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
