JCDL 2006 Conference Notes



Day 4 – Metadata in Action

first session

talk 1: frbr – enriching and integrating digital libraries

– proposal – not a standard

publications: group I entities; heart of FRBR model; four-level hierarchical tree
used greenstone;
frbr is currently in corba; moving to soap
automatic extraction – difficult and unreliable
manual entry – expensive
authority – whose frbr to trust?

talk 2: scaffolding the infrastructure of hte computational science digital library

shodor eduction foundation – computational science digital library
ohio supercomputing center
cserd.nsdl.org
evaluate, modify, collection and tag the best of computational maodel based materials;
outlet for peer reviewed publication
using plone, cms and metadata repository – cwis – collection workflow integration system
http://www.shodor.org/cserd
multifaceted search

talk 3: dynamic generation of oai servers

university of americas – mexico
libraries are willing to share digital collections; face obstacles to build oai servers
goal is to have a server generator that automically creates an oai server
voai – for releational dbs
and xoai

talk 4: looking back. looking forward: a metadata standard for lanl's adore

nnssa – los alamos labs

"the library without walls"

adore http://purl.lanl.gov/aDORe/projects/adoreArchive

consolidate metadata schemas from vendors
requirements: granularity, transparency, extensibility, xml based

marcxml – looked to be the best despite its perceived downfalls (which actually turned into strengths)

fears about ridgitity were unfounded; have mapped 85 million records into marcxml; 40 million used by downstream applications

talk 5: learning from artifacts: metadata utilization analysis (texas center for digital knowledge)

research project looking at how catalogers are using marcxml descriptive elements

metadata assumptions

– essential in dig library apps

– will end up with different schemes

– increasing use of machine-generated metadata

– questioning of role of handcrafted metadata

metadata record as artifact

mcdu project

– provide empirical evidence of catalogers' use of marc content designation

– to what extent are metadata catalogers exploiting the complexity of marc?

– dataset 56 million from worldcat (store these records in mysql)

– project website: http://www.mcdu.unt.edu

– ended up with 20 datasets
