Looking for advice on node level metadata

[Adam von Nieda]

   Hi folks,

   I’m wanting to make available to pipelines detailed metadata about what resides on specific nodes, in terms of applications, path names etc. Some nodes may have multiple applications on them, so I need to be able to loop through the application metadata on a node. If I were to visualize it in JSON, it would look something like below. At first I thought maybe node level environmental variables would be the way to go, but that makes it kind of ugly for nodes with multiple apps. I’ve kind of settled on using readJSON I’n my pipelines to get the metadata. Is there a better way to do this? 

   Thanks!
