== Semantic annotation for 3D cultural artefacts ==
A suite of tools for semantic annotation of 3D cultural artefacts is being developed as part of the [https://nfdi4culture.de/ NFDI4Culture] project across several partner organisations (led by the [https://www.tib.eu/de/forschung-entwicklung/forschungsgruppen-und-labs/open-science Open Science lab at TIB, Hannover]). Operating within Task area 1: Data capture and enrichment, the proposed toolchain focuses on the annotation of 3D data within a knowledge graph environment, so that 3D objects’ geometry, attendant metadata, as well as annotations remain searchable, while data interconnections are not lost. The project builds on several existing FOSS tools: 
* [https://openrefine.org/ OpenRefine], a data cleaning, reconciliation and batch upload tool; 
* [https://wikiba.se/ Wikibase] (the tool behind the interface you are viewing now), a suite of services developed by Wikimedia Germany; it combines the ability to handle large volumes of data points with sophisticated data querying and extraction services via a dedicated SPARQL endpoint;
* [https://kompakkt.de/home Kompakkt], a browser-based open-source 3D- and multimedia viewer Kompakkt with built-in collaborative annotation features.

The integrated suite of tools follows FAIR principles and facilitates linking 3D-objects and annotations, and their cultural context (including historical people and places, geo-location and capture-technology metadata), to the broader semantic web and various national and international authority records (GND, VIAF and more). 

== About our case study ==
This Wikibase instance contains sample data about Weikersheim Castle from the [http://www.deckenmalerei.eu/42d06165-58e7-4653-bfe4-3d5f7091fc33 Corpus der barocken Deckenmalerei in Deutschland], provided the MVP data partners at [https://www.kunstgeschichte.uni-muenchen.de/index.html The Institute of Art History] at Ludwig-Maximilians-Universität in Munich.
