In Jambalaya classes are represented as nodes, and slots or properties as arcs. Clicking on the node or arc filter buttons, or selecting Tools->Arc Filter, will display a panel offering filter options.

The Node Filter |
|---|---|
 Node types available depend on the type of data you are viewing. For example, in Protege one can use OWL or standard ontology backends. Typically, we have class and instance nodes, and in OWL, individuals, defined classes, logical properties, and so on. Checking or unchecking the boxes on the Node Filter window changes the visibility for this node type, hiding or showing those nodes as appropriate. Filtering a node also filters its associated arcs. Click on the node type button (to the left of the checkbox) to display node style properties. This lets you change the node background color, border type(s), and an optional background image. |

The Arc Filter |
 Arcs represent relationships between concepts, and can also be known as object properties or slots. They have types as well, and again, these will depend on your data. Jambalaya breaks arcs into 'groups', which can be used to perform actions on sets of arcs. If you click on a group of arcs, you can hide them all or show them all. In the image above, a group has been selected and the options at the top of the filter are available. You can also change settings for specific arcs by clicking on the eye icon (visibility) or the line icon (this changes arc properties, like curvature, colour, and line style). Filtering arcs does not effect the visibility of the nodes to which they are connected. |

Filters View (New!) |
 This is a new tool that let's you control the filters in Shrimp, Jambalaya, and Creole. It displays a list of the applied filters and a list of the disabled filters. Filters can be moved between the two lists and the main view will be updated. In the applied filters list, click on the "X" button to disable the filter. It will then appear in the disabled filters list below. In the disabled filters list, click on the "+" button to enable the filter. It will then appear in the applied filters list. Click on the "X" to permanently remove the filter. It will be removed from the disabled filters list. |

| Advanced Arc Filtering |
Shrimp, Jambalaya, and Creole also support the notion of 'composite' (or high level) arcs. These are pseudo-arcs representing arcs connecting nodes lower in the hierarchy. For example, in the Wines example, the arcs connecting individual wines to locations are numerous. Enabling composite arcs allows these numerous sub-arcs to be shown as one arc connecting the higher-level concepts such as Wine and Wine Region. This figure shows this feature in action:  To access this functionality, right click on a group of arcs and select "Properties...". This brings up the arc group properties. Select the colour of the arc you would like to see, as well as whether composites below a certain threshold should be filtered (e.g., don't show a composite of only 10 arcs). |
