Field naming conventions
 * Plural form If it is not unusual for a field to have multiple values, name it using the plural form.
 * Rare cases remain singular. Example: The state field can have multiple values when it is uncertain. EG birth state in Hessen or Bavaria, would be encoded as Hessen;Bavaria, but this is rare, so the field name remains singular.
 * It is commonplace to have more than one value for "locality" (ʻAiea, Honolulu or, Bristol), so this field is "localities"
 * Numbering at endIf a field can have variants, the variant name should appear at the end. EG: date of wedding1, date of wedding2.
 * Lower case always fields and internationalized names should be all lower case, even if the name is normally capitalized. eg KMZ becomes kmz
 * Avoid hypehnation street-address unnecessarily uses a hypen.  Date-y is justifiable, since hyphenation implies that y is somehow connected to date, and helps the user figure out that it means "year"
 * Avoid abbreviation Except in the case of high use fields, avoid using short field names.
