CEDAR OnDemand

CEDAR OnDemand injects ontology-based metadata into HTML web submission forms to standardize metadata for biomedical data repositories, improving interoperability, discoverability, and reusability of experimental datasets.

Key Features:

• Ontology-Based Metadata Entry: Uses the National Center for Biomedical Ontology (NCBO) BioPortal to enable metadata entry with standardized ontology terms for consistent scientific terminologies.
• Automatic Ontology Recommendation: Analyzes HTML page contents to identify text input fields and recommends ontologies via the NCBO ontology recommender system using field labels and a predefined ontology list.
• Field-Specific Ontology Control: Associates specific ontologies with individual metadata fields to guide standardized entries aligned with established scientific vocabularies.
• Broad Applicability: Operates on any web form structured in HTML, enabling application across diverse biomedical data repositories.
• Enhanced Data Reusability and Discoverability: Promotes standardized ontology use to improve dataset discoverability, reuse, and integration across studies.

Scientific Applications:

• FAIR Data Stewardship: Supports the FAIR (Findable, Accessible, Interoperable, Reusable) principles by improving the discoverability and interoperability of biomedical metadata.
• Repository Metadata Standardization: Standardizes metadata submission in biomedical data repositories to facilitate cross-study integration and aggregated analyses.
• Reproducibility and Data Sharing: Enhances reproducibility and data sharing by ensuring experimental datasets are annotated with consistent ontology terms.

Methodology:

Automatically identifies input fields within HTML web forms and recommends relevant ontologies by analyzing field labels and consulting a predefined ontology list using the NCBO ontology recommender system and the National Center for Biomedical Ontology (NCBO) BioPortal.
