Chapter -- Accessing data

Accessing data

• web interface (downloads, citations, Zotero)
• APIs:
  • search
  • newspaper article
  • work
  • newspaper title
  • institutional contributors
  • people & orgs (OAI-PMH, SRU)
  • archived websites (Memento, CDX)
• undocumented internal APIs and embedded metadata
  • lists of journal issues (example)
  • digitised work metadata (example)
  • positional information linking OCRd text to page images (example)
• downloadable datasets (examples)
• Trove data in other systems – eg use of Trove identifiers in Wikidata

Data types in depth

• Detailed examination of each data/format type examining:
  • an overview of the data corpus – what's available and what's missing, how the corpus has changed, implications for research use (Moved to #28 )
  • what metadata is available and how it is structured
  • how to access to full text/images
  • limits to access (eg image resolution, copyright)
  • assembling datasets for research

[wragge]

I think I'll try to include some details about accessing images from other organisations that are aggregated into Trove, where that's fairly straightforward: eg NAA RecordSearch.

• There's already a notebook in the GW that shows how to get from a handle in Trove to IIIF images in SLV
• Should be able to do the same with SLQ -- handles go to a page with an IE identifier. There's an internal API that retrieves more info using the IE identifier. The JSON response includes IIIF links.

  "description": "Clement Lindley Wragge, meteorologist, was born 18 September 1852 at Stourbridge, Worcestershire, England. Orphaned in early childhood, Wragge was educated at Uttoxeter Grammar School in Staffordshire and articled to a London solicitor. In 1876 he joined the South Australian surveyor-general's department. Wragge studied meteorology and in 1878 returned to Britain where he established weather observation stations. He founded similar stations in South Australia and founded the Meteorological Society of Australasia in 1886. In January 1887 he was appointed meteorological observer in the Queensland post and telegraph department. Wragge expanded the observation network, issued forecasts, pioneered research into tropical revolving storms in the south-west Pacific, lectured extensively and built an observatory at his Taringa home.\r\nAfter advocating the creation of a national weather bureau he was bitterly disappointed in 1907 when H.A. Hunt was appointed head of the Commonwealth Meteorological Bureau. Wragge moved to Auckland, New Zealand, where he built an observatory. He revisited Queensland in 1913 but failed to win support for his proposed tropical cyclone research centre. He died following a stroke at Birkenhead, New Zealand on 10 December 1922.
