Several value sets in the Citation Resource can have codes added based on recent implementations, including:

for CitationArtifactClassifier - add codes for Clinical Decision Support Artifact, Model, Interactive Form, Terminology, PseudoCode, and Standard - actual examples from MCBK efforts and from creating citations for the FHIR specification

for CitedArtifactStatusType - add accepted, approved, and created

for TitleType - add official - use needed for ClinicalTrials.gov

for JournalIssueMedium-- CHANGE value set name to CitedMedium — add offline-digital-storage, print-without-issue, offline-digital-storage-without-issue (to the 3 existing codes of internet, print, and internet-without-issue)

for articleUrlType - add code-repository, computable-resource, version, restricted, and file-directory; REMOVE abstract-version, full-text-version, pdf-version, json-version, xml-version, and supplementary-file-directory; ALSO CHANGE Citation.citedArtifact.webLocation.type to 0..* cardinality - use case is a type="compressed-file" could be coupled with type="computable-resource" as both types are important to denote

for ContributorSummaryType - complete list to cover author-string, contributorship-list, contributorship-statement, acknowledgement-list, acknowledgement-statement

for CitedArtifactClassificationType – add code "coverage", display "Coverage" and definition "The spatial or temporal topic of the resource, spatial applicability of the resource, or jurisdiction under which the resource is relevant"
