Minimum Data Set and Metadata for Active Vaccine Safety Surveillance: Systematic Review
Furthermore, metadata, which provides descriptive information about datasets—plays a key role in standardizing data classification, integration, and analysis across different surveillance systems [24]. Therefore, establishing a standardized MDS and metadata system is essential for optimizing AVSS, particularly in resource-limited settings.

Data Interoperability in COVID-19 Vaccine Trials: Methodological Approach in the VACCELERATE Project
Metadata items such as data format, data dictionary name, response type, item text, required field indicator, and review groups were compared for consistency and discrepancies. Once identified, the next step was to analyze the rationale behind the observed consistencies and discrepancies among the metadata items.

Emerging Domains for Measuring Health Care Delivery With Electronic Health Record Metadata
EHR use metadata (eg, audit logs, orders metadata, documentation and communication metadata, and patient encounters metadata) contain valuable details on the complex system in which health care is delivered, with early insights primarily focused on discrete action or time-based measures [8-15].

Following the FAIR principles, metadata is of foremost importance for the quality re-use of information. Metadata should ideally include references to international terminology codes that unambiguously represent each concept. Whenever possible, all CRF variables should be handled as close-ended questions. In case of measurement or observations, Logical Observation Identifiers Names and Codes (LOINC) should be used.

Exploring Metadata Catalogs in Health Care Data Ecosystems: Taxonomy Development Study
Metadata describe dataset attributes, such as source, format, structure, provenance, owner, access, or governance modalities [29]. Metadata catalogs act as “catalogues of data catalogues,” dedicated to enhancing discoverability, usability, and management of distributed datasets [30].

Toward Better Semantic Interoperability of Data Element Repositories in Medicine: Analysis Study
Metadata, essentially data about data, offers a solution to address such issues. Metadata can describe data, providing researchers with a comprehensive overview to aid understanding and application. Furthermore, it supports more precise retrieval and traceability. When data are accurately associated with metadata (such as “18” being linked to an individual’s total years of smoking), its semantics become much more straightforward.

Group 1 (“with or without”) labeled the CFPs with metadata in Phase 1 and without metadata in Phase 2. Group 2 (“without or with”) labeled the CFP in Phase 1 without metadata and with metadata in Phase 2. In Phase 2, the order of presentation for the same CFPs was scrambled for both groups (Figure 1). After labeling the test set images with and without metadata, the results of ICDR scores and the presence or absence of ME were recorded for each participant.

Finding data and knowledge or information about population health requires accurate and comprehensive documentation of metadata, often referred to as “data about data”; however, the best way to achieve this remains unclear [4]. Disease surveillance metadata encompass crucial details, including the diseases under surveillance, geographical areas covered, and variables measured, each with defined formats and explanations.

A crucial factor in advancing these objectives is the metadata acquired from the data transformation and integration process throughout the data life cycle. The field of biological research has already acknowledged the significance of metadata, as outlined in ISO norms such as ISO/CD 20961 [15] and ISO/TC 276/WG5 on data processing and integration [16]. ISO 20961, for example, specifies requirements for the consistent formatting and documentation of data and metadata.

Provenance assertions are a form of contextual metadata and can themselves become important records with their own provenance” [13].
W3 C provenance: is a family of specifications for provenance with a generic concept to express specific meta-information (or metadata) about data and its related artifacts.
