<Li> Metadata (elements of) </Li> <Li> Point - in - time versus post-hoc </Li> <P> Australian medical research pioneered the definition of metadata for applications in health care . That approach offers the first recognized attempt to adhere to international standards in medical sciences instead of defining a proprietary standard under the World Health Organization (WHO) umbrella . The medical community yet did not approve the need to follow metadata standards despite research that supported these standards . </P> <P> Research studies in the fields of biomedicine and molecular biology frequently yield large quantities of data, including results of genome or meta - genome sequencing, proteomics data, and even notes or plans created during the course of research itself . Each data type involves its own variety of metadata and the processes necessary to produce these metadata . General metadata standards, such as ISA - Tab, allow researchers to create and exchange experimental metadata in consistent formats . Specific experimental approaches frequently have their own metadata standards and systems: metadata standards for mass spectrometry include mzML and SPLASH, while XML - based standard such as PDBML and SRA XML serve as standards for macromolecular structure and sequencing data, respectively . </P>
