Presenting SIPI, a versatile IIIF Image API 3 Server

  • 1. Data & Service Center for the Humanities (DaSCH)

Description

The Simple Image Presentation Interface (SIPI) is a multithreaded, high-performance, IIIF compatible media server developed by the Data and Service Center for the Humanities (DaSCH) at the University of Basel. It is designed to be used by archives, libraries, and other institutions that need to preserve high-quality images while making them available online.

SIPI has implemented the IIIF Image API 3.0, and efficiently converts between image formats, preserving metadata contained in image files. In particular, if images are stored in JPEG 2000 format, SIPI can convert them on the fly to formats that are commonly used on the Internet. It offers a flexible framework for specifying authentication and authorisation logic in Lua scripts.

In addition SIPI preserves most of the EXIF, IPTC and XMP metadata and can preserve or transform ICC colour profiles. SIPI is free software, released under the GNU Affero General Public License. It is written in C++ and runs on Linux and Mac OS. For the time being, the user has to provide a licensed source of the kakadu software to compile SIPI.

This lightning talk given at the 2021 IIIF Annual Conference was an opportunity to present the main functionalities of SIPI and to give hints on future developments.
