Spatial and Temporal Representation

Viewshare is a free tool provided by the Library of Congress that generates interactive maps and timelines with facets for digital collections. The tool presupposes the setup of a user account and data in columnar form that includes location and/or time related data fields.  A few helpful tutorials are available.

  • Data: User supplied.  The example below is from selected metadata from the Cornell HipHop Collection. It included Photographs from Joe Conzo of the early HipHop Music scene and flyers of HipHop venues. 
  • Analysis: The photos and flyers were cataloged in Shared Shelf with spatial and temporal information of the subjects.  Resulting metadata was downloaded in MS Excel format. 
  • Visualization: Spreadsheet was uploaded into Viewshare, ans minimally set up.  Map and timeline tie to uploaded secondary data.

Image Analysis

Ukiyo-e.org is a database and image similarity analysis engine, created by John Resig to aide researchers in the study of Japanese woodblock prints. 

  • Data: Over 213,000 digital copies of prints from 24 institutions, and their cataloging metadata.  Metadata is indexed and searchable.  Details are noted in the about page.  
  • Analysis: Image search uses the TinEye matching engine to determine edges in an uploaded sample and compares with analyzed edges in database, returning probable matches. 
  • Visualization: Tiled images of "hits" for easy comparison, with URL links to their metadata in the source institution's catalog.
