What is a
Digital Library ?
• A DL is the combination of “content and services”
• A DL is an “entity” providing the functionality to mediate
b t
between
information
i f
ti objects
bj t and
d information
i f
ti users iin th
the
context of distributed collections of information objects. This
(external)
(e
e a ) functionality
u c o a y includes
c udes access, pub
publish,
s , de
delivery,
e y,
preservation, personalization, etc.
• A Digital Library is a “tool” at the centre of intellectual activity
having no logical, conceptual, physical, temporal, or personal
borders or barriers on information
• A Digital Library is an “institution”
institution in charge of providing at least
the functionality of a traditional library in the context of
distributed and networked collections of information objects

Reference Model for DLS
Formalize a conceptual framework for Digital Library systems
 to serve as a yardstick of quality and richness
 to specify features and properties of generic DLMS
 to clarify relationships among
 digital libraries, digital repositories, digital archives,
 search engines, information infrastructures,
 knowledge commons
