What is Open Source
Software?


Open source software is software
distributed in source under licenses
guaranteeing anybody rights to freely use,
modify, and redistribute the code.



The Open Source Initiative (OSI) is a non
-
profit corporation that acts as a standards
body for open source. To use the Open
Source Initiative Approved License
trademark the software must meet 10
criteria, including Free Redistribution and
the Source Code.

Why Open Source?


Company Models:


Manufacturing Model (Sale Value)

versus


Service Model (Use Value)

Software Development:
Manufacturing Model


Software is developed by a company
for sale


Price of the software is based upon
the development costs


Can lead to little incentive to provide
service and updates


Software is only of value as far as it
can be sold

Software Development:

Service Model


Software is developed for use


Software is free or low cost


Service is available for a fee

Software Development:

Some Facts


95% of code developed is for in
-
house use and therefore has no sale
value


75% of a developer’s time is
consumed by maintaining and
debugging existing code


Once expended, development costs
are sunk costs

Open Source Integrated Library
Systems and Public Access
Catalogs


Almost every open source product
originated because when conducting
marketplace reviews, libraries found
that systems that met their needs
were too expensive or lacked
desired features

Koha


Koha.org


A New Zealand consortium
commissioned a company to develop a
Web
-
based system for use in its libraries


They determined that the software should
be open source so that other libraries
could use it and make further
improvements.


Koha is currently in use in several library
systems in the several countries

eXtensible Catalog


Extensiblecatalog.info


Currently being developed by the
University of Rochester with a grant
from the Andrew W. Mellon
Foundation.

What can libraries do with
open source solutions?
