Dataset Work

  • I’m continuing in my work from Sunday and attempting to create RDF/XML using Joshua’s finalObject.csv file from last semester
  • His script for generating JSON-LD (2015-16_JDull/Code/objectsCode/objectJSONLD.py) could be helpful for format conversion, though http://rdf-translator.appspot.com/ could also work, depending on how accurate it is.

Tableau

  • I started a Tableau visualization of provenance sources:

Notes From Farris

  • Hoping to append current collection pages with linked data.
  • Create sample records for each entity type (Constituent, Object, events, etc). Yale Center for British Art as model.
  • Confirm Skype date w/Cristina
  • Do not resolve against base URI (IDs rather than set URLs), as these URLs are not known.
  • Tableau – great, but try to include purchase dates of objects, plus biographical details about constituents, possibly linking to Wikidata, etc. The Wikidata coordinate location property (https://www.wikidata.org/wiki/Property:P625) if nothing else
  • WorldCat identities – bibliographic source?
