Setting metadata properties dynamically

[aembee]

I'm working on a fusion scenario where I am setting the metadata properties to my custom component dynamically. Below is the high level structure of a single collection of JSON data. 

 I need to get properties from myContentAttributes collection and create a structure like this:

"mycustomComponent": {

"item0": {

       "propName": "propA",

       "propValue": "valA"

},

"item1": {

       "propName": "propB",

       "propValue": "valB"

},

"item2": {

     "propName": "propC",

     "propValue": "valC"

},

.......

}

I am able to get the property names by iterating through keys of myContentAttributes but not sure how to get the values of corresponding properties. 
Thank you in advance!

hi @aembee 

to get the value of the respective key, get( myContentAttributes ; {{iterator value}} )
