PSI-MI format
• Community standard for Molecular Interactions
• Jointly developed by major data providers: BIND,
CellZome, DIP, GSK, HPRD, Hybrigenics, IntAct, MINT, MIPS, Serono,
U. Bielefeld, U. Bordeaux, U. Cambridge, and others
• Collecting and combining data from different sources
has become easier
• Standardized annotation through PSI-MI ontologies
• Tools from different organizations can be chained, e.g.
IntAct data in Cytoscape.
