VuFind is developed to ensure the users to search and browse through
all of your library's resources by replacing the traditional OPAC to
include:
· Catalog Records
· Locally Cached Journals
· Digital Library Items
· Institutional Repository
· Institutional Bibliography
Greenstone is for building and distributng digital library collection
and organizing that information. Integrating GSDL on VuFind is not hard
as both software uses OAI-PMH protocol for metadata harvesting. Moreover
there is already DSpace integrated on VuFind and with its reference,
oai settings and other properties file are created as both GSDL and
DSpace use Dublic Core Metadata Set.
OAI must be enabled on the Greenstone repository first:
You can modify file of Greenstone to enable and configure OAI-PMH on file:
$GSDL_HOME/etc/oai.cfg
Then you may proceed to import the OAI feed into VuFind:
1. Modify $VUFIND_HOME/harvest/oai.ini as per oai.ini below
2. Create and modify $VUFIND_HOME/import/gsdl.properties as per Greenstone properties below
3. Create & modify $VUFIND_HOME/import/xsl/gsdl.xsl as per gsdl.xsl below
4. cd $VUFIND_HOME/harvest
5. php harvest_oai.php
6. sh batch-import-xsl.sh ./Greenstone ../import/gsdl.properties
7. ../vufind.sh restart
oai.ini

gsdl.properties
; XSLT Import Settings for GSDL [General] ; REQUIRED: Name of XSLT file to apply. Path is relative to the import/xsl directory ; of the VuFind installation. xslt = gsdl.xsl ; OPTIONAL: PHP function(s) to register for use within XSLT file. You may repeat ; this line to register multiple PHP functions. ;php_function[] = str_replace ; OPTIONAL: PHP class filled with public static functions for use by the XSLT file. ; The class name must match the filename, and the file must exist in the import/xsl ; directory of the VuFind installation. You may repeat this line to load multiple ; custom classes. custom_class[] = VuFind ; XSLT parameters -- any key/value pairs set here will be passed as parameters to ; the XSLT file, allowing local values to be set without modifying XSLT code.
