This modified work sample employs a responsive design using only HTML & CSS, using Flexible Box Layout (Flexbox) instead of external libraries.

Fedora Commons Ingest Tool

Fedora Commons is an open source repository for digital collections. This tool automates the ingest of digitized items and metadata into a Fedora Commons 4 instance.

All object relationships conform to the Portland Common Data Model.

All PHP code uses the PSR-2 (Coding Style) and PSR-4 (Autoloading) standards. This library was released under the GPLv3 License.

The library is installed via Composer:
$ composer require unhplace/fedora-ingest

Usage

use UNHPlace\FedoraIngest\FedoraCollection;

// Create a new collection with a named slug
$col = FedoraCollection('col-1');

// Set the local path for binaries
$col->setBinaryPath('data');

// CSV source
$col->ingestCsv('csv/metadata.csv');

// FGDC XML source
$col->ingestFgdcXml('xml/*.xml');

// Print the Linked Data URIf
echo $col->getUri();

CSV keys are Dublin Core metadata elements, e.g., dcterms:identifier, dcterms:title, dcterms:coverage, etc.

The project was funded by the Institute of Museum and Library Services, National Leadership Grants for Libraries Program.

Drupal & Solr

The UNH Library Digital Colllections (2017) used the Solr search server to index their scanned documents, full text, and metadata. Drupal has a community-supported module to provide search facets using Solr fields.

This project required developing a Solr schema and appropriately weighting index columns to support keyword search.

A custom Drupal module provided a connection between Fedora Commons and the Drupal theme.
