metricTypes	xs:string (required) options: AcademicCorporateCollaboration, AcademicCorporateCollaborationImpact, Collaboration, CitationCount, CitationsPerPublication, CollaborationImpact, CitedPublications, FieldWeightedCitationImpact, ScholarlyOutput, PublicationsInTopJournalPercentiles, OutputsInTopCitationPercentiles	This represents the types of metrics desired in the response. More than one can be specified. ex. metrics=Collaboration,CitationCount
yearRange	xs:string default: 5yrs options: 3yrs, 3yrsAndCurrent, 3yrsAndCurrentAndFuture, 5yrs, 5yrsAndCurrent, 5yrsAndCurrentAndFuture, 10yrs	The year range for which to calculate the metric values. For instance, if the current year is 2018, 3yrsAndCurrentAndFuture would be 2015-2019.
