== Welcome to BDI Data ==
This is a wiki instance with [http://wikiba.se/ Wikibase] support, to describe terminology data using wikibase. 

The new ABCD 3.0 Ontology was modeled in this wiki and subsequent further versions will also be developed here. 

'''This is however not the place for documentation of ABCD concepts.''' 

Please go to 
* https://abcd.tdwg.org/ontology/ for documentation of the ABCD 3.0 Ontology,
* https://abcd.tdwg.org/xml/ for documentation about the ABCD XML Schema, or 
* https://terms.tdwg.org/wiki/ABCD_2 for the documentation about individual ABCD 2 concepts

==ABCD 3.0 Modelling==
If a new concept is created, it has to be given a label and a description first. Afterwards the type of it must be assigned by using the property {{P|9}}.
The following types are available: 
* {{Q|32}} - For concepts that will be represented as classes in OWL.
* {{Q|33}} - Property to connect a class to other classes.
* {{Q|34}} - Property to connect a class to a value of a simple type.
* {{Q|14}} - A class that only allows the creation of specific instances of itself.
* {{Q|16}} - An allowed instance of a {{Q|14}} 

The type of a concept decides which properties are required, which are optional and which are not used at all.
The table below shows all used properties and their relation to the concept types.

x ... Property is required.
(x) ... Property is optional.
