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 componentsCustom 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
