Change term - countryCode

[tucotuco]

Term change

• Submitter: John Wieczorek (on behalf of the Biodiversity Data Quality Task Group TG2)
• Efficacy Justification (why is this change necessary?): To validate the use of user-defined ISO codes 'ZZ' and 'XZ' for "unknown" and "High Seas" respectively. 'XZ' is the code recommended for high seas by the UN/LOCODE. See BDQ issues 20, 21, 50, 51, 62, 98.
• Demand Justification (if the change is semantic in nature, name at least two organizations that independently need this term): If only standard two-letter ISO codes are used, there is no accepted way to designate that a first level administrative division given in dwc:country is interpretable as being on the high seas (beyond national jurisdiction), or to distinguish that from explicitly unknown or unambiguously interpretable to a single country code. This proposal provides for a standard way to designate the high seas and to designate (separately) locations that can not be assigned to a single dwc:countryCode.
• Stability Justification (what concerns are there that this might affect existing implementations?): This is an added capability that does not change the validity of previously valid values for the term.
• Implications for dwciri: namespace (does this change affect a dwciri term version)?: None

Proposed attributes of the new term version (Please put actual changes to be implemented in bold and strikethrough):

• Term name (in lowerCamelCase for properties, UpperCamelCase for classes): countryCode
• Term label (English, not normative): Country Code
• Organized in Class (e.g., Occurrence, Event, Location, Taxon): dcterms:Location
• Definition of the term (normative): The standard code for the country in which the dcterms:Location occurs.
• Usage comments (recommendations regarding content, etc., not normative): Recommended best practice is to use an ISO 3166-1-alpha-2 country code , or 'ZZ' (for an unknown location or a location unassignable to a single country code), or 'XZ' (for the high seas beyond national jurisdictions). Recommended best practice is to leave this field blank if the dcterms:Location spans multiple entities at this administrative level or if the dcterms:Location might be in one or another of multiple possible entities at this level. Multiplicity and uncertainty of the geographic entity can be captured either in the term dwc:higherGeography or in the term dwc:locality, or both.
• Examples (not normative): AR; SV; XZ; ZZ
• Refines (identifier of the broader term this term refines; normative):
• Replaces (identifier of the existing term that would be deprecated and replaced by this term; normative): http://rs.tdwg.org/dwc/terms/version/countryCode-2023-06-28
• ABCD 2.06 (XPATH of the equivalent term in ABCD or EFG; not normative): DataSets/DataSet/Units/Unit/Gathering/Country/ISO3166Code
