The GO is changing the identifiers used in Reactome cross-references (xrefs).
Currently we create xrefs IDs of the form "Reactome:REACT_XXXXX". These will be changed to canonical Reactome xrefs of the form Reactome:R-HSA-YYYYYY. An additional change is that we will only include xrefs to the human reaction, and will not include xrefs propagated to other species (let us know if you need these, and we can provide a method for obtaining these from Reactome).
