MyResearch Portal, Andrew Nagy

MyResearch Portal: An XML based Catalog-Independent OPAC
Andrew Nagy
Villanova University

completely ILS agnostic portal for research activities
– catalog, DBSs, digital library
– single search interface

most resources are in XML
– digital library: METS
– Metalib XServer: XML
– catalog: MARCXML
– web site: XHTML

data store advantages in XML
– native XML stores easily, easily entered
– no need for RDBMS

eXist
– open source XML dbs
– full-text searching available
– platform independent: java backend; API through REST or SOAP
– inherent directory structure
– LDAP support
– however, not really meant for a library search type of system

Berkeley DB XML
– proven
– wide range of platforms
– good performance
– commercial backing, decent help
– no full text extenstions, no inherent directories

commercial solutions? – too expensive, more complex

implementation challenges
– eXist innappropriate
– DB XML capable, but slow, even with some reconfigurationm
– MARCXML very complex, lots of unhelpful data, field names actually in attributes

moving MARC field number into tag improved response times considerably

technologies don’t tend to understand the complexity of library data
queries not well optimized, if at all
– needed to develop very basic query processing

SOLR/Lucene looks like the answer
