  Summary of Data curation preservation issues (Organisational Issues). Introduction Digital curation, also known as data curation, represents the systematic process of maintaining, preserving, and enhancing digital research information across its entire lifespan (Digital Curation Centre, 2017). In practical terms, it serves as a dynamic data management practice that links datasets to facilitate subsequent analysis and conclusion-drawing. The Graduate School of Library and Information Science at the University of Illinois defines data curation as the proactive and continuous administration of data for as long as it remains valuable to academic research, science, and education. These curation practices streamline data discovery and retrieval, safeguard quality, enrich utility, and ensure ongoing reusability by incorporating crucial functions such as verification, archival storage, governance, long-term preservation, recovery, and structured representation. Funding, resource Co...

Digital curation process Introduction Digital preservation and curation ensure that diverse electronic resources remain accessible, authentic, and understandable over time. As reliance on digital storage grows, protecting these assets becomes critical. However, constant threats compromise long-term data integrity, making an understanding of these challenges fundamental to developing sustainable curation strategies (Corrado & Sandy, 2017). Rapid technological obsolescence and physical media deterioration severely threaten digital materials. Evolving systems render formats like floppy disks or old word-processor fi...

                Asummary of  using and reusing data Today, data curators dive into the heart of modern research ecosystems to explore a phase where scientific investments truly yield continuous, long-term value, using and reusing data. Within the broader research data lifecycle, data curation serves as the bedrock that transforms raw information into high-quality, sustainable digital assets. However, the true magic happens during the ultimate stage of this cycle the reuse phase. By ensuring data remains accessible to designated users on a day-to-day basis whether through openly published information or secured via robust access controls we open the door to endless collaboration. As highlighted by Yoon (2017), this phase allows independent secondary researchers to discover, access, and actively apply existing datasets to address fresh research questions or validate previous scientific discoveries. By systematically recycling verified scientifi...

  Data Storage Digital curation is the continuous process of managing, preserving, and adding value to digital assets throughout their lifecycle (Harvey & Bastian, 2020). A critical phase within this lifecycle is data storage, which involves maintaining digital objects in a secure, stable, and retrievable environment (Digital Curation Centre, 2021). According to Higgins (2018), proper storage ensures data integrity, prevents unauthorised access, and mitigates the risk of long-term bit rot. Organisations and individuals must align their storage practices with established international standards, such as ISO 14721, to guarantee that information remains accessible and authentic over time (International Organization for Standardisation 2012). Types of data storage, challenges and solutions To balance performance and budget, modern organizations deploy block, object, and file storage architectures (El-Haddad et al., 2022). High-performance block such as storage Amazon Elastic Bloc...

  SELECTION AND APPRAISAL OF DATA. Introduction Selection and appraisal serve as the foundational gateway within the digital curation lifecycle, directly dictating which data assets merit long-term preservation infrastructure. The rapid expansion of information generation renders the preservation of all digital assets financially and operationally impossible (Higgins, 2018; Whyte & Wilson, 2010). Digital curation systematically mitigates this information overload by employing objective criteria to separate transitory data from materials with enduring secondary research value (Lee & Tibbo, 2021). Consequently, appraisal functions not merely as a passive storage filter, but as an active workflow ensuring that limited organizational resources support authentic, accessible, and high-value historical records (Madu & Enyinnah, 2021; Niu, 2016). Establishing Policy and Compliance Safeguards The first phase of appraisal requires establishing formal institutional guidelines...

Welcome to My Blog Hello, I am Edith Hope Chavula. In today’s world, data is everywhere. However, knowing how to collect it properly and where to store it safely is the real challenge. I have started this blog to share clear and useful information on data collection and repositories. My goal is to help you understand how to gather high-quality information and use the best systems to keep it organised and accessible. Whether you are a student, a researcher, or just curious about data, I hope you find these posts helpful. Thank you for joining me on this journey! Examples of pictures for data collection and repositories Introduction In the contemporary digital landscape, the systematic storage of information is a prerequisite for organisational efficiency and continuity. For institutions such as universities or corporate entities, the ability to effectively capture and house data determines their operational success. This summary examines the mechanisms of data collection and ...
