pdg.Graph has all of the same methods as pdg.WorkItem for adding/setting attributes. For example, in a Python Script. you can use the following to create a global string attribute named "example" that appears in the MMB menu on the TOP Network itself:

If you want the global attribute to be deleted when the work item that created it is deleted, then you should create the attribute using the Graph (Bound) type instead of the Graph (Global) type as described here: https://www.sidefx.com/docs/houdini/nodes/top/attributecreate.html#stringscope [www.sidefx.com]

Truly global attrbutes are saved as part of the graph if the Save Graph Attributes to .hip toggle is enabled on the network manager node. The purpose of unbound global attributes is provide a persistent place that work items can score key/value data, for example if you wanted to output file versions between multiple consecutive cooks of the same TOP network.

Global attributes are supposed to appear in the MMB window on the TOP Network manager itself, but it looks like that was broken with the introduction of the new MMB info window across all contexts in Houdini. Please log a bug for that.
