Newspaper Models Acceptance Testing

(For the sake of brevity, not all classes and metadata fields appear in the console examples.)

Classes ✅

There should be 6 classes:

• NewspaperTitle (PCDM Object)
• NewspaperContainer (PCDM Object)
• NewspaperIssue (PCDM Object)
• NewspaperPage (PCDM FileSet)

Overview

For each of these JSON word-coordinate file formats of the same OCR word-coordinate data, representing a single newspaper page:

1. Open-ONI (58.9 kB)
2. IIIF Annotation List (826.4 kB)

I ran a test in the Rails console, benchmarking the time needed to:

1. load the source file into memory
2. parse as JSON
3. find nodes matching a search term ("October")

bpl-mapportal development guide

The goal of this project is to update the major dependencies for an existing Rails application currently in production.

This application is a digital library interface that provides access to historical maps from the Norman B. Leventhal Map & Education Center at the Boston Public Library. The application allows users to search the collection, view image content, download high-resolution files, sign up for an account, and create lists of favorite items, as well as other features.

URL: https://collections.leventhalmap.org/

Code: https://github.com/boston-library/bpl-mapportal/tree/develop/src/portal (private repo)
