This is the initial draft of the msi-nmr-ontology binned under webimported OBI and BFO classes. This is a primary discussion- and test-version to encourage nmr term development. As a secondary role this ontology serves as a testbed to evaluate the BFO top level ontology , modularization and the owl-import and referencing mechanism.The nmr ontology is developed by the ontology working group (http://msi-ontology.sourceforge.net/) of the msi-metabolomicssociety (msi-workgroups.sf.net).Keywords: NMR, nuclear magnetic resonance, metabolomics, metabolomics investigation, metabolomics experiment Important top level classes: NMR_instrument, NMR_instrument_configuration, NMR_parameter_set, NMR_vendor, NMR_software, data_processing_method, NMR_spectrum, NMR-data-set, NMR_probe Intended application: data annotation, reporting requirements usage: in development
