It is. You can iterate over all the objects in the GH_Document. That will tell you which top-level objects are present. It will not include input and output parameters of components. If you want to include those as well, then you'll need to iterate over all attributes in the GH_Document.

Relationships are a bit harder to get. You could either iterate over all the attributes, find all parameters and look at the Sources and Recipients lists. You could also use the GH_Document.CreateConnectivityDiagram method to create a data structure which contains all the forwards and backwards links that are present in a GH_Document.

The Script component will have a GrasshopperDocument field you can use. Or you can use Component.OnPingDocument() (or owner.OnPingDocument() if you're running an older version of GH)
