For this, an entire model based on C structs is used. These structs are documented here,
-and follow the GEDCOM syntax quite closely. Each of the records in
-a GEDCOM file are modelled by a separate struct, and some common sub-structures

-struct submission* gom_get_submission();
- -struct XXX* gom_get_first_XXX();
-struct XXX* gom_get_XXX_by_xref(char* xref);

The XXX stands for one of the following:-family,individual, multimedia, note, repository, source, submitter, user_rec.

-for (fam = gom_get_first_family() ; fam ; fam = fam->next) {

-
next member of the last element in the list is guaranteed to have the NULL value.previous member. But for implementation reasons the behaviour of this previous member on the edges of the linked list will not be guaranteed, i.e. it can be circular or terminated with NULL, no assumptions can be made in the application code.next and previous
-member following the above conventions. This means that the following
-piece of code traverses all children of a family (see the details of the
-different structs here):-Note that all character strings in the object model are encoded in UTF-8 (Why UTF-8?).struct family* fam = ...;
