The OpenURL
framework is the result of research on open and
context-sensitive
reference linking in the web-based scholarly information
environment,
conducted by Herbert Van de Sompel in 1999-2000 while at Ghent
University
and at the Research Library of the Los Alamos Laboratory. A series
of
experiments
showed how electronic information resources could delegate the
generation
of reference links to third parties, thus allowing for the
establishment
of an information environment that is interlinked according to the
third
parties' preferences. The proposed solution builds on the
introduction
of a linking server operated by those third parties, as well as on
the
adoption of an interoperability specification connecting
information resources
and linking servers.
Van de Sompel, Hochstenbach and Beit-Arie published a draft
version of
such interoperability specification as the OpenURL,
early 2000. As part of the experiments, a prototype linking server
was
designed and developed in a collaboration between Hochstenbach and
Van
de Sompel. Later, it was acquired by Ex
Libris, which now successfully markets it as the SFX
server. Soon after the publication of the OpenURL draft, leading
information
providers started adopting the specification. A further
experiment illustrated the ease by which the OpenURL framework
and
the DOI-based CrossRef
linking
approach could be integrated and how, through this integration,
they mutually
enforced each other.
As a result, NISO started the
standardization
of OpenURL in March of 2001. By that time, Van de Sompel and
Beit-Arie
had generalized the OpenURL ideas to become applicable beyond the
scholarly
information environment in the Bison-Futé
model. That model lies at the basis of the work of the NISO
AX committee, of which Herbert Van de Sompel is an active
member.
The introduction of open linking capabilities is generally
considered
to be one of the most important recent innovations in the
scholarly information
environment. The OpenURL Framework is now ANSI/NISO Z39.88-2004.
At the Research Library of the Los Alamos National Laboratory,
the OpenURL specification and the LinkSeeker implementation of the SFX
server
are used to dynamically interlink internal and external
information resources,
in a way that meets the preferences of its cross-organizational
customer
base. The generalized Bison-Futé concepts will play a
crucial role
in the communication with
"document-relationship-servers" that
the Prototyping team is exploring.
