SNIK Graph Manual

Multiview Functionality

SNIK Graph supports the organization and management of different partial models in separate views.To copy a part of the whole graph, press 'C' or 'S' and to insert it into a new model press 'V' or 'P'.

Search Field

Search the currently active view for resources by entering a full or partial name.

View Specific Menu

The view-specific menu can be found in the upper right position of each view, described from left to right.

Tightlayoutsign

Compoundlayoutsign

Compound layout

Addsign

Open new Tab

Plussign

Zoom in

Minussign

Menu

File

Holds different file options like loading and saving the graph in different ways.

Load From SPARQL Endpoint

Discard the currently loaded graph and load all ontologies of SNIK.

Load Session

Load a complete session from a Cytoscape JSON File. Caution: Discards all changes!

Load Partial Graph

Load a saved view (partial graph) and include it in the current session.

Load Layout Of Partial Graph

Load a saved layout of a partial graph and include it in the current session.

Save Session

Save the complete Session (all views).

Save Complete SNIK Graph As Cytoscape File

Save the complete SNIK graph to a Cytoscape file.

Save Current Partial Graph

Save only the currently active view (partial graph).

Save Layout Of Current Partial Graph

Save only the position information of the nodes currently not hidden.

Recalculate Layout And Replace In Browser Cache

Recalculate the position of all visible nodes. May take a while when a large number of nodes are visible.

Save PNG Image Of Visible Region

Save a screenshot of the currently active view.

Save PNG Image Of Complete Partial Graph

Save an image of the whole graph with the same pixel density as the current view.

Save PNG Image Of Visible Region (high Res)

Save an image of the current view with a high resolution, for example for printing.

Save PNG Image Of Complete Partial Graph (high Res)

Save an image of the whole graph with a high resolution, for example for printing.

Filter

A collection of filters to display relevant subgraphs. Filters are applied to all open views.

Meta

The Meta Ontology provides common superclasses and properties for the subontologies of SNIK.

BB

Based on the book "Health Information Systems Ontology–Architectures and Strategies".

OB

Based on the book"IT-Projektmanagement im Gesundheitswesen - Lehrbuch und Projektleitfaden.

HE

Based on the book "Informationsmanagement: Grundlagen, Aufgaben, Methoden".

CioX

Based on interviews about the Health Information System with Department B1, the Department for Information Management, of the Uniklinikum Leipzig.

Role

Who...

Function

...does what...

EntityType

...and which information is therefore needed.

Options

Here you can find different checkboxes that toggle the behaviour of SNIK Graph. These are applied to all open views.

Separate Subs

Spread the SNIK Graph into subgraphs of the subontologies.

Cumulative Search

Keep previous search results visible when searching again.

Show Grid

shows a grid that supports better organizing of nodes.

Combine Match

Highlights groups of classes representing the same concept from different subontologies (matches) by placing them in boxes. Use "move matches on top of each other" or "move matches nearby" to shrink those boxes.

ShowInstances

Display instances of SNIK Classes, if loaded via parameter.

Day Mode

White background. Saves ink when printing.

Dev Mode

Additional context menu entries for developers.

Ext Mode

Additional context menu entries for power users.

Layout

This part of the menu holds the layout features.

Show Close Matches

Shows (unhides) all nodes that are connected via close matches to visible nodes.

Recalculate Layout

Hotkey: Ctrl+Alt+L. Recalculates the position of all selected nodes, or all visible nodes if there are not at least two selected nodes. Can take a while if there are many visible nodes.

Tight Layout

Hotkey: Ctrl+Alt+T. You can use this for a more narrow view.

Compound Layout

Hotkey: Ctrl+Alt+C. Layout that tries to places combined matches next to each other.

Move Matches On Top Of Each Other

Requires enabled "Combine Matching" option. Places all matching nodes in the center of their group.

Move Matches Nearby

Requires enabled "Combine Matching" option. Places all matching nodes in a small circle in their group.

BB Chapter Search

Presents you all chapters of the "blue book" and lets you build a subgraph out of selected chapters .

OB Chapter Search

Presents you all chapters of the "orange book" and lets you build a subgraph out of selected chapters .

Subontology Connectivity

Shows the connectivity between chosen Subontologies, i.e. between BB and OB, in a new tab.

Reset Main Graph

Resets all the layout operations to get you back to the starting point of the visualization.

Change Title Of Active Partial Graph

Opens a prompt to change the title of the currently active view.

Services

Other ways to access SNIK.

SPARQL Endpoint

Expert interface for the SPARQL Protocol and RDF Query Language endpoint.

RDF Browser

Browse complete descriptions of resources in the RDF browser.

Language

Language switch, you can choose between English, German and Persian. Ontologies may not or not fully support all available languages.

Help

Common Help Menu, holds e.g. this manual

Context Menu

Right click on a node/edge to open the context menu and choose among:

Basic Menu Items

Description (if Existing)

Opens the node in an RDF browser, which shows all its properties and values.

Star

Highlights and expands the node and all its directly connected nodes.

Incoming Star

Highlights and expands the node and all neighbours directly connected via incoming edges.

Outgoing Star

Highlights and expands the node and all neighbours directly connected via outgoing edges.

Path

Shortest Path between a selected source and this node.

Spiderworm

The Spider Worm consists of the shortest path between a selected source and this node plus all direct neighbours. Displaying a spiderworm hides all other nodes and edges.

Edit Or Report

If you are a domain expert and notice incorrectly modelled facts or connections of a node, feel free to send us an issue.

Combine Close Matches

Merge equivalent classes from different subontologies.

Class Use

Visualize the interplay of role, function and entity type (related to the Meta model).

Hide

Hide the selected item until the view is resetted.

Set Path As Source

Set the starting point for path operations.

Confirm Link

Confirm that the automatically generated interlink is correct.

Dev Mode

Remove Permanently

Send us an issue to delete the selected item permanently. Also removes it until graph is reloaded.

Debug

Get debug information to the edge/node from the JSON File

Ext Mode

Doublestar

The double star is like the spiderworm but shows connected nodes for both source and target, not just the target.

Starpath

Creates a path and star (expand) every node along it.

Circle Star

A star (expansion of the node) using a circular layout. Hides all other nodes.

LodLive

Third party data visualization exploration tool.
