===Release information===
===Release information===
Information related to the actual ''release'' of the file: ''group'', ''release date'', ''CRC status'' and ''version''. If the origin of a file is unknown, i.e. ''no group'', then none of these fields have any meaning and should therefore not be set.
Information related to the actual ''release'' of the file: ''group'', ''release date'', ''CRC status'' and ''version''. If the origin of a file is unknown, i.e. ''no group'', then most of these fields have no meaning and should therefore not be set. Release date can be set for no group files, but only when it can be reliably determined.


====Group====
====Group====
Line 34: Line 34:


====Release date====
====Release date====
The date when the group released the file. Usually provided on the group's homepage or on some other release info site like [http://www.envirosphere.com/ Envirosphere] or [http://baka-updates.com/ Baka Updates].
The date when the group released the file. Usually provided on the group's homepage or on the relevant torrent tracker page. Release dates should be added according to the time of release in the UTC time zone, so sources whose timezone is known are preferred over ones displaying dates in unknown timezones.


====CRC status====
====CRC/hash status====
Indicates whether the file entry in AniDB represents a perfect copy of the original file or not. You may request a change of this status if it hasn't been checked yet. Read more about [[Wikipedia:File verification|file verification]] if you are unfamiliar with this subject.

{{eyecatch|Note|Not all groups provide checksums for their files. This means that this status has no meaning and will have the value "not checked against official CRC/Hash".}}

{{eyecatch|Note|Not all groups provide CRC checksums for their files. This means that this status has no meaning and will have the value "not checked against official CRC".}}
=====Allowed sources for official hash=====
* Official .sfv (CRC checksum) or .md5 (MD5 checksum) files (good source)
* CRC listing on official page or in the topic of the group's IRC channel (good source)
* CRC tag in the filename:
** If the file is from the fansub group's official torrent or DDL, then the file name is acceptable. (good source)
** CRC tags added afterwards by third parties should not be considered a valid source.
** It should be noted that you should also check the actual calculated CRC of your file and compare it to the CRC in the filename to ensure that you don't yourself have a corrupted file.

=====No-lookthrough rule for CRC/hash verification=====
CRCs and other hashsums are only considered valid for verification if they are calculated '''directly''' from the target file in its entirety. This means that indirect checksums like the following ones are not to be considered:
* Checksums of a ZIP/RAR/etc. archive (or set of archives) containing the file in question, even if the archive only contains one file
* The inherent block-level checksums used by the BitTorrent protocol


====Version====
====Version====
Sometimes the group makes mistakes and wants to correct them by releasing a second (third, fourth...) version, usually called ''v2'' (''v3, v4, ...''). This field is usually based on information in the file name (where no information normally means ''version 1'').
Sometimes the group makes mistakes and wants to correct them by releasing a second (third, fourth...) version, usually called ''v2'' (''v3, v4, ...''). This field is usually based on information in the file name (where no information normally means ''version 1'').


Even if a group releases two files of the same episode it does not mean that the first has to be marked ''v1'' and the second ''v2''. There are other reasons to do something like that other than correcting mistakes like; different source (DTV/DVD), different sub languages, high and low quality versions, etc.
'''IMPORTANT''': Even if a group releases two files of the same episode it does not mean that the first has to be marked ''v1'' and the second has to be marked ''v2''. There are other reasons to do something like that other than correcting mistakes, such as: different source (DTV/DVD), different sub languages, dual audio vs single audio releases, high and low quality versions, etc.
 
'''Discretion should be applied''' when "other reasons" are the cause of multiple releases. For example, if the group's intent is to release as a final product only a dual audio release, but they release a single audio release as a "v0" or "draft" version, then we should consider this single audio "draft" within the version continuity of any subsequent dual audio releases.  However, if the group's intent is to release as a final product both a single and dual audio release, do not combine the versioning continuity.
 
{{eyecatch|Note|We generally do not consider resolution changes and source changes as version bumps. That being said, you are free to add a file comment, indicating a file is marked as v2 and intended to replace a certain file. For example: <pre>Labelled as v2 of https://anidb.net/f2030447</pre>}}

====Censored====
====Censored====
Mainly used for files with pornographic content.
Only used and available for files with pornographic content. In rare borderline anime entries not classified as 18 Restricted, both uncensored and censored versions may still be available; in this case, include "Censored" or "Uncensored" in the file description field instead.


====Source====
====Source====
The ''original source of the content''. Possible values are; ''unknown, camcorder, TV, DTV, HDTV, VHS, VCD, SVCD, LD, DVD, HKDVD, HD-DVD, Blu-ray, www.''
The '''''original''' source of the content''. Possible values are; ''unknown, camcorder, TV (ie, analog TV), DTV, HDTV, VHS, VCD, SVCD, LD, DVD, HKDVD, HD-DVD, Blu-ray, www.''
 
=====Look-through considerations for Source field=====
When considering source, we look at from which release '''by the original publisher/producer''' this file originated.  For example, if a fansub released a file that was a rip from a web streaming website, but the web streaming website itself ripped its video from a BDMV, then the fansub-released file has its source marked as BD; the original publisher/producer source is the BD release, and not an HDTV release (i.e. video capture of a Japanese TV channel), and not a web simulcast (i.e. video rip from a streaming site like Crunchyroll, Funimation, or Daisuki).
 
====Source field for standalone subtitle files====
#When standalone subtitle files are released together with video files and the subtitles come from '''the same source as the video''', mark the subtitles as the same source as the video files.
#When standalone subtitle files are released together with video files and the subtitles come from '''a different source than the video''', mark the subtitles as the source where the subtitles came from, and apply look-through rules.
##For example, [Dmon] releases BD source files, and attached to this release are standalone subtitle files ripped from [HorribleSubs] (and possibly edited by the fansub). Since the standalone subtitles are not from the BD, their actual source is documented.  Applying the look-through rules; [HorribleSubs] rips from Crunchyroll, so the standalone subtitle files are set as www.
##If the source of the subtitle is an original fan translation, mark the subtitle file source the same source as the original fan translation's release.
#For standalone subtitle files released on their own without video files:
##If the subtitles are 100% fan translations, mark the source as unknown.
##If the subtitles were ripped from a web streaming service such as Crunchyroll, either a direct rip or an indirect rip by extracting from another fansub's release (i.e. taking the subtitle track from [HorribleSubs]' rip of Crunchyroll), mark the source as www.
##If the subtitles were ripped from a home media release (LD, VHS, VCD, DVD, BD, etc), either directly from the home media or indirectly by extracting from another fansub's release (i.e. taking the subtitle track from [Exiled-Destiny]'s rip of a BD), mark the source as the corresponding media type.
 
====Quality field for standalone subtitle files====
The quality field is intended to indicate encode quality for video and audio; as such it is much less meaningful for standalone subtitle files.  In consideration of this fact, the following general guidelines apply for the quality field as it relates to standalone subtitle files.
<br>
#When standalone subtitle files are released together with video files and the subtitles come from '''the same source as the video''', mark the subtitles at the same quality level as the video files. If there are multiple concurrent video releases (i.e. 720p and 1080p) where each release has a different quality level, but the subtitles are meant to be used for both sets of videos, set the quality level of the subtitles to match the higher quality release's level.
#When standalone subtitle files are released together with video files and the subtitles come from '''a different source than the video''', mark the subtitles at the same quality level as the originating source.
#For standalone subtitle files released on their own without video files:
##If the subtitles are 100% fan translations, mark the quality as unknown.
##If the subtitles were ripped from a web streaming service such as Crunchyroll, either a direct rip or an indirect rip by extracting from another fansub's release (i.e. taking the subtitle track from [HorribleSubs]' rip of Crunchyroll), mark the quality as unknown.
##If the subtitles were ripped from a home media release (LD, VHS, VCD, DVD, BD, etc), either directly from the home media or indirectly by extracting from another fansub's release (i.e. taking the subtitle track from [Exiled-Destiny]'s rip of a BD), mark the quality as unknown.


====Quality====
====Quality for non-subtitle files====
This is a very arbitrary field. It depends completely on the eye of the beholder. You should not put too much meaning into it, but rather use it as a general pointer of quality. Possible values are; ''eyecancer, very low, low, med, high, very high.''

As a '''general''' guideline, refer to the below for a soft-rule convention that is generally followed.  The below table can be seen as a "default" or "starting point".  If a particular file has sub-par quality, mark down its qualid field relative to the default, as appropriate.  Also note, the historical context of the anime should be kept in mind.  For example. if an anime is released in the 70s, and the highest quality medium of release is LD, it may be appropriate to use the higher range of tehbump the quality field  up a level for the LD release, relative to the defaults below; the goal is to use the qualid field as a differentiator, to identify the LD release as the definitive release relative to other options that may be available (TV, VHS, etc).

'''Note:''' All items highlighted in red below are upscales by definition, as the specifications of the mentioned media do not reach into those resolution ranges.  Items in bold signify the more common qualid (if applicable), where more than 1 is specified.

{{missing}}
This section provides some basic insight on how many users claim to have had this file and what kind of media they currently have it on. The following statistics are given:
* ''internal'': The number of users who currently have the file on their hard disk.
* ''external'': The number of users who have stored this file on an external storage, such as a NAS or a burned DVD.
* ''deleted'': The number of users who formerly had this file but don't have it anymore.
* ''unknown'': The number of users who haven't specified the location of this file on their mylist.
* ''total'': The total number of users with this file on their mylist. Clicking on this link opens a detailed list of those users.
 
Do note that not all users share the storage status of their files publicly, or in some cases don't even allow to see you on the user list, and in this case the first four numbers may not sum up to the total number of users.

The general rule is that [[Animeentries:Fileentries|file entries]] in AniDB are supposed to be useful for a larger group of users. Adding private files is therefore '''not allowed'''.

'''What is a private / personal file?'''
A private or personal file is a file that you create for yourself.  It is a file that is not released ''publicly on the internet''.  For example, if you reencode a file for your own use, or you remux a bunch of files together to create a new file, these are private files as they are only available for your personal consumption.
As a general statement, if the files were not publicly on the internet, they should not be added to AniDB.  "Published on the internet" includes:
* public trackers like Nyaa
* private trackers like BakaBT
* DDL links published on the fansub group's blog
* XDCC bots on IRC
Personal files are '''NOT''' to be added to AniDB.
