The AniNIX aims to share information. Yggdrasil holds the many worlds of information available. See [[Yggdrasil#Available Clients|Available Clients]] below for ways to access the system.
# Etymology
The most commonly accepted etymology of the name is ygg "terrible" + drasil "steed". While the name means the "terrible steed", it is usually taken to mean the "steed of the terrible one", with Yggr the epithet of the god Odin. In other words, Odin's horse, referring to the nine nights he is said to have spent hanging from the tree, or "riding the gallows", in order to acquire knowledge of the runic alphabet.
The gallows are sometimes described in Old Norse poetry as the "horse of the hanged." In the case of "terrible steed", the association with Odin may be secondary, and any number of riders possible. A third interpretation, with etymological difficulties, is "yew-column", associating the tree with the Eihwaz rune.
Fjölsvinnsmál, a poem in the Poetic Edda, refers to the World Tree as Mimameid (Old Norse: Mímameiðr, "Mímir's tree" ). The tree is also probably identical to Laerad (Old Norse: Læraðr) a tree whose leaves and branches reach down to the roof of Valhalla and provide food for the goat Heidrun (Old Norse: Heiðrún) and the stag Eikthyrnir (Old Norse: Eikþyrnir).
## The Nine Worlds
The Yggdrasil tree is home to the Nine Worlds in Norse Cosmology. The worlds are:
In the north: Niflheim
In the east: Jotunheim
In the south: Musspelheim
In the west: Vanaheim
In the center: Midgard
Above: Alfheim and Asgard
Below: Svartalfheim and Helheim
## Residents
The World Tree is inhabited by several animals, the Nίðhӧggr, pet dragon of the goddess Hel which chews the roots of the tree which bind it, Veðrfӧlnir the rooster, who will crow when Ragnarok occurs, Ratatӧsk the squirrel, who carries messages of hate between the eagle and the Nίðhӧggr. This eagle, who is not named, is said to have knowledge of many things, and on its head sits Veðrfӧlnir. The significance of Veðrfӧlnir is unclear but John Lindow suggests that it may represent a higher faculty of wisdom, possibly sent out to acquire knowledge in a similar manner as Odin's ravens Hugin and Munin.
The original Norn was undoubtedly Urd, a word which can be translated to mean "Fate". The Well of Urd, which was situated at the base of the great cosmic tree Yggdrasil, is named after this Norn. The two additional Norns that are known by name are Verdandi ("Present" [or "Necessity" in some versions]) and Skuld ("Future" [or "Being" in some versions]). All three Norns live at the Well of Urd in Asgard. According to Norse mythology, nothing lasts forever, and even the great Yggdrasil has been said to decay one day. The Norns try to stop or slow this process by pouring mud and water from the Well of Urd over its branches. The magical liquid stops the decaying process for a short time.
## Relevance to the Service
Yggdrasil is a knowledge repository for the AniNIX -- it literally "holds the worlds" for the network's data content.
# Relevant Files and Software
All configuration is cached inside the service -- we log to [file:///var/lib/emby/logs Emby's logs directory] and data lives in [file:///var/lib/emby /var/lib/emby]. You can build it using the [https://aninix.net/foundation/ConfigPackages ConfigPackages], which will handle the initial directory installation along with an emby-server service.
To keep a consistent color scheme, we add the following under the Emby Server Dashboard > Advanced > Branding. This does not help mobile, but it does make a significant help to computer use.

LDAP in Emby world is controlled by a dotnet plugin. Bind DN, search filters, and initial user setup are controlled within the plugin from the server admin panel; the plugin can be pulled from the plugin catalog inside Emby. Usage of it is dependent on an Emby premiere membership -- failure to have such will result in "System.Exception: Emby Premiere required for LDAP" messages in the logs. However, this can sometimes be a false positive if preceded by lines of "Error Plugin: Error checking registration status of ldapfeature" -- the latter will be caused by a [https://emby.media/community/index.php?/topic/59531-external-ssl-connections-crashing/page-3#entry589538 documented issue with dotnet core] that can be resolved by "sudo chmod a+r /etc/ssl/certs/*".
