Semantic Name Authority Repository Cymru

Linked database of authority records and related data for people and places in Welsh archives

131,228 Items.

 Introduction

The Semantic Name Authority Repository Cymru (SNARC) was established in order to provide a central hub for name authority records relating to Wales and in the Welsh language. The dataset includes data about peoples with National Library of Wales authority records, Places with standardized names in English and Welsh, and all the data needed to describe these things, from languages and occupations to historic buildings, administrative areas, cities and countries. Based on Wikidata, but using a simplified and customized ontology, the data is presented as Linked Open Data and this makes it easier for us to define relationships between entities in our collections. All the data is bilingual and available on an Open Licence. The dataset can be explored using the search box on this page, the links below or using the API or Query Service. Our goal is to grow the dataset using data from Welsh cultural organizations, connecting our heritage in one central hub. It will also act as an important bridge between 3rd party linked open data from Wikidata and other sources, and data curated by GLAM professionals around the world.
