Discovering linked data collections through a new national metadata platform

Area of Science:

• Health research infrastructure
• Data management
• Linked data research

Background:

• Metadata is vital for health research infrastructure.
• Challenges exist in finding and accessing metadata for multiple data collections due to a diverse data custodian landscape in Australia.
• This hinders linked data researchers, making information retrieval arduous and time-consuming.

Purpose of the Study:

• To develop a metadata platform to improve the discoverability and evaluation of Australian data collections for linked data research.
• To address challenges faced by researchers in accessing and assessing relevant metadata.
• To standardize metadata presentation nationally.

Main Methods:

• A three-phase project: scoping, national consultation, and platform build/implementation.
• Involved understanding current metadata practices and best practices.
• Developed a high-fidelity prototype through user consultations, prototyping, and testing cycles.

Main Results:

• Expert interviews confirmed abundant but inaccessible metadata.
• Researchers identified needs for standardized metadata and a centralized platform for enhanced discoverability.
• Key features included search, browse, filter capabilities, data item lists, standardized formats, sample data, and FAQs.

Conclusions:

• The Population Health Research Network developed a metadata platform to aid researchers in evaluating Australian data collections for linked data projects.
• The platform standardizes metadata presentation nationally, improving quality, readability, and accessibility.
• This leads to time savings and enhanced quality of linked data applications.
