  • Response by the Polar Data Community to the OGC Request for Information on Arctic Spatial Data
    Response to the Open Geospatial Consortium Request for Information on Arctic Spatial Data by the Polar Data Community March 24, 2016 Overview The polar data community welcomes the recent Request for Information (RFI) on Arctic spatial data interoperability and infrastructure issued by the Open Geospatial Consortium (OGC). The OGC’s interest in this topic is timely since, as we will discuss below: . The polar regions are of increasing interest to the whole world as a result of their linkage to global climate systems, opportunities for economic development, geo-political strategic importance, and their environmental importance as homes to Indigenous populations and other residents and sensitive ecosystems. Polar data are required by the scientific community and residents to support research on topics such as climate, atmosphere, land, oceans, ecosystems, ice and snow, permafrost, and social systems; and by the operations community to support impact assessments, engineering design, safe navigation and operations, risk management, emergency response, weather forecasting, and climate change adaptation. These activities contribute to environmental protection, heritage preservation, economic development, safety of life and property, and national sovereignty. The polar data community is well organized and is pursuing activities to improve data management for all of the diverse members of the polar community. Polar data infrastructure is evolving from a system where data are discovered in data catalogues and downloaded to the local machines of users, to a system of distributed data made interoperable using standards and providing users with storage and computational capacity close to large repositories of data. Indigenous Peoples of the Arctic and their representative organizations are increasingly active in using information and communications technologies (ICT) to access data and share their information and knowledge.

  • USGS Guidelines for the Preservation of Digital Scientific Data
    April 2014 USGS Guidelines for the Preservation of Digital Scientific Data Introduction This document provides guidelines for use by USGS scientists, management, and IT staff in technical evaluation of systems for preserving digital scientific data. These guidelines will assist in selecting, specifying, building, operating, or enhancing data repositories. The USGS Fundamental Science Practices Advisory Committee – Data Preservation Subcommittee developed these guidelines based on material from the Library of Congress-sponsored National Digital Stewardship Alliance (National Digital Stewardship Alliance, 2013). This document does not cover additional non-technical issues such as preservation policies, funding, or organizational competency and longevity, which are critical for data preservation, but beyond the scope of this document. More information about this topic can be found in Trustworthy Repositories Audit & Certification: Criteria and Checklist (OCLC-NARA, 2007)1. When considering how to preserve digital data you should address these questions: • Where are the data stored? • Do you store a copy of the data off-site? • How do you ensure the integrity of the data over time? • What IT security features does USGS require for storing and accessing the data? • What additional IT security features do you need? • What metadata standard should be used to document the data? • What sustainable file formats should be used for long-term storage? • What are the applicable USGS rules regarding record retention periods for the data?2 • Who can you ask for assistance? USGS Digital Science Data Preservation Guidelines Page 1 April 2014 Table Element Definitions Each row in the table below represents a technical element of digital data preservation. • Storage & Geographic Location – Storage systems, locations, and multiple copies to prevent loss of data.

  • A DIY Approach to Digital Preservation
    Practical Digital Solutions: A DIY Approach to Digital Preservation by Tyler McNally A Thesis Submitted to the Faculty of Graduate Studies of the University of Manitoba In Partial Fulfillment of the Requirements of the Degree of MASTER OF ARTS Department of History (Archival Studies) Joint Masters Program University of Manitoba/University of Winnipeg Winnipeg, Manitoba Copyright © 2018 by Tyler McNally Table of Contents Abstract…………………………………………………………...i AcknoWledgments…………………………………………….ii Acronym IndeX…………………………………………………iii Introduction……………………………………………………..1 Chapter 1………………………………………………………….12 Chapter 2………………………………………………………….54 Chapter 3………………………………………………………….81 Conclusion ……………………………………………………….116 Bibliography……………………………………………………..125 iii Abstract Since the introduction of computers, archivists have had to find ways to deal with digital records. As more records are born digital (created through digital means) and digital technologies become more entrenched in hoW data is created and processed, it is imperative that archivists properly preserve these records. This thesis seeks to propose one possible solution to this issue. Rather than advocate for paid solutions or electronic record management systems, it advocates for more practical in-house DIY solutions. The first chapter lays out background information and the historiography of digital archiving in Canada at the federal level. The second chapter moves step-by-step through a Workflow developed at the University of Manitoba’s Faculty of Medicine Archives that lays out one possible DIY style solution. The third chapter is an audit of the WorkfloW from the second chapter against three important international standards for preserving digital information. iv Acknowledgments I would like to acknoWledge and thank Professors Thomas Nesmith and Greg Bak. Their role as professors of the Archival Studies program has been a great source of support and inspiration as well as their knowledge and passion for both archives and their students.
