is evidence with support from is_evidence_with_support_from evidence_has_supporting_reference has_supporting_reference Note that this relation only links an evidence line to publications actually consulted by the asserting agent to find and interpret evidence items. There may be other publications that describe the same evidence item that the asserting agent did not consult, which would not qualify as supporting references. For example, consider a GO curator's use of sequence data for the rat Vegfa gene in a line of evidence supporting their assertion that the human VEGFA ortholog exhibited the same angiogeneic activity. There may be multiple publications that report this same rat gene sequence, but only the publication that the curator consulted in making this assertion would qualify as a supporting reference for this evidence line. For this resaon, we are not able to create a property chain declaring "has_evidence_item o is_described_by -> has_evidence_item_described_by". . . because this would entail that any publication describing this rat Vegfa gene sequence was a supporting reference for the assertion. Keeping the label has_supporting_reference instead of has_evidence_item_described_by because the later follows the pattern we use for true shortcut relations (i.e. that can be defined using property chains). For reasons outlined in the editor note, this is not such a shortcut relation. has_support_from_source A relation that holds between an evidence line and a citable document from which information supporting the evidence line was obtained (i.e. a "supporting reference"). document evidence line
