You don't need to be a Programmer to create and publish web content deployed using Linked Data principles

snevitt · July 7, 2020, 6:25pm

Recently I was tasked with producing auto generated HTML-based Structured Data Web Pages - my first reaction
" I don’t have the skill set , I have no experience programming!"

How wrong was I

You really don’t need to be a Programmer to exploit the power of RDF statements deployed using Linked Data principles, here are links to a collection of live Knowledge Graph and Virtuoso Sponger descriptions for which I contributed content in the form of RDF-Turtle statements:

How?

The steps were as follows:

Described Blog Posts associated with topics such as Knowledge Graph and Virtuoso’s Sponger Middleware module using a collection of RDF-Turtle statements I crafted by hand using the editor provided by Discourse (the platform that underlies this discussion forum)
Reviewed by statements using the OSDS browser extension – using its ability to visualize and error check RDF-Turtle embedded in text editing spaces using Nanotation
Requested upload of my RDF-Turtle statements to a Named Graph (Virtuoso DBMS hosted Document repository)

Once the steps above are completed, which already demonstrates the power of RDF-Turtle deployed using Linked Data, inline, courtesy of Nanotation. I simply leave the OSDI Engine instance that drives our Web Site to inject my additional content into an existing Web Page Template.

Here are my notes that describe Blog Posts associated with “Knowledge Graph” as the main topic:

## Turtle End ##

Note : If you have OpenLink Structured Data Sniffer (OSDS) Browser extension installed it will reveal the structured meta data embedded within my document. See image below

Screencast Demo

Here is a video demonstration of me using OSDS to review and verify the RDF-Turtle that I have embedded in this forum post

As I said I am not a programmer and have no programming experience, I simply followed the principles outlined in the following OpenLink Software community forum posts:

You don't need to be a Programmer to create and publish web content deployed using Linked Data principles

How?
