+# Command to split annotations using comma as a separator. If the annotation uses a different sep, please update the Python script.
+# The annotations that will be split are population synonym (AfPO:0000450) and family (AfPO:0000565).
+# 1. Need to convert to RDF/XML to be able to load the ontology using rdflib. rdflib can load OFN, but it requires the use of the plugin
+# rdflib-owl which needs to be installed, and it's not available in the ODK. 
+# 2. Run Python script which queries each annotation entry and splits it using the separator into N annotations.
+# The N new annotations are added to the annotation.owl graph and the combined annotation is deleted and saved in afpo-edit-annotation.owl
+# The two graphs could be merged into one, but this gives a chance to review the changes.
+# 3. Merge the two owl files and save the output as afpo-edit.ofn after converting as OFN.
+# 4. Remove intermediary files
