Dr. Jane Gray, IQDA Changing life patterns in Ireland, 1900s to present Life Stories "My mother used to make a ball and we used to play ball, she used to make a hurl out of a bit of a board and make the handle a bit thin and you could catch it, no shape or make it only a bit of a board. And she used to make a ball out of a soft set of turf and put an old sock around it"

REPOSITORY STRUCTURE

Open source components Custom code to join them together

OAIS model

Using Hydra – ruby on rails Obvious to use Blacklight Therefore use SOLR Objects injested into Fedora Commons Use the Solrizer gem to create the Solr index Search setup

Object metadata all CC0 Search will return metadata on all records Authorization system will restrict access to the objects Multi-lingual data (English and Irish at the moment) Indices for each language Can search across specific or all Search setup

DATA PRESERVATION

Multi-site repository Dublin and Maynooth (~25km separation) Asynchronous replication Ability to catch errors on the fly Segregated storage Master copies with surrogates for public access Preservation strategy

Using CEPH as the underlying storage system Provides Posix, S3 and Block access Using S3 – potential to move to commercial cloud Tiered storage and multi-site features Erasure coding to reduce raw storage needs CEPH features

Groups of objects bundled using bagit format Checksums built into the format for error detection Useful for bulk transport of objects Potential integration with DARIAH storage testbed Data representation

USER ACCESS

Primarily through the blacklight search interface Other routes Curated collections and virtual galleries Georeferenced data – mapping Temporal data – timelines User definied collections DOI references in papers User Access
