Imagine you have digitized many books from your collections and made them available via Omeka S in a IIIF-compliant viewer. Naturally you would also like your users to search the full text contents of these books, as that is something they cannot do with a physical copy. This blog will describe the steps to make this possible in Omeka S by using a module that implements the IIIF Content Search API.

Prerequisites

Make sure you have taken the following actions before you start:

• Working Omeka S instance with IIIF modules enabled (see our previous post)
• Digitized book... read more

1. Install and switch to ‘vips’ from ImageMagick for faster image processing in Omeka S.

3. Prefer JPEG quality 80 as the source image type for the best balance of performance, disk space usage, and viewing quality.

Avoid JPEG 2000 and uncompressed TIFF due to performance issues and high disk space consumption.

Introduction

When integrating IIIF capabilities into our Omeka S environment, we needed to choose the right viewer to ensure optimal user experience for accessing digital collections. After extensive testing of the available options, we selected Mirador over Universal Viewer for a number of compelling reasons:

1. Faster Image Loading

Mirador outperformed Universa Viewer in loading high-resolution images, providing a smoother user experience.

2. Modern Interface

Its clean, modern design offers easy navigation and a visually engaging way to explore digital collections.

3. Advanced Features

Mirador supports useful tools like annotations, OCR overlays, and image adjustments (brightness,... read more

IIIF

The International Image Interoperability Framework (IIIF) is a set of open standards that is widely used by cultural heritage institutions to facilitate sharing, displaying and annotation of high-resolution digital images. It allows users to access, compare, and interact with images across various platforms seamlessly. IIIF consists of a set of APIs that deliver functionality.

Omeka S

Omeka S is a web publishing platform designed for institutions to manage and share digital collections and exhibits. It supports linked data, enabling the creation of interconnected content across multiple sites, making it ideal for collaborative projects and multi-institutional archives.
