Hi, I'm having trouble understanding the utility of object

better? Can you reference meta data (object attributes)? Can you use
these
references as metadata?
You can't reference metadata, but you can use references as metadata,
which is one advantage over links. I use this to indicate dependencies
between datasets, by adding reference attributes. You can also store
references in data sets, e.g. have an array of references.
