Research Data Management

Data Creation and Collection

"Information in digital, computer-readable format or paper-based that is collected, generated or obtained during the course of or as a result of undertaking research, which is subsequently used by the Researcher as a basis for making calculations or drawing conclusions to develop, support or revise theories, practices and findings."

See Research Data Management Policy at NUI Galway

Research Data Lifecycle

"The notion of a data lifecycle is one that has gained popularity as the culture of data sharing becomes part of our everyday research language. The data lifecyle extends the typical research cycle" 

Corti, Louise, Van den Eynden, Veerle, Bishop, Libby, & Woolard, Matthew. (2014). Managing and sharing research data: a guide to good practice. London: Sage. p.17

Sensible file names and a well-organised folder structures makes it easier to find and keep track of data files. Links to relevant advice and resources provided by the UK Data Service are outlined below.

Documentation is the contextual and explanatory information required to make sense of the dataset. It is a users' guide to your data making it understandable, verifiable and reusable.

Document your data so that ...

  • You remember the details later
  • Others can understand your research
  • Your findings can be verified
  • Your results can be replicated
  •  Risk of misinterpretation is avoided
  • Your data can be archived for access and re-use

Research data should be documented at various levels

Study level

  • Describes the research project, the data creation processes, rights and general contexts. Good study level data should include information about research design and context, data collection methods, structure of data files, secondary data sources used, data validation procedures, conditions of use.

Data level

  • Describes how all the files (or tables in a database) that make up the dataset relate to each other; what format are they are in; whether they supercede or are superceded by previous files. A readme.txt file is the classic way of accounting for all the files and folders in a project.

Examples of data documentation

  • Database schema
  • Information about equipment settings and instrument calibration
  • Laboratory notebooks and experimental protocols
  • Methodology reports
  • Provenance information about sources of derived or digitised data
  • Questionnaires, codebooks, data dictionaries
  • Software syntax and output files

Advice about good practice relating to documentation and metadata is available from the UK Data Service.

A Guide for Researchers from OpenAIRE: Electronic Lab Notebooks - should you go “e”?

Metadata is similar to Documentation (see related tab) but is more structured, conforms to set standards and is machine readable. It is required to facilitate archiving, discovery and citation of the dataset.

Metadata is a formal structured description of a dataset, used by archives to create catalogue records. It is structured, conforms to set standards and is machine readable.There are three categories of metadata:

Descriptive metadata includes author, title, keywords and abstract and enable users to find resources online.

Administrative metadata includes information about when and how a resource was created as well as file type, technical information and access rights.

Structural metadata provides information about the relationship between the parts that make up a compound object e.g.relating articles, issues and volumes of serial publications, or the pages and chapters of a book.

Metadata describes the content, quality, condition, and other characteristics of a dataset. It enables data to be preserved, minimizes duplication of effort in the collection of expensive digital data and fosters the sharing of digital data resources. 

  • Who created the data?
  • What is the content of the data?
  • When were the data created?
  • Where is the data geographically?
  • How were the data developed?
  • Why were the data developed?

Why is metadata essential?

Metadata enables data developers to:

  • Avoid data duplication because they check if data already exists
  • Share reliable information about a dataset by creating metadata for it
  • Reuse a dataset with confidence about its origins and quality as well as having valuable information about it
  • Publicize the data they have created by making the metadata available in repositories
  • Cite their datasets and increase the visibility of the data.

Metadata enables user to:

  • Search for and get access to data from a variety of sources
  • Restrict searches to a geographic regions
  • Determine whether the data will be applicable for use in a particular study
  • Acquire a dataset
  • Know restrictions on how a dataset use

Metadata enables organizations to:​

  • Safeguard their investment in their data by retaining information about how it was collected, processed, quality controlled, used and restricted
  • Create a permanent record of the dataset which is critical institutional memory 
  • Ensure that datasets “live on” for the organization after researchers leave or retire
  • Re-use dataset in another research project if appropriate and future researchers will know how the datset was created
  • Advertise its research and enable new partnerships and collaborations by data sharing

Essential fields

Title: Name of dataset or research project that produced it. (Include both if applicable.)

Creator(s): Names and addresses of the group that created the data.

Identifier: Unique identifier or number that is used to identify the data. This could be an internal project number or code to reference the data.

Abstract/Description: A brief synopsis of the project or data that another researcher can review quickly to see the relevance of the project to what they are seeking.

Dates: All the dates associated with the project. The most important is probably the release date of the data, but you'll eventually want to include:

  • start and end date of the project
  • time period covered by the data or project
  • maintenance cycle of the data
  • update schedule of the data
  • any other important dates that will help document the process and aid in preservation

Rights: Any known intellectual property rights held for the data or project.

Recommended fields

Variable List: List of variables in the data files, when applicable.

Code Lists: Explanation of codes or abbreviations used in the file names, variables of the data, or the project over all that will help the user understand the project. (e.g., "999" indicates a missing value in the data)

Versions: Date/time stamp for each file and use a separate identifier for each version.

Checksums: Used to test if your file has changed over time. (This will aid in the long term preservation of the data and help make it secure by tracking alterations.)

Related Materials: Links or location of materials that are related to the project. (e.g., articles, presentations, papers)

Citation: The recommended way to cite the data or the information needed.

What is a metadata standard?

A Standard provides a structure to describe data with:

  • Common terms for consistency between records
  • Common definitions for easier interpretation
  • Common language for ease of communication
  • Common structure to quickly locate information

Standards provide a uniform summary description of a dataset.

The Research Data Alliance Standards Directory contains widely used metadata standards in the Arts and Humanities, Engineering, Life Sciences, Physical Sciences and Mathematics, Social and behavioural Sciences and General Research Data.

The Digital Curation Centre provides links to information about discipline specific metadata standards, including profiles, tools to implement the standards, and use cases of data repositories currently implementing them.

Biosharing is an educational resource on inter-related data standards, databases and policies in the life, environmental and biomedical sciences.

The Data Documentation Initiative (DDI) is an international standard for describing the data produced by surveys and other observational methods in the social, behavioural, economic, and health sciences. DDI is a free standard that can be used to document and manage different stages in the research data lifecycle, such as conceptualization, collection, processing, distribution, discovery, and archiving. Documenting data with DDI facilitates understanding, interpretation, and use by people, software systems, and computer networks.

CEDAR (Center for Expanded Data Annotation) is a repository of community defined metadata templates.  and Retrieval. Its goal is to improve metadata and its use in the biomedical sciences. The CEDAR metadata tools can be used to create, annotate, analyze, validate and search metadata based on the fields and relations defined in the metadata templates.

  • Find datasets by using the Data Citation Index (available via the Web of Science) is an index to research data from repositories across disciplines and around the world. You can access it from the Library catalogue. It indexes data and provides links to repositories where it is stored. Click here for short tutorial on the Data Citation Index
  • Data repositories or archives allow researchers to upload and publish their data, thereby making the data available for other researchers to re-use. Similarly, a data archive allows users to deposit and publish data but will generally offer greater levels of curation to community standards, have specific guidelines on what data can be deposited and is more likely to offer long-term preservation as a service. Sometimes the terms data repositories and data archives are used interchangeably.

  • Data Journals
    • Data journals offer a platform for publication of "data articles" or "dataset papers" that are typically short articles providing a technical description of a dataset.
    • Some data journals also publish (i.e. host) the dataset themselves. Others link to datasets hosted on dedicated data repositories.
    • Conventional journals may link to datasets (e.g. Nature) or embed research data within the structure of the scientific article.

Note: Minimum requirements for the third-party hosting may be specified e.g. Geoscience Data Journal specifies that the host repository must be able to mint a DOI. New data journals that are peer reviewed and citable include Scientific Data (Nature) and the Geoscience Data Journal (Wiley).
