Motivation: Links between biological objects are frequently used by re
searchers in biology. However; many of the links found in public datab
ases are insufficiently documented and difficult to retrieve. Virgil i
ntroduces the idea of a rich link, i.e. the link itself and the relate
d pieces of information. Virgil was developed to collect, manage and d
istribute such links. Results: At the moment, Virgil is a prototype da
tabase that contains rich links between GDB genes and Genbank sequence
s. The Virgil data model is rich enough to describe comprehensively a
link between two biological objects. Two different means to access the
information were developed: a schema-driven Web interface and a CORBA
server.
