Appendix C - Dialect Aliases

This appendix provides a list of example aliases that may be used to specify a particular dialect in an ECL filter constraint. Please refer to the 'Dialect Filter' section on 6.8 Description Filters for more information on how these dialect aliases are used in ECL.

All dialect aliases should follow the ABNF syntax shown below. This format is designed to be compatible with BCP-47 (Internet Best Current Practice Specification), which ensures alignment with a range of other specifications - e.g. HTTP "accept-language" headers, and the HL7 FHIR "designation.language" data element.

dialectAlias = ( language [ "-" script ] [ "-" region ] [ "-" privateuse ] ) / privateuse

language = alpha alpha ; ISO 639-1 code (List of codes)

script = alpha alpha alpha alpha ; ISO 15924 code (List of codes)

region = alpha alpha ; ISO 3166-1 code (List of codes)

privateuse = "x" 1*("-" 1*8(alpha / digit) ) ; the clinical scope or context of use

The table below lists the valid 'dialect' filter values and their equivalent 'dialectId' filter values, for a selection of known language reference sets. To request the addition of a new dialect alias, please use the 'Feedback' button on the bottom of this page.
