribers. These subscribers can be rApps.
-* The Influx Logger stores selected PM mesurements into a time series database.
-* HTTPS-SERVER is for testing and implements functionality to simulate file transfer from thye RAN nodes.

The third party products used are:
* Minio object storage, for storing of files.
* Kafka for transferring of data (not the full PM reports, though)

Data Flow
2. The VES event is put on a Kafka topic and picked up by the Data File Collector.
3. A PM report file is fetched from the RAN node by a file transfer protocol. Which protocol to use is defined in the VES event.
4. The collected file is stored
-5. A File collected object is put on a Kafka topic and is picked up by the PM Data Converter.
+5. A File collected object is put on a Kafka topic and is picked up by the PM File Converter.
6. The file data is read from the file store.
-7. A PM report in json format is stored.
+7. A PM report in json format is stored (compressed with gzip).
8. A message (a Json object) indicating that a new PM report (in Json format) is available is put on a Kafka topic and is picked up by the PM Data Producer.
9. The PM data producer reads the Json file
10. The subscribed PM data is sent to the PM data consumers (over Kafka). An rApp may be a PM data consumer.
PM Data Subscription
********************
PM measurement data is subscribed by creating an Information Job using the Information Coordination Service (ICS).
-This a subscription broker and is part of what is called Data Managament an Exposure (DME) in O-RAN.

The ICS makes sure that all data producers gets its data subscriptions (jobs).
In the picture below, an rApp and the Influx Logger are consumers of PM data.

The PM Data Influx logger will create a PM data subscription based on a configuration file. An rApp can create
-PM data subscpition. The PM Data producer will deliver received PM measurements according to the subscriptions.

The PM Data file collector will fetch all PM measurement files. The PM Data Converted will convert all fetched xml files
to json. So these does not use any subscriptions.
PM Subscriber design time dependencies
**************************************
-An rApp uses the ICS API, which is avaiable in `Non-RT RIC - Information Coordinator Service (Documentation site) <https://docs.o-ran-sc.org/projects/o-ran-sc-nonrtric-plt-informationcoordinatorservice/en/latest/>`_.

+The schema for the PM Me

This schema defines parameters used in the subscription (info job) and defines which measurements to subscribe for and on which
kafka topic the information shall be delivered to.
-An application retrieving logged PM data from the Influx database needs to know how the data is stored. That is
