Are you searching for a technical platform for your digital image collection?

One of the University Library Heidelberg’s services in Propylaeum to classical scholars worldwide is the provision of technical infrastructure for the publication and archiving of digital image collections.

Image data and multimedia objects are among the most important working tools within the fast growing field of digital humanities. With heidICON Propylaeum provides a digital and interdisciplinary image and multimedia repository customized for the requirements of the respective file formats.

heidICON is based on the software easydb developed by the company programmfabrik (Berlin). In early 2019 heidICON migrated to the new software easydb 5 and in the course of this migration was converted from its former image oriented recording towards a hierarchical, object oriented form of data management, in accordance with international Standard LIDO (Lightweight Information Describing Objects). The data scheme was created by Working Group Data Harvesting and Interchange, a task force of the International Committee on Documentation (CIDOC). Apart from a significant improvement in the search options on the basis of search engine technology and a modern user interface easydb 5.x offers a fully revised authorization concept. In the future, all features in heidICON can be operated via an extensive application programming interface (API).

heidICON also serves as an aggregator data base connecting national and international research reference tools such as  prometheus, Deutsche Digitale Bibliothek (DDB) orr Europeana.

At the University Library Heidelberg we offer introductions to heidICON, its use, functions and working
