Visualizing Pod data

These simple instructions walk you through the 10-minute process of registering for the Free edition of the commercial triplestore from Ontotext (named GraphDB), installing that triplestore, creating a new repository, loading some dummy Pod data into that repository, and finally visualizing that Pod data yourself.

Install Free triplestore on your own machine:

  • Go to https://www.ontotext.com/products/graphdb/graphdb-free/ and register (there’s no longer any need to use a real email address - see the next step!).

  • You can wait for the confirmation email and follow the instructions to ”Run GraphDB as a desktop installation", or just register using any email address and then simply click on the relevant operating system under the “GraphDB Download Links“ section to install GraphDB immediately!.

Run GraphDB

  • Execute GraphDB.

Create a new repository

We'll now simply follow the introductory "Welcome to GraphDB" steps, which we'll also walk through below:

To create a new empty repository:

  • From the main menu (on the left-hand-side), select "Setup | Repositories".
  • Click the "Create new repository" button.
  • Select the first "GraphDB Repository" option.
  • Provide any name (without spaces!) for the "Repository ID" field, e.g., "Inrupt-SamplePod".
  • Click the "Create" button at the bottom of the page.

Load example Pod data:

  • From the main menu (on the left-hand-side), select "Import".
  • Connect to the repository you’ve just created.
  • Select the middle option, "Get RDF data from a URL".
  • Enter the URL of our example Pod data file: https://storage.inrupt.com/6441a53f-01c5-478b-b701-52a8797ba988/public/PodPat.trig (or import the local file: ../../resources/test/PodPat.trig)
  • Click on the "Import".

Visualize and interact with the Pod data yourself!

  • From the main menu (on the left-hand-side), select "Explore | Visual graph".
  • In the top "Easy graph" section, simply copy-and-paste this URL: https://pat.best-pod-provider.com/profile/card#me
  • ...and click the "Show" button
  • Now try double-clicking on the nodes to expand them and explore (see a sample expanded view here).

UI Navigation Tips

  • Dragging-and-dropping any node ‘pins’ it to its dropped position.
  • Single click on any node to see its ‘Properties’ in the right-hand sidebar. Single clicking that node again will dismiss the sidebar.
  • Hovering over a node pops up a nice icon menu (from which you can remove the node (just from the visualization, not the database!), etc.), but these icons only appear if the sidebar is dismissed (so single click the node to dismiss the sidebar first, if needed).
  • To ‘restart’ the visualization (e.g., if things get cluttered or confusing), simply use -R to refresh and start navigating again.
  • Note that the sidebar only displays properties whose values are literals, not links (IRIs).
