# Herrenhauszentrum des Ostseeraums: Das Webportal

This source describes the technical architecture and conceptual goals of the interactive web portal developed by the [[herrenhauszentrum-des-ostseeraums]] in collaboration with the Open Science Lab of [[TIB-Hannover]].

## Technical Architecture
The portal utilizes a "pioneer" combination of software solutions provided by **Wikimedia Deutschland**:
- **Backend:** A [[wikibase]] instance used for the semantized capture of research data.
- **Frontend:** [[semantic-mediawiki]], which handles the user-oriented presentation of content via templates and specialized search functions (location-centered and person-centered).

## Data Modeling and Interoperability
The data model was developed by TIB Hannover to ensure high interoperability. It is mapped to:
- **Wikidata:** To align with existing global data structures.
- **[[CIDOC-CRM]]:** To adhere to the conceptual reference model for cultural heritage information.

## 3D Visualization and Imaging
The portal integrates the **Kompakkt-3D-Viewer** into its workflow for importing and annotating imaging data. It supports a variety of heterogeneous and cutting-edge visualization formats, including:
- Point clouds.
- **NeRFs** (Neural Radiance Fields).
- **Gaussian Splatting**.

Rather than using 3D images as mere illustrations, the portal employs them as interactive, annotated orientation markers to evoke a sense of spatial perception for the visitor.
