Vivodata

Vivodata is a term used in some scientific and data-science contexts to describe data that originates from living organisms in vivo. It encompasses time-dependent measurements collected in real time or longitudinally, including physiological signals, molecular profiles from in vivo samples, imaging data acquired in living subjects, and behavioral or ecological observations. It is distinguished from in vitro or ex vivo data, which are collected outside the living organism.

Origin and scope: The term is not tied to a single formal standard; it arose in interdisciplinary literature as researchers sought to emphasize provenance from living systems and to support integration of multimodal data. Definitions vary by field, with some focusing on clinical and physiological monitoring, others on in vivo omics and imaging.

Data types and formats: Vivodata spans diverse modalities such as time-series physiological data (heart rate, blood pressure), in vivo metabolomics and transcriptomics, imaging datasets (functional MRI, PET), and behavioral or ecological tracking. Metadata and provenance information are central for interpretability, with researchers typically aligning data to domain standards where possible (for imaging, DICOM; for omics, MIAME or MINSEQ); but there is no universal vivodata standard.

Applications: In biomedical research, vivodata supports disease modeling, pharmacodynamics, and translational studies; in healthcare, it underpins patient monitoring and personalized medicine; in ecology, it informs studies of animal behavior and population dynamics.

Challenges and ethics: Data heterogeneity, temporal alignment, and quality control are major challenges. Privacy, consent, and the ethical use of living subjects are critical considerations, especially for human data.
