298 | SNOMED CT Release Format 1 (RF1) Guide July 2012 If the ContentSubType includes more than one component (e.g. document status and a language code), the language code must be the last component in theContentSubType element and should be preceded by a hyphen ("-") placed before the language code. 3.4.5. Country|Namespace element 3.4.5.1. Description The Country | Namespace element of the filename helps to identify the organization responsible for developing and maintaining the file. Its format is 2-10 alphanumeric characters consisting of 0, 2 or 3 upper-case letters followed by 0 or 7 digits. 3.4.5.2. Rules The following rules apply to the content of this element: • Letters, if present, are either the ISO -3166 2-character country code for an IHTSDO Member country or "INT" for files that are part of the IHTSDO's International Release of SNOMED CT; • Digits, if present, are a SNOMED CT Namespace Identifier. Valid combinations are: • 2 characters only - the file is part of a Member National Release, but not part of a specific Namespace - this combination is not valid for Data Files ("sct ","der" or "res"); • 3 characters only ("INT") - the file is part of the IHTSDO International Release and belongs to the International Namespace; • 2 characters and 7 digits - the file is part of a Member National Release and belongs to the specified Namespace; • 3 characters and 7 digits - the file is an optional part of the IHTSDO International Release and belongs to the specified Namespace; or; • 7 digits only - the file has been developed and released by a 3rd party, identified by the specified Namespace. 3.4.6. VersionDate element 3.4.6.1. Description The VersionDate element of the filename identifies the SNOMED CT version with which the file is intended to be used. Its format is an 8-digit number in the pattern "YYYYMMDD", in compliance with the ISO 8601 standard. 3.4.6.2. Rules The following rules apply to the content of this element: • For Data Files("sct","der" or "res"),and for Documentation (" doc") with a status tag value of "Current", the value of this element should always be the same as the SNOMED CT version date with which the file is associated. • For other file types, the VersionDate element will identify the (past) date of the SNOMED CT release for which the file was intended. A file distributed with a past version date has not been updated to reflect changes to SNOMED CT since that date, nor has it been validated as correct or appropriate for current use. © 2002-2012 International Health Terminology Standards Development Organisation CVR #: 30363434
VersionDate refers to the official, published date of a SNOMED CT International Release, or of the National Release of an IHTSDO Member country, and may not always correspond to the actual date of distribution of any particular release. 3.4.7. Extension element Formats | 299 The extension element of the filename identifies the file format (encoding convention) of the file, such as "txt ", "pdf" or "zip". It has a format of 1-4 alphanumeric characters. © 2002-2012 International Health Terminology Standards Development Organisation CVR #: 30363434
