Software
Open source and other offerings for community use
OCLC Research offers free software for the benefit of libraries, archives, and museums. The offerings include useful utilities for the development
of library-oriented software and ready-to-use components for library
systems. Most packages are open source, although some are offered under
other licenses. Please be sure to check the license section of the Web
page related to the specific software of interest. Open source
offerings include source code and documentation, as well as the class
files or binaries.
Licensing
Open source
Since 2006 we have issued open source software under the Apache License, Version 2.0.
Many earlier open source offerings were issued under the OCLC Research Public License 2.0 (PDF version;
130K/3pp.). Which license governs a given package is specified on the
overview page for that package as well as in the software itself.
If you have or are interested in open source software licensed under
one of the older licenses and would like to use it under the Apache
license, please contact us – we may be able to update the software to
use the Apache license.
Other licenses
For those few packages not issued under an open source license, the
terms and conditions of use are summarized on the overview page and
available in full before the end of the download process.
Feedback
We are always interested in hearing about your experiences using and
enhancing our software. Please use the contact link below or on the
individual software pages to send us your comments.
Ongoing development
Open source offerings are being further developed as Open Source
Development projects. You may wish to contribute to the development of
this software by becoming a member of one or more of these projects.
The Open Source initiative is described in more detail on the OCLC Research Open Software Development page.
Open Source
| 2PageOAI |
A two-page OAI server in the Python programming
language. Although done as an example of how little code it actually
takes to support OAI-PMH, 2PageOAI implements a useful repository, and
we've successfully validated repositories running this code. |
| DBUtils |
DBUtils includes utilities to support database programming.
It includes packages for ber, Z39.50 and miscellaneous other utilities.
See the DBUtils home page for a more complete description and download options. |
| ERRoL Resolver |
ERRoLs are pointers to metadata, content, and services related to registered OAI
repositories. Anyone can create or use ERRoLs to any metadata record or
web resource related to supported OAI repositories. The open-source
ERRoL distribution presented here contains a J2EE
web application providing URL access to content and services related to
a collection of local and/or distributed OAI repositories.
|
| FRBR Work-Set Algorithm |
OCLC's FRBR Work-Set Algorithm is a step-by-step
instruction for "FRBRizing" bibliographic databases to the "works"
level. See OCLC Research's FRBR Work-Set Algorithm web page for a more complete description of OCLC research associated with this algorithm. |
| Gwen |
Gwen is a database search engine. It provides a boolean query
evaluation package that sits above a database layer and beneath a
Z39.50 server layer. A Gwen-to-Pears interface is included. See the Gwen Open Source home page for a more complete description of the project and download options. |
| OAICat |
OAICat is a Java Servlet to add OAI protocol support to existing data repositories. See the OAICat home page for a more complete description and download options. |
| OAICatMuseum 1.0 |
OAICatMuseum 1.0 is software which allows museums to disclose
descriptions of collection items as well as pointers to digital
surrogates. It can be used to efficiently share digital images with
trusted partners who have requested access to museum content, or with
the networked world at large. See the OAICatMuseum 1.0 home page for a more complete description and download options. |
| OAIHarvester |
OAIHarvester is a Java application to harvest OAI repositories. See the OAIHarvester home page for a more complete description and download options. |
| OAIHarvester2 |
OAIHarvester2 is a Java application providing a combined OAI-PMH v1.1 and v2.0 harvester framework. See the OAIHarvester2 home page for a more complete description and download options. |
| OpenURL 1.0 |
The OpenURL 1.0 protocol is a generalization of the popular
OpenURL 0.1 protocol used to solve the appropriate-copy problem for
scholarly publications. This implementation supports the full range of
abstractions present in the 1.0 specification that takes it far beyond
its 0.1 roots. See also the OpenURL Activities projects page.
|
| Pears |
Pears is a text storage and indexing system. It includes software to build Pears databases. See the Pears home page for a more complete description of Pears databases, the Pears project and the access options. |
| RDF Topicmaps |
RDF
Topicmaps is a proof-of-concept application intended to demonstrate the
benefits of using automatically generated subject indexes to enhance
discovery and navigation in a collection of web pages. Noun phrases are
extracted from web pages and organized into topic relation maps encoded
in RDF. A user interface for browsing and searching the topicmaps is also included in the package. |
| Scorpion |
Scorpion implements a system for automatically classifying
Web-accessible text documents. Scorpion is intended for use by
investigators who have a machine-readable subject classification scheme
or thesaurus and wish to incorporate it into an automatic
classification system. |
| SRW/U |
SRW/U Open Source software
implements both the SRW Web Service and the SRU REST model interface to
databases. It includes interfaces that support DSpace's Lucene
implementation and OCLC's Pears and Newton databases. |
| Webutils |
Webutils includes utilities for harvesting the web and extracting metadata from the harvested html pages. See the Webutils home page for a more complete description and download options. |
| XSLTProc |
XSLTProc is a tool for distributing the management and use of
arbitrary XSL stylesheets. The open-source Java Servlet provided here
demonstrates an application of the model. |
Other software
| COBOAT |
COBOAT is a metadata extractor tool developed by
Cognitive Applications Ltd., and extended as part of the Museum Data
Exchange project to allow export of CDWA Lite XML from cultural
heritage institutions' databases. |
