CHER-Ob: An Open Source Platform for Shared Analysis in Cultural Heritage Research

CHER-Ob (CULTURAL HERITAGE-Object) is an open source platform developed in an attempt to enhance analysis, evaluation, documentation, sharing and management of 3D and 2D visualizations as well as textual and conservation science data.


The development of CHER-Ob is intended to offer a flexible, expandable integrated platform for collaborative cultural heritage research. It is compatible with commonly used imaging data types (2D and 3D images, RTIs, CT) and textual information. CHER-Ob offers an enhanced annotation framework and metadata schema, automatic report generation, bookmark, screenshot, searching, sorting and filtering options.

For a quick intro to CHER-Ob please see the quick guide. For a detailed explanation of the features see manual.  You can also download the sample projects to further explore the software.
