Web-Client

The Web-Client

The web-client contains the search engine that permits access to the repository. It is divided in a work-space and the clipboard where objects of interest can be saved and grouped.

Search-Engine

In the work-space queries can be composed in a versatile highly adaptive manner using concepts derived from CIDOC CRM. The user can select two key concepts (Actor, Place, Event, Thing, Time, Concept or Class) and define the relationship between them (e.g. search for a Thing from a specific Place). Search results can be browsed and refined further through additional filters.

View

Single objects from the search results can be explored in more detail by looking at their metadata, photographs and a preview of their 3D model. It is also possible to look for similar objects to the one selected based on semantic or geometric properties.

Metadata display

In the metadata display a user can inspect photographs and the available information on an object structured in a CIDOC CRM inspired way. More information can be added to the different CIDOC CRM metadata categories (e.g. material, type) and an opinion can be expressed on the already available information.

Semantic and geometric similarity search

The aim of these queries is to find other pieces that share with the selected object one or a combination of similar characteristics chosen by the user. For the semantic similarity search these characteristics are: material, type, decoration, production time and place, symbol and physical features. The geometric search permits to look for objects that have a similar overall shape, size, colour, or roughness as well as a similar 2D or 3D decoration. As most fragments exhibit a different appearance on their external and internal side (e.g. colour, roughness) it is possible to improve search results by restricting the search to the ”interesting” side of a fragment.

3D preview

In the 3D preview low resolution models of 50k and without colour information can be inspected to gain a first understanding of the shape and geometric features of an object.
