Extensible biosignal metadata a model for physiological time-series data

Abstract

The domain specific nature of biosignal storage formats, along with the lack of support for metadata in generalpurpose biosignal libraries, has hampered the easy interchange of biosignals between disciplines and their integration with physiological modelling software. Extensible Biosignal Metadata (XBM) is introduced as a standard framework to facilitate the sharing of information between and within research groups for both experimentalists and modellers; to help establish more web-accessible biosignal repositories; and, by using semantic web technologies, to result in the discovery of knowledge by automated reasoning systems.

StorageBIT - A Metadata-aware, Extensible, Semantic and Hierarchical Database for Biosignals

“…More recently, the focus has been given to semantic approaches (see, for example, (Brooks et al, 2011), (Kokkinaki et al, 2008), and (Brooks, 2009)), where, in addition to the core biosignal data, contextual information is included, such as patient and acquisition procedure information, enabling the integration of disparate and heterogeneous sources of medical information and facilitating their query and retrieval.…”

“…Some common metadata fields can be seen in Figure 1. The use of metadata allows for knowledge to be processed computationally in a comparable way to numeric data (Brooks, 2009); 6) Multi-modality: The capability to store various signal types in a single container struc- ture. These signals may be of different nature (e.g.…”

Minimum Information about a Cardiac Electrophysiology Experiment (MICEE): Standardised reporting for model reproducibility, interoperability, and data sharing

“…In the near future, this will need to be followed by (ii) and (iii), to ensure efficient automated search processes. For this, an XML-based standard for time varying data will be useful, such as is being developed through the BioSignal Markup Language (BioSignalML) (Brooks, 2009). Ultimately, further development will require a commitment from national, regional, and/or private funding agencies, and while resources are always in short supply, cost-benefit considerations suggest that this would be in the best interest of all involved.…”
