Metadata for 3D Digital Heritage Models. In the Search of a Common Ground

The publication of 3D models has been an unregulated issue for many years. Recently, it has been possible to identify barriers that have prevented the proper preparation of 3D data for web-based publication, related to uncleared copyright issues, access to 3D files, targeted audiences, or distinction of requirements related to different stages of the digital asset lifecycle. In response to these challenges, numerous scientific infrastructures with diverse backgrounds and purposes have emerged, presenting different approaches to metadata documentation schemes. This publication aims to present an analysis of existing metadata schemas carried out in a workshop with selected initiatives and digital data repositories on metadata for digital heritage to find the common grounds between the various metadata schemas. The compilation of multiple documentation schemas is used to develop an approach for the creation of a universal documentation metadata patterns that could guide the work on the standardisation of 3D models of cultural heritage.
