1. A method, comprising: accessing a standardized language tag repository to identify changes in repository language tags; searching records of a data source stored in a memory where one or more of the records are categorized using language tags as metadata attributes to identify language tags present in the records of the data source; determining whether the language tags present in the records of the data source are inconsistent with the repository language tags; responsive to determining that the language tags present in the records of the data source are inconsistent with the repository language tags, determining a language tag update policy for the data source; responsive to determining that the language tag update policy indicates preserving an integrity of a first set of the records of the data source, creating a reference metadata based on the repository language tags; linking the reference metadata to the respective first set of records having inconsistent language tag metadata attributes while maintaining the first set of data records intact with the inconsistent language tag metadata attributes; and performing a language tag update process for a second set of the records having inconsistent language tag metadata attributes according to the language tag update policy to replace the inconsistent language tag metadata attributes based on the repository language tags.
