Step 3

  • show that reasoner could do something with parent-child relationships
  • make encoding of dates separate from the way they are recorded in the document itself. Can note that those who know XML may recognize this manner of specifying numbers alongside a literal according to a certain protocol.

Step 4

  • add sequence in list
  • Break out x annotation

Step 6

  • Reconcile: link diseases to Dbpedia
  • I don't think my profession/occupation idea is well formed.
  • describe translation into other formats (XML?), which is a bit advantage. And can be moved from one triplestore to another. good Sustainability.
  • show how to turn it back into csv, if necessary.

Older version leftovers

A simple option is Fuseki. Download it from this page (scroll down to the Apache Jena Fuseki heading, and download the apache-jena-fuseki.2.4.0.zip file. Unzip this file. Then, using the command line (in Terminal in Linux or Mac, or in Command Prompt in Windows), use cd (Linux/Mac) or dir (Windows) to navigate to the Fuseki folder you created. Then use the command ./fuseki-server (Linux/Mac) or ./fuseki-server.bat (Windows) to start the server. Open a web browser and type localhost:3030 into the address bar, and you are set to go.

We'll now need to upload our data file into Fuseki. Add a new dataset (using in-memory for this temporary experiment), give it a name that makes sense, then click upload data and attach our Turtle file. (When you construct a dataset yourself, you might encounter upload errors if you have made certain syntax errors in typing. Most often, it's a misplaced semicolon or period that is responsible. If you have an error, paste the Turtle code into this tool, which will locate it for you.)

Now we're set to interact with the data using the SPARQL query language, which as we've seen is the subject of another Programming Historian tutorial. Switch to the Fuseki query interface and run SELECT * WHERE {?s ?p ?o}, the standard SPARQL query that lists all of the information entered.
