Here is a list of suggested symbols for relationships
(I used our ChEBI XML tags)
is_a : open triangle
is_part_of : open diamond
is_tautomer_of : double-headed arrow with
'<greek>tau</greek>'
is_enantiomer_of : double-headed arrow with
'<greek>chi</greek>'; hand symbol (both refer to
"chirality")
is_conjugate_acid_of : box containing '+
H<smallsup>+</smallsup>' (plus proton)
is_conjugate_base_of : box containing '<minus/>
H<smallsup>+</smallsup>' (minus proton)
is_parent_hydride_of : box containing
'H<bond>1</bond>R'
is_functional_parent_of : box containing italic
letter 'f'
is_substituent_group_from : box containing
'<bond>1</bond>R'
Comments welcome

Hi guys,
I've drawn the basic symbols and placed them on my homepage
temporarily.
http://www.ebi.ac.uk/~pmatos/downloads/ontologies/relationship.html
I must say that I have my doubts about "is_tautomer_of" and
"is_enantiomer_of".

One more thing, its not really possible to use Unicode
symbols when we have conjunction like H-R in a box or +H+.
I'm quite happy to use an image rather as the unicode seems
to limit us.
Cheers,

I have attached a page with my variants of ChEBI
relationship symbols. Note there are several variants for some!
