+## Expansions do not interact
+
+Expansion queries are applied to the input ontology, not to the output of any other expansions. So, expansions do not
+interact with one another. If you wish to implement interactions between expansions the command could be changed, e.g.:
+
+```
+robot expand -i myont.owl --expand-term A expand --expand-term B -o my-expanded.owl
+```
+
+It is possible that other expansion approaches that support interaction could be added to this command in the future,
+such as an RDF rule engine.
