{% trans "What are metadata types?" %}

{% blocktrans %}A metadata type defines the characteristics of a value of some kind that can be attached to a document. Examples of metadata types are: a client name, a date, or a project to which several documents belong. A metadata type's name is the internal identifier with which it can be referenced to by other modules such as the indexing module, the title is the value that is shown to the users, the default value is the value an instance of this metadata type will have initially, and the lookup value turns an instance of a metadata of this type into a choice list which options are the result of the lookup's code execution.{% endblocktrans %}
