- The **Image API** provides a standard way to request and deliver image content over the web. It defines a consistent URL structure and a set of parameters that can be used to request images in different formats, sizes, rotations, and quality levels. The Image API enables clients to request only the required portion of an image, which optimizes bandwidth usage and improves performance. It also supports dynamic generation of image derivatives, eliminating the need for institutions to pre-generate and store multiple versions of each image.
- The **Presentation API** is responsible for conveying the structure, layout, and descriptive metadata of a digital object (such as a book, manuscript, or photograph album). It provides a standardized JSON-LD format for representing the structure of compound digital objects (named *manifest*), that includes information about image sequences, navigation, and related resources. The Presentation API allows viewers to understand how to display and navigate the images in their proper context. Additionally, the Presentation API can be used to enrich digital objects with transcriptions, tags, and temporal or geographical information.

### Comparison IIIF Image API to web maps:
## How does the IIIF Image API compare to web maps?
The working of the IIIF Image API can be compared to web maps. When users open a world map on a device (such as [Open Street Map](https://www.openstreetmap.org)), they see a tiny part of a gigantic image. This image is sliced into square parts, named *tiles*, which are created for different zoom levels (and are often differentiated for each level). Based on the viewport of the user’s device, only the necessary tiles are loaded, and stitched together (this explains the loading of maps in a chessboard pattern). While map webs work with a geographic coordinate system, the IIIF Image API uses the cartesian coordinate system of the pixels in the image.

## How to add semantic metadata to a IIIF manifest?
The primary purpose of a IIIF manifest is to describe the structure and presentation of images and their associated resources. It is not designed to store or manage detailed semantic metadata about the content of the images. The focus is on interoperability and ensuring that images can be easily displayed and navigated in a variety of viewing environments. The aim of the label and metadata properties contained in a IIIF manifest is the presentation to end users; not machine processing. The only semantics it contains are language codes.

See:
https://iiif.io/api/presentation/3.0/#11-objectives-and-scope

However, IIIF does support linking to external resources that may contain semantic metadata. In a IIIF manifest, you can include links to other descriptive resources like metadata records, annotation lists, or external vocabularies using the [seeAlso](https://iiif.io/api/presentation/3.0/#seealso) property. This allows institutions to maintain and manage their semantic metadata separately from the IIIF manifest, while still making it accessible and discoverable in the context of the images.

## Which viewers can I use once I have implemented IIIF?
Once you have implemented IIIF, there are several popular IIIF-compatible viewers that you can use to display and interact with your digital images. These viewers support the IIIF Presentation API and Image API, offering a range of features for navigating, zooming, and annotating digital objects. Some widely used IIIF viewers include:

- **[Mirador](https://projectmirador.org/)**: Mirador is an open-source, multi-window viewer that supports side-by-side comparison of multiple images, annotation functionality, and deep zoom. It is highly customizable and can be embedded in web pages or used as a standalone application.
- **[Universal Viewer](https://universalviewer.io/)**: Universal Viewer is an open-source, extensible, and customizable viewer that provides a user-friendly interface for displaying images, audio, video, and other media formats. It supports deep zoom, full-text search, and various layout options.
- **[OpenSeadragon](https://openseadragon.github.io/)**: OpenSeadragon is an open-source, web-based viewer that focuses on providing deep zoom capabilities and smooth navigation for high-resolution images. Although it does not natively support IIIF Presentation API manifests, plugins like the [OpenSeadragon IIIF plugin](https://github.com/openseadragon/openseadragon-iiif) can enable this functionality.
- **[Leaflet-IIIF](https://github.com/mejackreed/Leaflet-IIIF)**: Leaflet-IIIF is an extension of the popular Leaflet mapping library that adds support for IIIF Image API, allowing you to display and interact with images using familiar map-like interactions. It is lightweight and suitable for projects that require a more straightforward viewer without extensive features.
- **[Diva.js](https://ddmal.github.io/diva.js/)**: Diva.js is an open-source document image viewer that supports IIIF and focuses on providing a fast, scalable, and responsive user experience. It is designed for applications that require the display and navigation of high-resolution images from manuscripts, books, and other digitized documents.
- **[IIIF Curation Viewer](https://github.com/utokyo-iiif/iiif-curation-viewer)**: IIIF Curation Viewer is an open-source viewer that supports IIIF Presentation API and allows users to create, edit, and share IIIF manifests. It provides annotation functionality and enables users to curate digital objects from various sources into a single IIIF manifest.
- **[FromThePage](https://fromthepage.com/)** is a web-based platform for collaborative manuscript transcription, translation, and indexing. While it is not primarily a IIIF viewer like Mirador or Universal Viewer, it does support IIIF integration, allowing users to work with digital images hosted on IIIF servers. FromThePage's main focus is to facilitate the transcription and annotation of historical documents, manuscripts, and other digitized texts by multiple users.
- **[Allmaps](https://allmaps.com/)** is a web-based platform for creating interactive maps and geospatial applications using various mapping technologies, including IIIF. While Allmaps is not primarily a IIIF viewer like Mirador or Universal Viewer, it supports IIIF integration, allowing users to work with high-resolution images hosted on IIIF servers as map layers.
