Incipit Search

Incipit Search icon

Music search is an exciting field of research and development with different approaches. Above all, there is the question of annotation and encoding to make music searchable.

With IncipitSearch we have developed a portal for searching melodies in collections of classical music. It connects content from different music editions and libraries using metadata. The ontology “Schema.org” and the library standard “Plaine & Easie Code” serve as the underlying encoding to make the sheet music searchable. Notes are entered using a virtual keyboard or the encoding.

Developed as part of a research project at the Academy of Sciences and Literature.

Digitalization in science and research is taking place at many institutes and in various projects. The goal of the National Research Data Infrastructure, funded by the German Federal Ministry of Education and Research, is to bundle these different efforts.

Julius supported the development of an information portal for the Consortium for Research Data on Material and Immaterial Cultural Heritage (NFDI4Culture) with backend programming using TYPO3 and collaborated with a team of researchers and a digital agency.

Macarons icon

Team spirit is crucial to every work environment. But hybrid and remote teams don't meet accidentally at the coffee machine anymore. With Macarons we created a minimalistic coffee roulette app for Slack that automatically matches random team members for casual chat.

To get started, Macarons simply needs to be added to a Slack channel. Built-in ice breaker questions make for an easy conversation starter.

Virtual tour through a UNESCO World Heritage cathedral

Virtual tour through a UNESCO World Heritage cathedral icon

To admire architecture and glorious buildings directly on site is the most beautiful experience. This is true for tourist trips, but also for science, when spatial impressions or arrangements are significant for the interpretation of sources and actions. However, it is not always possible to be on site. Therefore, we have developed a generic software for virtual tours through cultural heritage sites.

One implementation is a virtual tour through the UNESCO World Heritage Site Hildesheim Cathedral. The tour provides information about history and furnishings of the church. Developed in the context of a research project of the Academy of Sciences and Literature, the tour was also shown as part of a museum exhibition.
