Life Science Identifier (LSID):

LSIDs are persistent, location-independent,resource identifiers for uniquely naming biologically significant resources including species names, concepts, occurrences, genes or proteins, or data objects that encode information about them. To put it simply, LSIDs are a way to identify and locate pieces of biological information on the web.
