cascading stylesheet (CSS)
A cascading stylesheet defines styles that control the format of HTML elements. CSS is also used to refer to the statements that appear inside a CSS stylesheet and in the style parameter on HTML elements.

An in-depth discussion of styles and stylesheets is beyond the scope of this glossary. There are many reference guides for CSS on the web, including one at w3schools that you may find useful. The official standards are published and maintained by the World Wide Web Consortium. See their CSS home page for more information.

case sensitivity
In computer parlance, case sensitivity refers to how text is processed with regards to uppercase and lowercase characters. "Case sensitive" operations consider an uppercase character to be different from a lowercase character. "Case insensitive" operations consider an uppercase character to be the same as a lowercase character.

Case sensitivity affects text comparisons. If an operation is case sensitive, then "Example" is not the same as "example".

Text comparisons are performed when sorting text, so a case sensitive sort will not sort "Example" and "example" together. Using a simple character sort, uppercase letters sort before all lowercase letters, so "Example" will sort before "apple".

Most text comparison operations in Gedcom Publisher are case insensitive: uppercase and lowercase characters are treated as being equal.

CD (compact disc) or CD-ROM (compact disc, read-only memory)
In general computer parlance, CD refers to a compact disk, a 4.75" diameter optical disc digital storage medium.
citation reference
A citation reference is a superscript number following an event, a name, a relationship, or other genealogical data that references an associated item in the following citation list.
A coaster is a DVD or CD that cannot be read. When a disc cannot be read, it is better at preventing wet cups and glasses from staining the furniture than it is at storing data!
Common Era

default sentence
The default sentence for a name or event is the sentence defined for the tag type. So, the default sentence for a particular Marriage event is the sentence defined for the Marriage tag. See custom sentence.

GEDCOM Standard
According to WikiPedia, "GEDCOM (an acronym standing for Genealogical Data Communication) is an open de facto specification for exchanging genealogical data between different genealogy software. GEDCOM was developed by The Church of Jesus Christ of Latter-day Saints [...] as an aid to genealogical research."

There are multiple versions of the GEDCOM standard. Gedcom Publisher follows version 5.5.1 as described in a document titled The GEDCOM Standard, Draft Release 5.5.1, prepared by the Family History Department of The Church of Jesus Christ of Latter-day Saints and dated 2 October 1999. While labeled a draft, version 5.5.1 is the de facto standard. The only other version in widespread use is version 5.5, released 2 January 1996. Most GEDCOM documents that claim to follow version 5.5 include structures or options defined in version 5.5.1.

All the GEDCOM standards, including version 5.5.1 and version 5.5, include ambiguous definitions and suffer from other problems. Also, because the standards do not support all the data items that are recorded by genealogy applications, GEDCOM documents include many non-standard data records. For that reason, Gedcom Publisher has been designed and implemented to support application-specific data import rules.

When used as a verb, to geocode typically means to assign a latitude and longitude to a location based on its address. In some cases, a mapping service will derive a set of coordinates, such as the outline of a city, state, or country, based on the input text.

Geocoding is an imprecise process where the results vary by the components of the address and the database and software used by the geocoding application.

image code
In Gedcom Publisher, an image code is the filename portion of an image file, i.e., the image code does not include the filetype. Gedcom Publisher populates various pull-down menus with a pre-defined set of image codes that represent image files that are defined in one or more Themes. Users can add to the set of available image codes by adding graphic files to the Input (-i) Folder. The filetype is omitted because Themes may provide image files in different formats, so Theme1 may use "background.jpg" but Theme2 may use "background.gif". The user chooses the image code "background", and Gedcom Publisher searches for background.gif, background.jpg, and background.png, in that order, and uses the first file it finds.
input folder
Gedcom Publisher creates the Input (-i) folder automatically when you make a new Gedcom Publisher file. Gedcom Publisher appends "-i" to the Gedcom Publisher file name and uses that as the Input folder name. Graphic files you supply, and any other files that should be copied to the Output (-o) folder should be placed in the Input (-i) folder.
The IPTC is a consortium of the world's major news agencies. The IPTC's primary focus is on developing and publishing industry standards for the interchange of news data. Many image editing programs support the IPTC standard for embedding metadata in the image file. See the Exhibits page for information about how Gedcom Publisher uses IPTC-format metadata stored in image files.

Open source refers to a practice where goods, products or other resources are shared. The term was first applied to software source code, but has been extended to other items such as digital graphics and digital photographs. See the WikiPedia definition for more information.
Person Entry
For each person in the database that is included in the book, Gedcom Publisher produces a person entry. The person entry includes information from the name and event tags associated with that person as well as other information about the person such as parent and child relationships.

When Gedcom Publisher is building a particular person entry, the person whose information is being processed is called the subject.

A variable expression may include a preposition (also known as a prefix) that is included in the sentence before the value of the variable but only if the variable is not empty. In the following variable expression, the preposition is "and ":

<and [PO]>

See default preposition.
regular date
A regular date includes only recognized date parts, such as a day, month, and year. A regular date may be a partial date, i.e., it may include a month and year only, or a year only. A regular date may include a modifier such as "before", "after", etc.

In contrast, an irregular date is not recognized as a date value. It might contain text that is not a recognized part of a date, or a phrase that indicates a time frame without a specific date, for example, "after the census of 1880".

Variable expressions are described in more detail on the Sentence Structures help page.
variable, variable name, or variable reference
A variable name is a symbol that is used to refer to data whose value may change. A variable reference is a variable name enclosed in brackets, e.g., [S]. Variable references are replaced by the value of the variable when Gedcom Publisher formats a sentence.
