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!
