Considerable progress has been made in representing metabolic and, to a
lesser extent, signalling/regulatory (control) pathways, but there has been little
integration or consolidation of the differing schemes in these areas.
Furthermore, as we move from the static representation of relationships
among bio-objects (genes and DNA regions, RNA, proteins, compounds, subcellular
structures, etc.) to the quantitative or semiquantitative modelling of
their dynamic behavior, additional requirements for more complex representation
appear.
"I'll summarize some of the problems in the representation and display of
static pathway data and dynamic pathway models, discuss some current approaches,
and explore future possibilities.
