LinkDB is a database of links, each of which is represented as a binary relation in the form of:
dbname1:identifier1 --> dbname2:identifier2
LinkDB contains all cross-reference links, original and reverse links, extracted from all the databases in DBGET. Furthermore, LinkDB provides additional links, equivalent links, representing the relationship between same objects in different databases. Thus, the links in LinkDB are of the following three types: original, reverse and equivalent
It is really useful to map all the Ids from one database into another.
