7. The Linked Logainm Project
• Concept:
• to republish the logainm.ie dataset as Linked Open Data
• allowing it to be reused by computer programmers, app
developers, heritage professionals and more..
• Project ran October 2012 – September 2013
• Project outputs
• the Linked Logainm dataset
• the Location LODer demonstrator website
• project report and Using Linked Logainm Guidelines document.

•
The authority list of Irish place
names, validated by the Place
Names Branch of DAHG
Place names, translations,
variants, types, hierarchical
structure
Unique source of Irish
language place names – not
available in other LODatasets

10. The Linked Data Concept
• A method of publishing structured data on the Web,
allowing it to be connected and enriched, and facilitating
linking between related resources.
• Linked Data standards such as RDF (Resource
Description Frameowork) allows semantic definitions to
be applied to information, using statements called
‘triples’ in the form subject, predicate, object.
DRI Presentation

11. A key principle of Linked Data is that HTTP URIs are
used to name the semantic elements of the dataset

15. The Longfield Maps & Linked Logainm URIs
1,570 maps catalogued in MarcXML
- <marc:datafield tag="650" ind1="" ind2="">
<marc:subfield code="a">Land
tenure</marc:subfield>
<marc:subfield code="z">Ireland</marc:subfield>
<marc:subfield code="z">Rathdown
(Barony)</marc:subfield>
</marc:datafield>
- <marc:datafield tag="650" ind1="" ind2="">
<marc:subfield code="a">Land use
surveys</marc:subfield>
</marc:datafield>

16. URIs & the NLI Catalogue
•
•
•
Application of authoritative place name data to catalogue
records
Single URI for the place name:
Allows users to search in either Irish or English
Redirects searches for variant place names – “Ceara” or
“Cera” will redirect to “Carra”
Redirects within hierarchy – search for townland not found in
the catalogue could redirect to maps for the related barony
Potential to draw in contextual information from other
datasets, eg. current population, meteorological data etc
