XBio:D Taxonomic Data Model
Introduction
This page will provide information on the xBio:D taxonomic data model. Only users with taxonomic permissions and possess the taxonomic authority upon a certain group are able to manage taxonomies, so if you would like to contribute to the xBio:D taxonomic resources, please contact hol-help@osu.edu and request permission.
xBio:D Taxonomic Data Model Basics
The xBio:D taxonomic data model is modeled using a tree graph in which nodes correspond to taxonomic concepts and the edges are taxonomic relationships. Taxonomic names are treated as entities within a node that corresponds to identities for a taxon with at most one being valid. This data model can accommodate all codes of nomenclature, like the ICZN, while being amenable to the taxonomic and nomenclatural acts that are common to systematics.
An analogy that may be helpful to understand the data model is to imagine a species as a model of car. A model can have multiple spelling, different designations, and misspellings from shoddy catalogs, e.g., Corolla 2-door, Corrolla 4-door, Toyota Corolla DX, etc., but they are all the same model and thus the same concept. Each of the model spellings can be viewed as taxonomic names and the model itself is the concept. A nickname for the car model like "the goat" can be viewed like a common or vernacular name. People may use the name amongst each other, but it will never be the formal name of the model.
Let's say that the one model spelling that is preferred is "Toyota Corolla" and we consider this as the valid name for the model. There is another model, the "Toyota Sprinter", that is essentially the same car model as the "Toyota Corolla", but since it has a fundamentally different name, we treat it as a separate model. However, we deem both models to represent the same model, and since the "Toyota Corolla" name is older, we consider that to be the valid model. To map this example to the above graph, Telenomus ovivorus is equivalent to "Toyota Corolla" and Telenomus turkarkandas is equivalent to "Toyota Sprinter". "Toyota Corolla" is synonymous with "Toyota Sprinter", but since the "Corolla" name is older, it is the senior synonym while the "Sprinter" is a junior synonym. "Toyota" is the brand for the model, and can be viewed as being equivalent to Telenomus, the genus in the above graph. "Toyota", the brand, has many other car models that are made by, or members of, it with the "Toyota Corolla" being one. The brand "Toyota" is a member of the manufacturer "Toyota" in a similar way that the genus Telenomus is a member of the subfamily Telenominae and so one until eventually you reach the kingdom, Animalia.
Maintaining this analogy, let's say that the "Toyota Corolla" model is sold off to "Chevrolet". Then, a new name is added to the model concept, "Chevrolet Corolla", which becomes the valid name while the other names for the model become obsolete. "Toyota Sprinter" is still synonymous for the "Chevrolet Corolla" but is not given the name "Chevrolet Sprinter" because the name is never to be used. Since "Toyota" is no longer the brand of the "Corolla", the new parent for the model is "Chevrolet". This type of action is equivalent to a species being transferred from one genus to another.
