New and Emerging Specs & Standards (September 2025)
ISO/IEC 16466:2025 – Information technology — 3D printing and scanning — Assessment methods of 3D scanned data use in 3D printing
Technical Committee: ISO/IEC JTC 1
“This document specifies methods and metrics for assessing the accuracy and precision of 3D scanned data for use in 3D printing, throughout the full 3D printing lifecycle. This document focuses mainly on 3D scanned data from computed tomography. Computed tomography can acquire information concerning the internal structures, regional density, orientation and/or alignment of scanning objects, as well as their shape and appearance. This document is applicable to the assessment of image-based modelling, segmentation, and 3D models. This document is not intended to assess the 3D printed product itself.”
ISO/IEC 12087-5:2025 – Information technology — Image processing and interchange (IPI) functional specification Part 5: Basic image interchange format (BIIF)
Technical Committee: ISO/IEC JTC 1/SC 24
“This document establishes the specification of the Basic image interchange format (BIIF). This document provides a foundation for interoperability in the interchange of imagery and imagery-related data among applications. It also provides a detailed description of the overall structure of the format, as well as specification of the valid data and format for all fields defined with BIIF. Annex C contains a Model Profile of BIIF in tables to assist in profile development. The scope and field of application of this document includes the capability to perpetuate a proven interchange capability in support of commercial and government imagery, Programmer’s Imaging Kernel System (PIKS) data, and other imagery technology domains in that priority order. This document provides a data format container for image, symbol, and text, along with a mechanism for including image-related support data. This document provides a means whereby diverse applications can share imagery and associated information; allows an application to exchange comprehensive information to users with diverse needs or capabilities, allowing each user to select only those data items that correspond to their needs and capabilities; minimizes preprocessing and postprocessing of data; minimizes formatting overhead, particularly for those applications exchanging only a small amount of data and for bandwidth-limited systems; provides a mechanism (Transportable File Structure, TFS) to interchange PIKS image and image-related objects; provides extensibility to accommodate future data, including objects.”
W3C Invites Implementations of Accessibility Conformance Testing (ACT) Rules Format 1.1 [W3C]
“The Accessibility Guidelines Working Group has published Accessibility Conformance Testing (ACT) Rules Format 1.1 as a W3C Candidate Recommendation Snapshot. Act Rules Format defines a format for writing accessibility test rules that can be used for developing automated testing tools and manual testing methodologies. For an introduction to Accessibility Conformance Testing, see the ACT Overview. Comments are welcome via Github issues or email to public-wcag-act@w3.org by 20 October 2025.”
Library Swarm Intelligence Session [ALA Core]
“On September 18th, with the power of AI, we will empower over 200 librarians to brainstorm opportunities for the library world. Using a tool called Thinkscape, we can create a virtualized brainstorming session for rapid solution-making.”
RDA Communications Bulletin, August 2025 [LoC PCC]
“The bulletin provides updates on PCC's efforts towards implementing the official RDA Toolkit, including Description Convention Source Codes; Describing Fictitious and Non-Human Entities; New Relationship Labels Spreadsheet; RDA Workshop at ALA Annual; Representative Expression Elements; New String Encoding Scheme MGDs; Tips for Using the RDA Toolkit.”
