The fellowship tackles the lack of international, or European, standard or technical specification that focuses explicitly on privacy and data protection capabilities of DLT systems. With this regards, ISO TS 24946 “Requirements and guidance for improving, preserving, and
assessing the privacy capability of DLT systems” has now reached CD stage (July 2025) and will endeavour to move through this process and be completed in 2026. This process requires continued support from experts to ensure delivery, as scheduled. In this sense, the priority of this activity focuses at the European level, CEN/CENELEC JTC 19/WG3 to produce a European standard on PII protection within DLT which is strongly influenced by ‘DIN Spec 4997 - Privacy by Blockchain Design’ and the aforementioned ISO TS 24946. This European specification will seek to harmonise the GDPR and recent EDPB guidance to produce a technical specification intended for the European DLT ecosystem.
This European specification will provide much needed clarity for the DLT ecosystem as regards data protection and privacy capabilities, affordances, and assessment. Further harmonisation between the international specification at ISO and the European standard will support interoperability, and ensure that privacy and data protection capabilities are harmonised globally. The main challenges concerns exacting requirements from regulations such as Article 76(3) of MiCAR, as well as Article 79(1) of the European AMLR will require navigation. Standards
require alignment and compatibility with those legal texts, as well as corresponding regulations regarding personal data, data markets, and trust services (e.g., GDPR, Data Act, eIDAS2). Ensuring there are no gaps between regulatory texts and the proposed European standards will be a primary focus. Also, it must be ensured that there are no substantial gaps between international specifications and European standards will be the second focus. Standards alignment between ISO and CEN/CENELEC is viewed as a key outcome to benefit the global DLT ecosystem, and one that requires strong consensus building, given slightly different international privacy perspectives and preferences.
The technologies of this document specified are description languages and vocabularies to describe virtual world objects. The adaptation engine is not within the scope of this document. This document specifies syntax and semantics of the tools used to characterize a virtual world object related metadata: Virtual World Object Characteristics (VWOC) as an XML Schema-based language which enables one to describe a basic structure of avatars and virtual world objects in virtual environments.
ISO/IEC 19776-3:2015, Extensible 3D (X3D), defines a system that integrates 3D graphics and multimedia. Conceptually, each X3D file is a 3D time-based space that contains graphic and aural objects that can be dynamically modified through a variety of mechanisms. This part of ISO/IEC 19776 defines a mapping of the abstract objects in X3D to a specific X3D encoding written out in a compact binary form. Each X3D file encoded using the Compressed binary encoding:a. supports all of the purposes of X3D files defined in the X3D abstract specification ISO/IEC 19775; andb. encodes X3D constructs in a compressed binary format, taking advantage of geometric and information-theoretic compression techniques.X3D files encoded using the Compressed binary encoding may be referenced from files using other X3D encodings, and may itself reference other X3D files encoded using other X3D encodings. Sets of X3D files that use multiple encodings can only be processed by browsers that support all of the utilized X3D encodings.

This document specifies extensions to existing scene description formats in order to support MPEG media, in particular immersive media. MPEG media includes but is not limited to media encoded with MPEG codecs, media stored in MPEG containers, MPEG media and application formats as well as media provided through MPEG delivery mechanisms. Extensions include scene description format syntax and semantics and the processing model when using these extensions by a Presentation Engine. It also defines a Media Access Function (MAF) API for communication between the Presentation Engine and the Media Access Function for these extensions. While the extensions defined in this document can be applicable to other scene description formats, they are provided for ISO/IEC 12113.
