University of Hong Kong Repository: HKU Scholars Hub
Depositing your research outputs in HKU Scholars Hub, the official institutional repository of University of Hong Kong, is a critical pathway to achieving green open access and satisfying funder mandates in Hong Kong. This guide outlines the submission and curation workflows required to preserve and disseminate your academic publications and associated datasets in accordance with DSpace standards.
1. Institutional Archiving & Preservation Strategy
The technical architecture of HKU Scholars Hub relies on the DSpace repository engine, configured to host and index peer-reviewed articles and research data for University of Hong Kong. This industry-standard institutional repository software streamlines indexing in Google Scholar and OpenAIRE.
The university library's digital preservation strategies at University of Hong Kong are designed to prevent technological obsolescence. By encoding preservation metadata (such as PREMIS elements) and maintaining master files in uncompressed archival formats, HKU Scholars Hub guarantees that publications and data remain renderable in Hong Kong. This framework defines the structural difference between a simple depository vs repository model, where HKU Scholars Hub actively manages integrity and accessibility rather than merely serving as static storage.
Verified Institutional Impact Metrics
Based on independent indexing data from the open-science catalog OpenAlex, University of Hong Kong has recorded a cumulative corpus of 228,747 publications which have received over 21,869,651 citations globally. This volume highlights the critical role of HKU Scholars Hub in providing open access to a massive stream of global knowledge. With an institutional h-index of 1162 and a two-year mean citedness score of 4.88, submissions deposited here carry a highly visible citation trajectory.
All submissions to HKU Scholars Hub undergo systematic verification by the university library team. This ensures compliance with publisher embargoes, rights-retention policies, and copyright licenses (predominantly Creative Commons CC-BY or CC-BY-NC).
2. Metadata Mapping: Simple Dublin Core Alignment
The indexing backbone of HKU Scholars Hub is strictly configured around the Dublin Core metadata standard to catalog outputs from University of Hong Kong. Each deposit record is structured according to the Dublin Core metadata element set, ensuring that the schema incorporates standard Dublin Core metadata terms for rapid cross-archive mapping inside Hong Kong.
Discoverability of HKU Scholars Hub's assets is highly dependent on records cleanliness. The ingestion portal of University of Hong Kong routes every record through an automated metadata cleaner to flag inconsistent values. Library curators then apply a comprehensive metadata scrubber to remove duplicate tags, parse affiliations, and link author entries to their respective ORCID profiles to satisfy standards in Hong Kong.
To align with international standards, publications at University of Hong Kong are catalogued using the Library of Congress Subject Headings (LCSH), establishing a highly structured controlled vocabulary for HKU Scholars Hub. This systematic approach to thesaurus construction and metadata indexing enables robust cross-disciplinary discovery in Hong Kong. Furthermore, records are mapped to the MARC21 format for library catalog sharing.
| Dublin Core Element | Preserved Value / Standard | Function & Mapping |
|---|---|---|
| dc.title | Full Article / Book Title | Main headline as registered in the publication record |
| dc.creator | Author(s) names & ORCID iD | Linked explicitly to the author's CRediT contribution roles |
| dc.publisher | University of Hong Kong Library Services | The entity making the resource accessible in Hong Kong |
| dc.identifier | Handles / persistent URLs | Local institutional handle mapping to OAI-PMH networks |
