Tutorial: How to create a Linked Open Data service and semantic portal for your Cultural Heritage data

Thursday, November 28, 2024, 13:00–16:00 (12:00-15:00 CET)
Aalto University, Espoo, TUAS-house, Maarintie 8, 1007a Learning Hub Atrium (ground floor) and
via Zoom

Learning objectives

Since 2002, the Semantic Computing Research Group (SeCo) has been involved in 1) developing a national semantic web infrastructure and 2) the "Sampo series" of over 20 Linked Open Data (LOD) services and semantic portals on top of them in use on the Web. This work goes on today as part of the national DARIAH-FI research infrastructure program, pertaining to the LOD work package led by the SeCo group. The goal of this tutorial is to explain in practice how the models, tools, datasets, and portals developed can be used for creating new data services and applications for Digital Humanities research, based on one's own data available in different formats.

"Sampo" is a mythical device playing a central role in the Finnish epic Kalevala. According to a popular interpretation, it is regarded as a metaphor of amazing ancient technology.
