New and Emerging Specs and Standards (March 2022)

ISO/IEC/IEEE 29119-1:2022 Software and systems engineering — Software testing — Part 1: General concepts
Technical Committee: ISO/IEC JTC 1/SC 7 Software and systems engineering

"This document specifies general concepts in software testing and presents key concepts for the ISO/IEC/IEEE 29119 series. This second edition cancels and replaces the first edition (ISO/IEC/IEEE 29119-1:2013), which has been technically revised. The main changes are as follows: testing terms and their definitions that are not covered within this document have been removed. This has led to this document being renamed from ‘Concepts and definitions’ to ‘General concepts’; the coverage of test concepts has been made more concise and re-ordered; the concept of test sub-processes has been removed due to its complexity and replaced with additional coverage of the instantiation of test processes; the expected content of a test strategy has been clarified; a simplified test design process is described, with the derivation of test cases now based on test models rather than on test conditions; the coverage of metrics and measures has been moved from an annex into the body of the document; the annex explaining how testing fits into different life cycle models has been removed; and a new annex providing examples of how systems from different domains are associated with certain characteristics and test approaches has been added."

ISO 23257:2022 Blockchain and distributed ledger technologies — Reference architecture

Technical Committee: ISO/TC 307 Blockchain and distributed ledger technologies

"This document specifies a reference architecture for Distributed Ledger Technology (DLT) systems including blockchain systems. The reference architecture addresses concepts, cross-cutting aspects, architectural considerations, and architecture views, including functional components, roles, activities, and their relationships for blockchain and DLT. […] Currently, it is possible to achieve a verifiable ledger in a centralized way by making certain trust assumptions. However, verifiability can be also achieved by distributing the storage and decentralizing the control of the ledger with minimal trust in any one party. By maintaining a ledger in a distributed network, Distributed Ledger Technology (DLT) systems, including blockchain systems, allow a much wider range of parties to have a shared view of the ledger and to make their own changes to that ledger. A broad spectrum of DLT based business solutions is possible. This document presents a reference architecture for such DLT based solutions. It starts with the definitions and concepts of blockchain and DLT such as the system organization, nature of access, type of consensus and the roles and responsibilities of the participants. Given that the reference architecture must accommodate a wide variety of possible use cases, it touches upon various business domains and their respective use cases at a high level. Historically, ledgers have facilitated the exchange of assets, but DLT solutions can also be used more broadly for reporting, auditing, and coordination. The document finally presents the reader with various layers of a reference architecture for DLT systems and the functional components in the layers.

This document is relevant to, among other, academics, architects, customers, users, developers, regulators, auditors, and standards development organizations."

Library Binding Symposium Recording Now Available (ALA Core)

"In January 2022, the free Core Symposium on the Future of Library Binding featured updates from the LOC Preservation Directorate, perspectives on the state of the industry, and a discussion on current practice and the need to pivot in response to changing commercial binding landscape. Focusing discussion on the current crisis facing the binding industry and its impact on library binding, the symposium addressed the state of the industry, library binding standards, and current practices in view of these impending changes."

CRCC Update Forum on Continuing Resources Recording Now Available (ALA Core)

"The recording of our popular Continuing Resources Cataloging Committee (CRCC) Forum is now available. This event offered a venue for catalogers and serialists to gather and share ideas and updates within the continuing resources community. [Speakers included] Regina Reynolds, Director, U.S. ISSN Center at the Library of Congress; Paul Frank & Melanie Polutta, both with Policy, Training, and Cooperative Programs Division, Library of Congress; Hien Nguyen, CONSER Coordinator, Cooperative Programs and Policy Section Head, Library of Congress; Steve Shadle, Head of Serials Cataloging, University of Washington, who presented on the Directory of Open Access Journals (DOAJ)."
