Overview
- The Relations Ontology is used in WormBase to describe relations between entities in the database, e.g. genes and GO terms.
- The Relations Ontology was first incorporated into WormBase with the WS267 release.

Parsing Script for ?RO_term Model
- The parsing script to generate the ro_terms.ace file is on tazendra here:
- /home/acedb/kimberly/citace_upload/ro/ontology2ace/ro_obo_to_ro_ace.pl
- Input file:
- Downloaded, manually processed version (see below) of https://raw.githubusercontent.com/oborel/obo-relations/master/ro.obo
- Output file:
- ro_terms.ace
- There are two types of entries in ro.obo
- Term
- Typedef
- At the moment, we include Term and Typedef entries according to the following criteria:
- Include term where id namespace = BFO, RO, lower case text with no namespace: (e.g. results_in_acquisition_of_features_of)
- Skip term where id namespace = CARO, CL, ENVO, GO, ObsoleteClass, PATO
- Note that the terms we skip are used in the OWL representation of the Relations Ontology, but not in the OBO representation
- For the purposes of how the Relations Ontology will initially be used in WormBase, this filtering step should be fine
- Running the script:
- In the /home/acedb/kimberly/citace_upload/ro/ontology2ace directory on tazendra, use the wget command and the above URL to download the ro.obo input file
- Greek characters used in some of the definitions for the RO terms need to be converted to text that ACeDB can render by doing the following (note that we tried to incorporate this as part of the script, but couldn't figure out a way to correctly recognize these characters programtically):
- In one terminal window, open the ro.obo file in a text editor
- In a second terminal window, open the convertGreekVim file in a text editor
- Globally replace the lower case alpha and omega symbols in ro.obo by copying and pasting the appropriate global replacement commands from convertGreekVim, e.g. :%s/α/alpha/g
