• Freely available data mashups via the
Internet increase access to relevant data
for decision making, which benefits all
libraries and does not require costly
subscriptions to commercial systems.
Nota:
PROS
• Librarians collaboratively create mashup
databases tailored to the needs of collection
managers, resulting in improved access to
relevant data for decision making.
• The distribution of information
professionals, computer programmers, and
IT infrastructure across libraries means that
individual libraries do not bear the burden
of supporting an entire project.
• Professional library organizations have
concentrated expertise in collection
management and discrete subject areas. Their
membership includes new members with novel
insights and skills.
• Continuing to update and host the
data mashup may be problematic.
• Legal permissions to use the data or
other “inputs” in the mashup may be
necessary. Always look for a terms of
use statement on source Web sites or
contact the organization directly
(Lehmberg et al. 2008).
• Continuing availability of data
sources on the Internet is
unpredictable (sources may vanish
without warning or no longer be
updated).
• Variability in APIs’ robustness may
require extensive programming or
tweaks to utilize data in mashup and
thus may be unsustainable in the
long term.
Is one of the pillars of the famous Web 2.0,
the social and collaborative web where
users have something to contribute. A
mashup consists of a web application that
uses resources from more than one source
to create a complete service.
According to the purpose of the mashup, it can be: for
consumers and business or data. The first are the most
frequent, focused on the end user, both through computers
and mobile devices that allow geolocation among other
uses. In the case of business mashups, they are focused on
providing a more corporate solution that the company can
offer its clients or employees. They would be like a
preliminary phase on the way to convert a mashup to
consumers.
