Next Generation Repositories: Behaviours and Technical Recommendations of the COAR Next Generation Repositories Working Group

Description: The widespread deployment of repository systems in higher education and research institutions provides the foundation for a distributed, globally networked infrastructure for scholarly communication. However, repository platforms are still using technologies and protocols designed almost twenty years ago, before the boom of the Web and the dominance of Google, social networking, semantic web and ubiquitous mobile devices.In April 2016, COAR launched the Next Generation Repositories Working Group to identify the core functionalities for the next generation of repositories, as well as the architectures and technologies required to implement them. This report presents the results of work by this group over the last 1.5 years. The Next Generation Repositories Working Group has explicitly focused on the generic technologies required by all repositories to support the adoption of common behaviors. This report describes 11 new behaviors, as well as the technologies, standards and protocols that will facilitate the development of new services on top of the collective network, including social networking, peer review, notifications, and usage assessment. 1. Exposing Identifiers 2. Declaring Licenses at a Resource Level 3. Discovery through Navigation 4. Interacting with Resources (Annotation, Commentary and Review) 5. Resource Transfer 6. Batch Discovery 7. Collecting and Exposing Activities 8. Identification of Users 9. Authentication of Users 10. Exposing Standardized Usage Metrics 11. Preserving Resources The behaviors and technologies in this report are a snapshot of the current status of technology, standards and protocols available, but we are aware that technologies will continue to evolve.

National Digital Stewardship Alliance Web Archiving Survey Report: 2012

Description: The National Digital Stewardship Alliance is a member organization whose mission is to establish, maintain, and advance the capacity to preserve our nation's digital resources for the benefit of present and future generations. From October 3 through October 31, 2011, the Content Working Group conducted a survey of organizations in the United States that are actively involved in, or planning to start, programs to archive content from the web. The goal of the survey was to better understand the landscape of web archiving activities in the United States, including identifying the organizations or individuals involved, the types of web content being preserved, the tools and services being used, and the types of access being provided. This summary report examines participant responses for the purposes of discerning trends, themes, and emerging practices and challenges in web-based content acquisition and preservation.

Web Archiving in the United States: A 2016 Survey

Description: The National Digital Stewardship Alliance is a member organization whose mission is to establish, maintain, and advance the capacity to preserve our nation's digital resources for the benefit of present and future generations. From January 20 to February 16, 2016, a team of individuals representing multiple NDSA member institutions and interest groups conducted a survey of organizations in the United States actively involved in, or planning to start, programs to archive content from the Web. This effort built upon a similar survey undertaken by NDSA in late 2011 and published online in June 2012 and a second survey in late 2013 published online in September 2014.The goal of these surveys is to better understand the landscape of Web archiving activities in the United States by investigating the organizations involved, the history and scope of their Web archiving programs, the types of Web content being preserved, the tools and services being used, access and discovery services being provided, and overall policies related to Web archiving programs.

Web Archiving in the United States: A 2013 Survey

Description: The National Digital Stewardship Alliance is a member organization whose mission is to establish, maintain, and advance the capacity to preserve our nation's digital resources for the benefit of present and future generations. From October through November of 2013, a team of individuals representing multiple NDSA member institutions and Working Groups conducted a survey of organizations in the United States that are actively involved in, or planning to start, programs to archive content from the Web. This effort builds upon a similar survey undertaken by the NDSA in late 2011 and published online in June of 2012. The goal of the survey was to better understand the landscape of web archiving activities in the U.S. by investigating the organizations involved, the history and scope of their web archiving programs, the types of web content being preserved, the tools and services being used, access and discovery services being provided, and overall policies related to web archiving programs.

TMI-2 lower head creep rupture analysis

Description: The TMI-2 accident resulted in approximately 40% of the reactor's core melting and collecting on the lower head of the reactor pressure vessel. The severity of the accident has raised questions about the margin of safety against rupture of the lower head in this accident since all evidence seems to indicate no major breach of the vessel occurred. Scoping heat transfer analyses of the relocated core debris and lower head have been made based upon assumed core melting scenarios and core material debris formations while in contact with the lower head. This report describes the structural finite element creep rupture analysis of the lower head using a temperature transient judged most likely to challenge the structural capacity of the vessel. This evaluation of vessel response to this transient has provided insight into the creep mechanisms of the vessel wall, a realistic mode of failure, and a means by which margin to failure can be evaluated once examination provides estimated maximum wall temperatures. Suggestions for more extensive research in this area are also provided. 6 refs., 15 figs.

Project Management Plan

Description: The mission of the Uranium Mill Tailings Remedial Action (UMTRA) Project is explicitly stated and directed in the Uranium Mill Tailings Radiation Control Act of 1978, Public Law 95-604, 42 USC 7901 (hereinafter referred to as the Act''). Title I of the Act authorizes the Department of Energy (DOE) to undertake remedial actions at 24 designated inactive uranium processing sites and associated vicinity properties containing uranium mill tailings and other residual radioactive materials derived from the processing sites. The Act, amended in January 1983, by Public Law 97-415, also authorizes DOE to perform remedial actions at vicinity properties in Edgemont, South Dakota. Cleanup of the Edgemont processing site is the responsibility of the Tennessee Valley Authority. This document describes the plan, organization, system, and methodologies used to manage the design, construction, and other activities required to clean up the designated sites and associated vicinity properties in accordance with the Act. The plan describes the objectives of the UMTRA Project, defines participants' roles and responsibilities, outlines the technical approach for accomplishing the objectives, and describes the planning and managerial controls to be used in integrating and performing the Project mission. 21 figs., 21 tabs.
