Sorting

Automatic person directories in Omega are by default sorted by last name/first name/date. To create an existing person directory with a different sort order, you can create a copy of the directory and select the sort order for the copy.

Basic information on sorting

Sorted alphabetically

The alphabetical sorting used in Omega follows the same rules as in German telephone directories: the umlauts ä, ö, ü and the sharp S (ß) are resolved to ae , oe , ue and ss . Diacritics (e.g., accented letters) are treated like the corresponding letters of the alphabet (e.g., a for á). Special characters (e.g., underscores, hyphens, slashes), numbers, and spaces are ignored during sorting.

For sorting personal names: The primary sorting criterion is the first surname, the secondary criterion is all given names. Within the same surname/given name combination, sorting is performed by date of birth. People without a surname are sorted after ZZZZZ... People for whom neither a surname nor a given name is entered are sorted to the very end and appear there as NN .

The sorting is based on the part of the name beginning with the first capital letter. For example, the surname von_Hagen will be sorted under Hagen . Because only the part of the surname that begins with a capital letter is considered during sorting, aristocratic prefixes (generally prefixes) such as von_ and de_ are ignored. Note the effects of spelling in the following examples:

first last name sorted as
von_Nassau Nassau
From Nassau Vonnassau
de la Paz Paz
De la Paz Delapaz
Names that differ in prefix are sorted separately according to prefix: van Leyden, Peter before von der Leyden, Anne and Metz, Peter before von Metz, Peter and this in turn before Metzger, Peter .

Sorted by date

Data is sorted in ascending order, ignoring " before ", "at" , and " after " values. Missing day, month, or year values are treated as zero. Therefore, a non-existent date is always sorted to the very beginning.

Sorting methods for directories of persons

Sorted by last name/first name/date

This is the standard sorting order for directories of persons.
  1. The primary sorting criterion is the last name, after which alphabetical sorting takes place.
  2. The secondary sorting criterion is the first names, according to which an alphabetical sorting takes place within the same last name.
  3. In cases of identical surnames and first names, the results are sorted according to the first of the following dates of life: date of birth, date of baptism, date of death, date of burial.

Sorted by name/date

Recommendation: According to the specifications of most associations, this setting should be used as the sorting method for lists of persons that serve as the basis for a local family register .
  1. The primary sorting criterion is the last name, after which alphabetical sorting takes place.
  2. Within the same surname, entries are sorted in ascending order by the civil marriage date, if available; otherwise, they are sorted by the religious marriage date (secondary sorting criterion). Dates before , after , and around the civil marriage are ignored.
  3. Unmarried individuals or those without a known marriage date are sorted within the same surname according to their dates of birth and death. Individuals for whom no date is known at all are sorted to the very beginning within the same surname. Therefore, when entering information on individuals who are married but without a known marriage date, it is advisable to provide an approximate date ( around , before ) to ensure meaningful sorting even in such cases.
The spouse's life data is not taken into account during sorting.

Sorted by name/marriage/signature

This sorting differs from sorting by name/date in that if the marriage date is missing, no other date is used for sorting, and if the marriage dates are the same, the signature is also used.
  1. The primary sorting criterion is the last name, after which alphabetical sorting takes place.
  2. Within the same surname, the entries are sorted in ascending order according to the first marriage date (church marriage date, if applicable, otherwise civil marriage date) (secondary sorting criterion).
  3. If the first marriage date is not specified, or if two people have the same last name and the same first marriage date, the sorting is done alphabetically in ascending order according to the signature.

Sorted by date

This sorting method can be used to create a birth/baptism register.

The only sorting criterion is the date of birth. If the date of birth is not specified, the results are sorted by the date of baptism.

Sorted by signature

For some applications, such as analyzing lineages with multiple subjects, it can be useful to sort by signature. The signature must be chosen by the user to achieve the desired order. The sole sorting criterion is the person's signature: sorting is based on the arithmetic values of the signature characters as derived from the 8-bit ASCII character set . Digits are sorted before letters, both in their natural order. You are on the safe side if you use only the characters a..Z, 0..9 for the signatures.

Sorted by creation time/last modification

This sorting method can be used to create a data collection list.

The only sorting criterion is the date of a person's first entry or their last change, sorted in ascending order. The most recently entered or modified index cards are therefore sorted to the end.

Sorted by Kekulé numbers

The directory is sorted in ascending order by Kekulé number . Persons without a Kekulé number are sorted at the end by last name/first name/date of birth.
