Document related to a given data exchange schema or model, it describes all the associations between the specific schema section and the appropriate CV terms. Comprehensive list of CVs that are required by a schema or model. Description of a CV or ontology resource. Comprehensive list of associations between a model and CVs. Single mapping rule between a specific elements of the model and to controlled vocabularies listed on the CvTerm element. Name of the PSI data exchange schema, e.g. mzData, GelML, MIF. URI of the data exchange schema Version number of the model supported by the CvMapping file. One or more terms from a CVsource that are allowed to be associated with the given element of the model. Element scope in the schema within which the non repeatable (isRepeatable = FALSE) condition applies. Boolean operator describing the combination logic of multiple CvTerm elements associated with the same CvMappingRule. The requirement level indicated, when the XML element exists in the instance data file, if the association with CV terms is optional (MAY), recommended (SHOULD) or mandatory (MUST). Name of this rule (can be used for reporting of errors) Unique identifier of the rule in this mapping file. Internal reference (e.g. namespace abbreviation) to a term source file as defined in a CvReference element. CV term accession number as in the CV file. Boolean to set whether the check is done on the termName (TRUE) or on the termAccession (FALSE and default). This attribute indicates whether the term itself can be used to annotate data (TRUE) or not (FALSE). This latter case may happen when a term, parent of valid terms for annotation, is mentioned to keep the mapping concise. This attribute indicates whether the children of the described term are allowed to annotate data (TRUE) or not (FALSE). Value is 'True' when a term can be repeated in the same instance of the associated XML element. Short label for the CV or namespace, this should correspond to a cvIdentifier attribute of CvTerm Full descriptive name for the CV.
