The Challenge: A Rare Intersection

The report highlights a core difficulty: finding a single dataset that simultaneously meets all criteria for advanced web application development. The ideal resource must exist at the rare intersection of raw multimodal data and permissive licensing.

While no single dataset is perfect, several candidates offer significant value. Click on a card below to explore a summary of its key characteristics, strengths, and limitations as identified in the source report.

A Comparative Deep Dive

Visualizing the data landscape reveals key trends and gaps. The following charts compare the top candidates on two critical axes: the availability of specific sensor data and the restrictiveness of their licenses for web application development.

Sensor Signal Availability

This chart highlights the "EEG Gap" — while ECG and PPG are common in clinical datasets, linkable raw EEG is notably rare.

Licensing Barriers for Web Apps

A major finding is that data utility is often limited by licensing. This chart scores datasets on their suitability for web applications, where a higher score means more restrictions.

Recommended Strategic Pathway

The report concludes with a pragmatic approach for developers. This flowchart visualizes the recommended decision-making process for selecting and integrating datasets, acknowledging the existing gaps and challenges.

START: Define Core Application Needs
Is Raw ECG/PPG + Clinical Context the Priority?

YES: Primary Path

Prioritize MIMIC-IV. It has the strongest combination of raw ECG/PPG, linkable imaging (CXR), and deep clinical context.

Is Raw EEG a Day-1 Must-Have?

ACTION

Acknowledge the EEG gap in MIMIC-IV. Plan to augment with a specialized EEG dataset from OpenNeuro. This requires a complex data fusion strategy.

Is Commercial Use Foreseen?

ACTION

Carefully review the Data Use Agreements (DUA) for MIMIC-IV. Avoid "Research Use Only" licenses like EchoNet-Dynamic. Engage legal counsel on compliance.

Future Outlook

While challenging today, the trend towards open, integrated data is accelerating. The report concludes on an optimistic note, anticipating more comprehensive, FAIR (Findable, Accessible, Interoperable, Reusable) datasets in the near future.
