  This technical report presents an evaluation of the ontology annotations in
the metadata of a subset of entries of MetaboLights, a database for
Metabolomics experiments and derived information. The work includes a manual
analysis of the entries and a comprehensive qualitative evaluation of their
annotations, together with the evaluation guide and its rationale, that was
defined and followed. The approach was also implemented as a software script
that given a MetaboLights entry returns a quantitative evaluation of the
quality of its annotations (available on request).
