WW1 Discovery Project

• Exemplar illustrating principles of the JISC Discovery initiative

• Discovery about advocating ‘open’ and ‘aggregating’

• Make digital content more discoverable by people and machines

• Building WW1 aggregation API and discovery layer

WW1 Discovery: How?

• Aggregate data from existing APIs – IWM and NMM

• Help others with example APIs – BL, MCR Archives, Welsh Voices, LSE

• Formats: SOLR, RSS, OpenSearch, OAI-PMH, CSV

Prototype WW1 API

WW1 Discovery Layer: Info

WW1 Discovery Layer: Geo-data

Some Challenges

• Difficulties merging data– varied content

• Lack of content– images– geo-data

• Content licenses not open• Lack of APIs

Linking Lives

• Linking Lives is a JISC-funded project to create an end-user interface based on Linked Data

• A biographical interface, providing information about individuals that is taken from a variety of sources

• It enables us to place archival descriptions within a much broader context

We can start to say things that go beyond what is known within our own space…and if we use the same URIs we can link data sources much more easily

Vocabularies

Conclusions

• APIs offer useful tools & lightweight approach• WW1: creating APIs for institutions• Locah: Linked Data for over 200 institutions• Linked Data makes use of the Web architecture• Uses HTTP URIs to represent resources• Navigate through things via URIs – Web of Data• Can make APIs more ‘Webby’

Conclusions

• Linked Data opens data up to wide variety of uses

• Can de-reference classes and properties• Need to think more about the end user• Need more tools• Need to collaborate
