Definert av Produsenten av GEDCOM 5.5

Under Introduction:

Non-standard tags (see <NEW_TAG>) can be used within a GEDCOM transmission, provided that the first character is an underscore (for example _NUTAG). Non-standard tags should be used only when structured information cannot be represented using existing context. Using a Note field is a more universal way of transmitting genealogical data that does not fit into the standard GEDCOM structure. 

 

Under Chapter 2

NEW_TAG: = {Size=1:15} 

A user-defined tag that is contained in the GEDCOM current transmission. This tag must begin with an underscore (_) and should only be interpreted in the context of the sending system. 

 

Under Chapter 2

User-Defined Tags 

We do not encourage the use of user-defined GEDCOM tags. Applications requiring the use of non-standard tags should define them with a leading underscore so that they will not conflict with future GEDCOM standard tags. Systems that read user-defined tags must consider that they have meaning only with respect to a system contained in the HEAD.SOUR context.
