The PolyU Research Data Repository (Beta)

Digital Object Identifier (DOI)

Data repositories usually assign a persistent identifier to the deposited data which improves the discoverability of the data. Digital Object identifier (DOI) is one of the persistent identifiers that permanently points to a webpage, a dataset, or other digital objects even the location of the object changed. 

PolyU Research Data Repository provides free DOI assignment services to PolyU researchers who publish their datasets in the repository. Re-users will then cite your data providing the DOI for readers to refer to. After the data files are published, you can find the DOI assigned to your data:

Data Citation

Research Data is an independent scholarly work that is citable. When a dataset is uploaded to our repository, anyone reusing the data can export the citation in formats for reference management software at ease.

Proper citation is required when any research data is reused. A citation helps to acknowledge the creator and help the readers locate the source of the information.

Format and elements of a data citation vary among disciplines. The recommended elements in a data citation include:

• Author: The creator(s) of the data set.
• Publication Year: The date the dataset was made available.
• Title: The name of the cited dataset.
• Publisher/Distributor: the organization hosting the data.
• Version/Edition (if any)
• Resource type: e.g. dataset, data file and codebook, database.
• Persistent URL/identifier: e.g. DOI, Handle, ARK, PURL.
