Basic information

These are the basic categories of information contained on almost all entries.
This ought to be pretty obvious. It's the title of a work. For television series, there is also Series Title, which is the title of the overarching series, and Episode Title, which is the title of an individual episode.
Alternate Title
Movies especially will often have secondary titles. A title used while it was a "work-in-progress", titles used for localization, or even titles that change depending upon versions (Director's Cut, Ultimate Edition, etc.) are all examples. These are used to make this wiki more searchable. Sometimes you know a movie by one title, while it's filed under a different title; hypothetically, you'll still be able to find that movie, assuming that it has an entry here.
Whether a TV series, a series of movies (a la Star Wars), or a series of related books, this is a way to tie them together. There will a be link that will use a tag to show all entries related to that series. Ex: Family Guy.
Year of copyright, or publication if not applicable. This will also distinguish between two works that share the same title but are not simply republications of the same content.
International Standard Book Number (wikipedia) is the standard identification number for a book, specific to publisher and edition. It is the most accurate way to find a specific book, and will also help identify if a specified passage is included in the entry, but is not in the copy that you're reading.
Produced in
The country of production or the home country of a production company. An American author will have "United States" as an entry, even if he wrote his novel while living in Peru.
Film length
For movies and television shows this is the duration, in minutes, of the entire episode or film.
Episode length
The base language of dialogue for a particular work from which an entry is being produced. If you're watching a Japanese movie with subtitles or even dubbing, this entry should still list "Japanese", though you may wish to add a note that your entry is based off of the subtitles as sometimes localization can change the meaning of dialogue or narration.
Film type
Identifies a style and/or audience for a work. Films might be, for example, mainstream or adult, animated, silent, etc. A song might be rap, ballad, folk song, etc. This is a fairly generic bit of information, but helpful.
Literature type
Mythology type
Song genre
Show type
Incest summary
This is a summary of the types of incest within a work. Mother-son, Grandfather-grandson, Greataunt-Greatniece, etc. There may be one or more of each type listed, but there will be at least one reference to each type within the work.
Relevant Characters
Perhaps a bit of an oversimplification, but this is a list of the characters who are seen as having incestuous relationships with others. Characters who are not (or at least aren't presumed to be) incestuous should not be listed here, though they may well play a part in the incestuous relationships in the work.
Specific Scenes
Using page numbers, or time in hh:mm:ss format, this identifies where in a work the incestuous relationship is referenced, implied, or depicted.
For mythology and other works which might not provide easy page references or time frames, the incestuous relationship will simply be written up as summary paragraphs.
Related Pages
If this work relates to another work (such as a book that based on a novel), a reference will be provided to link to an entry for that work as well.
External Links
As redundant as it is to state, links to external sites relating to an entry. For films, Internet Movie Database is common, or for adult films Internet Adult Film Database. If none of these sites is available, any other sites that might contain more information on a work will be here, though a reference page is much preferred over a sales pages.

Detail information

Within each of these classifications, these are some typical entries. This is not a complete glossary, but an ongoing effort. Let a Wiki member know if you know of anything that would be helpful to add.
Film type
Usually black and white, with no sound. These are very old films from the silent era.
A made-for-TV movie. This should be combined with other descriptive terms; Mainstream, Documentary, etc.
A non-fiction work that describes, depicts, or alludes to an incestuous relationship.
A work that is generally focused toward a non-erotic story. By MPAA Film Rating System standards (wikipedia), these will generally have a rating of PG-13 or less, though there are some exceptions (e.g. when violence is the cause of an R rating). This will include biographies that aren't scholarly works.
A work that is wholly or mostly animated. Ex: Family Guy
A work that is generally focused toward an erotic story, but its depictions veer away from explicit depictions. These will generally carry an R rating, and contain nudity but not show penetration or sexual body fluids.
A work that is sexually explicit and shown in full detail, as the producer's legal restrictions may allow. The digital mosaic overlaying genitals in many Japanese movies, for example, would not preclude their inclusion as Adult film types, provided that they still depict explicit sex acts otherwise.
Literature Type
A book, eBook, pamphlet, etc. This is a discrete document similar to the age-old book format.
Japanese-style picture art. It could be considered a comic book, but the distinctive art style sets it apart. Generally, this tag is accompanied by the [b]book[/b] tag. For simplicity, manhwa (the Korean equivalent of manga) and other formats of similar style will be included under this tag.
Web Page
Web content that is not a simple, paginated document. A site dedicated to documenting a family history might well fit this type.
Web Comic
Distinct from a Web Page or Book, this is sequential art in which the visual representation comprises a large part of the story depicted.
peeping non-nude
Watching some relation for erotic purposes. While following one's mother to determine if she is a murderess would not fit the criteria, following her when she meets her lover would.
peeping nude
As peeping non-nude, but for the exposure of sex organs.
A reference to either an incestuous act or incestuous desire. Characters talking about their incestuous relationships, or desire for a family member, falls into this category.
A joke about incest. This is entirely in dialogue, and contains no element of truth to either the joker(s) or the object(s) of the joke. An unintentionally factual jest would fall under the referenced category.
A reference to incest that is not explicitly shown, but is reasonable to expect that it occurred. Ex: a brother and sister enter a closet together and come out, both disheveled and the brother with several lipstick stains on his face and shirt.
foreplay non-nude
Kissing, non-penetrative fondling, lusty glances, etc. If this could be accomplished in most public places without risk of arrest (in the United States), it would probably fall under foreplay non-nude. Frottage (wikipedia) would still be considered foreplay, though might well be considered softcore without clothing.
foreplay nude
As foreplay non-nude, but for the exposure of sex organs.
softcore non-nude
Any act beyond foreplay that is not shown in explicit detail, and does not involve the exposure of sex organs. A couple apparently having sex, but completely covered by a substantial sheet or a blanket would fit softcore non-nude.
softcore nude
As softcore non-nude, but for the exposure of sex organs.
Explicit sexual acts including oral sex, intercourse, or typically any direct genital manipulation between two people.

Commonly used tags

These are tags added to a page after it has been created to allow easier filtering and searching.
Note: When defining relationships, the word-order of the relationship is:
  1. Elder First (ex: Mother-daughter incest) This is based on stereotypical definitions of the familiar relationship rather than the exact case. Thus even if a 30-year old man has a 25-year old aunt, the citation will still use Aunt-nephew incest rather than the opposite order, to maintain consistency.
  2. Male First (ex: Brother-sister incest) As with the previous rule, this will be based on broad definitions. While a sister may be older than her brother, Brother-sister incest is still used because siblings are considered to be in the same generic age bracket compared with a parent-child relationship.
Actor Name
Actors and actresses should be included as tags on an entry's page so that it can be easily cross-referenced with other entries including that person.
A television or movie series will have the tag included for easy cross-referenced.
incest on film
These keywords identify the type of entry. This is helpful for those looking for all mythology, all songs, etc. without performing a search of questionable reliability.
incest on television
incest in literature
incest in song
incest in mythology
incest in history
Film Type words
Mainstream, adult, animated, etc. This allows for easy cross-referencing for those interested in animated entries, adult films, etc.
missing information
There is information missing from this entry. It's not uncommon for an actor to be uncredited, or not even to appear on-screen, thus this tag should be provided. This helps those who seek to improve the wiki by being able to identify entries that are "Work in Progress".
The incest cited is "direct" in nature, but one or both of the participants is adopted. The relationship will be tagged as-is, but the adoption tag is used to provide more explanation. This tag is not necessary for a "step" relationship, such as a father adopting a son, then marrying a woman who sleeps with the son, which would be a mother-stepson relationship.
mother-son incest (example)
Incest involving a mother and her son.
There is one or more incestuous relationship involved in this work that is by marriage (mother-stepson, brother-stepsister, etc.) This should also be accompanied by either step-siblings and/or step-parent, as well as the specific relationship, for easier filtering.
mother-stepson incest
Incest involving a stepmother and her stepson. The "step" prefix is omitted for brevity, as it is with all marriage-induced incestuous relationships. For anything outside of the immediate family, omit the "step" prefix altogether. grandmother-stepgrandson is simply too cumbersome.
mother-stepdaughter incest
father-stepson incest
father-stepdaughter incest
Indicates that a relationship-by-marriage exists between siblings.
Indicates that a relationship-by-marriage exists between a parent and child.
