UC San Diego Library: Where we are with Linked Data Arwen Hutt

What we’ve done so far: RDF triplestore Designed and implemented a local data model and ontology (using MODS/METS for inspiration and MADS for authorities) and converted our legacy data Converted strings to things (sort of) - names, titles, subjects are all represented by (local) URI’s BIBFRAME monitoring group – lots of LD discussion!

What we’re working on now: Contributing to the community development of Fedora 4 and Hydra Revised, tiered, community data model Portland Common Data Model DPLA Metadata Application Profile UCSD needed Classes and Predicates When possible, using properties from community schemas (DC, DPLA, Schema.org, etc.) Simplify SKOS/DC instead of MADS Improved RDF encoding Simplify some metadata New approach to rights and access metadata, including using existing URI’s (Creative Commons, Europeana) instead of text

Snippet of new data model spreadsheet, highlight the tiers and then the other uri’s (add a bibframe one?)

We’re also investigating: Adding URI’s to MARC records Enhancing identity management Connecting the dots, entity resolution (“strings” to things) and reconciliation (things to things) Using LD for improved user experience - search expansion, enhanced browse, etc.
