Matrix Views

Description

Several spreadsheet-style views of an ontology, including existential fillers, individual relationships and an object properties view.

Navigate by fully functioning class/property tree
Add/remove columns to customize - show any combination of annotations/properties/features
Comma-separate values in a list for quick editing
Drag and drop object or data properties on the matrices to add columns
Drag and drop classes on the matrices to add fillers, domains and ranges
Filter annotation columns by language (to allow translation-style view)
Filter property columns by restriction type (some or only supported)
Full class expressions supported in editors

Window | Tabs menu Two default tab layouts are provided:

Property Matrix Window | Views menu All of the matrices are implemented as views so you can add them into your own custom tabs:

Class annotations
Class matrix (asserted and inferred hierarchies) - previously Class Existential MAtrix
For highly compositional ontologies a lot of time can be saved by using the Class Matrix to add multiple superclass restrictions on classes.
Add property columns to the matrix, either by drag and drop or using the toolbar add object/data property column to matrix. - Dnd will default to some restrictions, but with the add button you can specify this.
Some cells may already contain values. There can be several fillers in one cell. See below for the meaning of the highlighting.
Add values by dragging classes onto the cell or edit by clicking in a cell to start a text editor.
The column specifies the property and the restriction type.

if a cell value is

plain - filler of a restriction in a subclass (can be edited)
bold - filler of a restriction in an equivalent class (not affected by editing)
(bracketed) - this means it is an inherited from an ancestor (not affected by editing)

Multiple values in cells are separated by commas and each value is a filler for a separate sub/equivalent class restriction.

p (some) q (only) SuperA ClassE --ClassA ClassB ClassC, ClassD (ClassE ClassF Then the ontology contains:

equivalentClass(ClassA, p some ClassB) actually p some ClassB may be in an intersection

subClassOf(ClassA, p some ClassC)

subClassOf(ClassA, p some ClassD)

subClassOf(SuperA, p some ClassE) shows up as inherited for all subs of SuperA

subClassOf(ClassA, q only ClassF)

To aid multilingual label generation for entities, all matrix views allow filtering by language. To set up a view as below, follow these steps:

Enable one of the matrix tabs or add a matrix view to a current tab
Press the top left button on the menu bar Add annotation column to matrix. A dialog will appear.
Select the annotation URI in which you will create your labels
Select a language you will be adding labels for
Press OK
If you want to provide multiple translations or compare against an existing translation repeat from step 2, but select a different language
Open up your hierarchy and select the first cell you wish to edit
When entered, return drops to the next entity and you can start typing immediately
