- ANSI
- American National Standards Institute
- ASCII
- ASCII is an acronym that stands for American Standard Code for Information Interchange, a standard originally defined by ANSI which assigns the binary values used by computers to letters, numbers and symbols recognizable by humans. ASCII is described in many places on the web, such as ComputerHope.com.
- aspect ratio
- In these help pages, aspect ratio typically refers to the ratio of width to height of a picture or digital image. When resizing a digital image, it is usually best to maintain the same aspect ratio to avoid a stretched appearance.
- Before Common Era
- BCE and BC refer to the years before 1 AD / CE.
- 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 TMG to GEDCOM are case insensitive: uppercase and lowercase characters are treated as being equal.
- Common Era
- CE and AD refer to the years starting after 1 BC / BCE
- custom sentence
- A custom sentence is a sentence that has been keyed into the sentence field for a specific name or event. See default sentence.
- default preposition
- A variable expression may include a preposition (also known as a prefix) that prints before the value of the variable but only if the variable is not empty. Some variables, such as the date and place variables, have a default preposition that is displayed when the conditional variable reference does not include a user-supplied preposition.
- 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.
- deprecated
- A deprecated feature is one that is being phased out. In these Help pages, deprecated usually refers to HTML elements and parameters that have been superceded by CSS parameters.
- direct import
- TMG to GEDCOM writes GEDCOM files. Most genealogy applications will read and process GEDCOM files. Some genealogy applications will read data directly from the TMG project database, which is described as a "direct import". A direct import is usually a better choice than importing a GEDCOM file, but that depends on how well the direct import authors understood the TMG project structure, and how much of that structure they chose to support.
- 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. TMG to GEDCOM 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, TMG to GEDCOM has been designed to create custom GEDCOM records and structures.
- HRef
- HyperText Reference, which specifies the location of a web resource and is used as the destination of a hypertext link. Often called a "web address" or "URL". See the W3C's Links page.
- HTML
- HyperText Markup Language, the language used to create most web pages. The HTML standard is administered by the World Wide Web Consortium (W3C).
- HTTP
- HyperText Transfer Protocol is a set of technical rules for exchanging files on the World Wide Web. See the Wikipedia article on HTTP for more information.
- IPTC
- 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 TMG to GEDCOM uses IPTC-format metadata stored in image files.
- JPEG
- JPEG is commonly used to refer to digital image files that have been compressed with the JPEG compression method.
- JSON
- JSON, or JavaScript Object Notation, is a text-based format for exchanging data. See the Wikipedia article on JSON for more information.
- LatLong
- LatLong (or lat-long) is a common abbreviation for latitude/longitude, geographical coordinates that are used to specify precise locations. See the WikiPedia definition of geographic coordinate systems for more information.
- metadata
- Metadata is data that describes other data. In the TMG to GEDCOM help pages, metadata typically refers to textual information that describes an image that is stored inside the image file, such as a caption.
- nesting
- In computerese, nesting usually means placing one element inside another.
- open source
- 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.
- 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".
See the Dates section for more information about dates in TMG to GEDCOM.
- single-excluded
- Single-excluded data is stored in fields that begin with the single-exclusion marker "
-". Singly-excluded data can be included or excluded in TMG to GEDCOM based on the setting of the Include Single-excluded Data checkbox. - Split CD
- In TMG, a Citation Detail (CD) field that is divided into segments using the "||" characters is often called a "split CD." The segments can be included in the citation using the [CDn] notation, where N is replaced by the segment number, e.g., [CD1], [CD2].
- string
- In computer parlance, a sequence of text characters. You may edit the strings that TMG to GEDCOM uses when making a site via the Utilities > Strings... commands.
- variable expression
- A variable expression is a variable reference enclosed in "<" and ">", for example, "
<[PO]>". If the variable is empty, i.e., has no value or is excluded, the variable and the associated preposition and/or suffix are omitted from the sentence. Variable expressions are described in more detail on the Sentences 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 TMG to GEDCOM formats a sentence. - WYSIWYG
- WYSIWYG is an abbreviation for "what you see is what you get", and usually refers to editing programs that manipulate something that looks like the end result as you edit. See the WikiPedia definition for more information.
- XML
- XML is an acronym that refers to the eXtensible Markup Language, a simple, flexible text format used to interchange data between computer applications. The XML standard is administered by the World Wide Web Consortium (W3C).
