Overview – Building A Foldda Solution

Foldda solution is built using Windows folders, thus the process is primarily cut-n-paste, drag-n-drop, etc.

The Mighty HL7 Filter

Using Foldda Expression for identifying data-elements, and Regular Expression for pattern-matching, the HL7Filter is extremely powerful yet the the most easy to use.

Functions

Functions are used for transforming CSV and HL7 data element’s string value, to a new value or to a different format.

CONCAT Function

Concatenating multiple source string values into one.

PRINT Function

Printing multiple source string values to the node’s log, for debugging or for creating alerts.

FORMAT-DATETIME Function

Converts a date-time string value from one format to another, with the option to supply a default value if the conversion is unsuccessful.

IF-MATCH Function

This function matches a data element’s value to a regular expression pattern, and returns one of the two specified values depending on the pattern-matching result.
