WG 6.2 – Handling 3D-data and metadata of the digitized entities – Terms of Reference

Scope and Objectives

TA6, together with WG 6.2, analysed data handling in two ways: 1) data handling of 3D data in general; 2) interlinking between the 3D-data and Metadata describing the digitized entities. To gain a deeper understanding, TA6 worked on a descriptive list of characteristics of 3D-data to identify peculiarities.

This list considered the following columns: Name of characteristic (e.g. size, environment,) / Applied to 3D in general (e.g. description of size, description if/what environment is generally needed). This list was published in the ViMM-platform. TA6 (with WG 6.2) also analysed the possible ways for getting metadata for the 3D objects grouped with metadata for the digitized objects (e.g. is there a container-metadata-format or has a database to be used or …). This analysis was published on the ViMM-platform.

WG6.2 had the following scope and objectives:

  • To create an overview of available tools and technologies surrounding 3D data handling and metadata that are, can or should be used by CH.


To achieve this, it created and assessed (items on) a list concerning five topics. These were:

  • Data provenance (Museums, society, association)
  • Format (computer format, translations, conversion)
  • Storage (databases, centralization, modularity, cloud-based)
  • Architecture of data (hierarchical, tabular)
  • Technologies (software programming languages, hardware, etc.)


The outcome of this work included:

A list of best practices and state of the art examples of structure, architecture, formats, user interaction and technologies used in 3D metadata handling. It also include an analysis of said practices and examples too.
