Utility function to import data to a MySQL database from Annotation Hub
ahToMySQL(ah, annotations = list(), ...)
ah |
[AnnotationHub()] object with records to add to database. |
annotations |
A named list of lists (key/value pairs). Keys must be the AH ID for the corresponding record and the value is a named list representing an annotation. An annotation is automatically inferred by the record's metadata. Any annotation that is passed for a particular record is concatenated to its inferred annotation. If the annotation has a subtype column, it is used to name the data object being added to the db, otherwise the record's tags is used. |
