The Parent Plugin
The Parent Plugin displays the immediate parents of the
current sub-selection term:

Each line in the display represents a parent link from the currently selected
term to another term. From left to right, the fields in each line are:
- Relationship type dropdown - This is a list of all the relationship types in the
ontology. The current relationship type for this link is selected. To change
the relationship type of this link, choose a new item from the dropdown list.
- Parent term - This is the id and name of the parent term of this link. Click the id
to select the parent term.
- Intersection checkbox - Whether or not this is an
intersection link. Click this checkbox to designate this link as an
intersection link. This method of specifying intersection links is
not
recommended. Use the text
editor instead.
- Necessity checkbox - Whether this link is marked
"necessary". Links that aren't marked necessary are ignored by the reasoner.
Click this checkbox to designate this link as necessary.
- Inverse checkbox - Whether this link is marked "inverse
necessary". This means that the inverse of this link is necessarily true.
Click this checkbox to designate this link as inverse necessary.
- Cardinality control - Sets the cardinality of this link.
This information is not currently used.
- Namespace control - This is a list of all the namespaces
in the ontology. This current namespace for this link is selected. To change
the namespace of this link, select a new namespace from the dropdown.
- Delete button - Press this button to delete this parent
link.
To add a new parent link, drag the parent term onto the "Drop terms here to
add new parents" button. A new link will be added with the dropped term as the
parent, and is_a as the relationship type.
