SELECTION AND APPRAISAL OF DATA

Digital Curation Cycle
Digital Curation Life Cycle Diagram

INTRODUCTION

The National Archives and Records Administration of the United States of America (NARA) (2020) has defined appraisal as the process of determining the value of records to determine the preservation period of the resource. The value can be temporal or permanent. It can also be administrative, legal, research or historical. Despite an explosion in generation of information, Yeo (2018) envisioned a future where all records were to be preserved for eternity as an aftermath of digital curation reality. Nonetheless, Sucha-xaya (2024) argues that there is a need to appraise records and archives to ensure efficient and effective records and archives management whilst offering effortless search and retrieval regimes of the preserved resources. It should be noted that appraisal is conducted during the inception and life of borne resources. Review of the appraised resources can be conducted to weed those resources which no-longer possess value for preservation or to ascertain the currency of the file format for migration if necessary to ensure continued access of the preserved resources (Niu, 2014).

METHODS OF SELECTING RESOURCES

There are three methods which can be used for selecting resources for curation. The first one is Statistical Sampling Method. The method involves sampling to select resources for curation. Two kinds of sampling can be used to select resources for digital curation. The first one is Systemic Sampling that selects every nth item from a population and the second one is random sampling that selects items from a population with equal probability regardless of their values. The second method is Risk Analysis. The method involves assessment of the kinds of risks that could possibly happen to digital resources, as well as the probability and consequence of each risk. Commonly mentioned risks during selection processes include risk of obsolescence of file format and storage media, risk of loss caused by not preserving the digital resources and by storing resources in an unsafe area. The third method for selection of resources for digital curation is appraisal which involves ascertaining the value of resources that are to be considered for digital curation.

APPRAISAL ASPECTS

Appraisal has got three main aspects. One of such aspects is Objects of Appraisal. The objects include context of resources qualifying for curation also known as macro-appraisal (Shepherd & Yeo, 2003); the appraisal of the resources also referred to as micro-appraisal which looks at content, physical conditions and technical characteristics of the resources with an eye on curation feasibility and cost; significant properties of the resources; metadata and documentation (Niu, 2014).

The second appraisal aspect is Appraisal Criteria which has such evaluation factors as mission alignment, value of digital resources, cost and feasibility of the resources to be part of a repository despite being resources of value (Niu, 2014). 


The final appraisal aspect is Curators Decisions which involves deciding on resources to be included for curation, retention period of curated resources, decommissioning of resources from curation after reviews and format migration for perpetual access of curated resources whenever necessary (Niu, 2014).

DATA COLLECTION AND REPOSITORY


DATA COLLECTION

Kumar (2019) has defined Data Collection as a logical procedure of gathering data for supporting analysis and decision making. It involves accumulating data about a specific subject of interest for comparisons and decision making. Data is the smallest unit of information that does not make sense on its own (Bawden & Robinson, 2015). It must be processed to make sense for analysis and decision making. Several techniques can be used to gather data. The techniques include structured or unstructured observations; face to face or virtual interviews which might involve structured, semi structured or unstructured questions; paper based or online forms questionnaires and surveys; focus group discussions; case studies; document analysis and experiments (Cresswell, 2018).  The collected data has to be accurate, complete and from trusted sources to qualify as a productive resource for decision makers and analysts.


REPOSITORY

Repositories become quite handy in handling collected data. A repository is a central location for managing, preserving, discovering, sharing and reusing collected data (Erima & Maseh, 2025). Repository ensures that collected data abides by the Open Archival principles which are being Findable, Accessible, Interoperability and Reusability (FAIR). The repository ensures increased donor trust, visibility and productivity of collected data preserved in the repository (Lee & Stvilia, 2017). There are two main types of repositories. The first one is the Institutional Repository which captures and preserves data for one single institution (Lee & Stvilia, 2017). An example would be a repository owned by Mzuzu University. Disciplinary Repository is the second one. This kind of repository focuses on a particular subject of interest (Sharma, 2022). An example of such a repository would be Information Science Repository. There are several software which are used to build repositories. Some of the repository software include Ivenio, Roar, Fedora, DSpace, Greenstone and EPrints.

RELATIONSHIP BETWEEN DATA COLLECTION AND REPOSITORY

Data collection and repository are inseparable because of the values they bring to each other. Here are some of the bonding values of the two concepts:

1.      Data Collection Feeds the Repository

Data collection provides for the content to be kept into the database. Without the data, the repository would be empty. Data collection provides the input for the repository.

2.      Repository Organizes Collected Data

The repository provides an interface for the collected data to be classified and indexed using data about data so that it should be discoverable whenever need arises.

3.      Repository Drives Data Preservation

The repository provides long term storage for evidential and historical data.

4.      Repository Provides Data Access

Repository enables data access by providing an interface for the stored data to be retrieved, shared and analyzed.

5.      Repository Provides Data Trustworthiness

Repository ensures there is preserved contextuality of preserved data by ensuring access security and audit trials to the stored data.

SUCCESSFUL DATA COLLECTION AND REPOSITORY REGIME

Chawinga and Zinn (2021) argue that positive attitudes, availability of skills for data collection and maintenance of a repository and its infrastructure and availability of policies for Open Access would facility successful regimes of Data Collection and Repository at a particular time and space.

CONCLUSION

Data Collection and Repository provide an intersection of effective and efficient information management. The intersection of the two concepts ensures efficient and effective data retrieval and trustworthiness.
