It’s the year 2021, and it seems as though there has been little to no progress in the general quest to alleviate those costly challenges associated with integrating data across disparate data sources. Fundamentally, this problem lies at the very core of Technical Debt accumulated due to the dominance of Application Centricity over Data Centricity, with regards to solution architecture.

Enterprises and individuals alike are still asking the same age-old question:

What sits between me and my data?

Data Source Names (DSNs) are what sit between you and your data — regardless of application type or usage medium. …


This document will help you understand why Knowledge Graphs, Ontologies and Linked Data are powerful tools for digital transformation, by demonstrating how the magic of Hyperlinks extends beyond the World Wide Web.

Graphs

Understanding the essence of a graph.

Data-Driven Enterprise Transformation

Enterprises are looking to data-driven digital transformation to drive agility.

Linked Data

What is Linked Data?

Linked Data is a principled approach to structured data representation that manifests as a Web of Data.

Why is Linked Data Important?

Linked Data enables transparent access to data, courtesy of the power of hyperlinks, thereby enabling the following:

  • Integration of data across disparate data silos
  • Platform-independent data connectivity across new and existing enterprise solutions

How is Linked Data created and used?


There is no such thing as a “silver bullet” when dealing with the complexity associated with data access, integration, and management. In this post, I will be covering deeper change-sensitive bridging between COVID-19 and SARS-CoV-2 data sources and the Linked Open Data (LOD) Cloud Knowledge Graph.

Healthcare and Life Sciences Segment of the LOD Cloud Knowledge Graph

Situation Analysis

Initially, I looked to the functionality of shared Google Spreadsheets for identifying and enhancing important COVID-19 data sources published in Open Data form. This approach enabled exploitation of the fundamental power that spreadsheets bring to bear with regards to data structure analysis and manipulation e.g., …


Here is a simple tutorial that demonstrates the fact that Linked Data deployment is easier than is generally assumed.

In this variant of the tutorial I am using JSON-LD Notation rather than RDF-Turtle Notation.

Why?

I want observations that I document to be “webby”, or “web-like”, in nature; i.e., I want entity relationships that can be navigated by clicking on hyperlinks (HTTP URIs) using a follow-your-nose pattern.

Linked Data Semiotic Triangle

What?

Describe how several entities are related, leveraging the data connectivity and access prowess of Linked Data and the descriptive power of RDF sentences:

  1. a lady named “Alice”
  2. a man named “Bob”
  3. a car manufacturer…


Support for open standard protocols and document types is one of the many capabilities that distinguishes our Virtuoso platform.

In regards to Knowledge Graph exploitation, these benefits magnified via support for CalDAV which enables the use of existing Calendaring and Scheduling tools as client applications for performing Create, Read, Update, and Delete (CRUD) operations.

Here are the steps for connecting any CalDAV-compliant tool to your Virtuoso instance en route to performing CRUD operations using your preferred Calendaring & Scheduling Tool.

Prerequisites

  • Install the ODS-Framework Module which provides the Collaboration Layer known as OpenLink Data Spaces (ODS)
  • Install the ODS-Calendar Module via…


This post demonstrates how a combination of SQL (one open standard) with SPARQL (another open standard) — here comprising a Business-Intelligence–focused extension of SPARQL we call SPARQL-BI — can address a range of data manipulation operations commonly referred to as Graph Analytics.

Virtuoso’s SQL engine includes a Transitivity extension, which is surfaced in its SPARQL engine as part of the SPARQL-BI extensions to SPARQL. This functionality exists as a solution to the need to leverage SPARQL for Graph Analytics operations.

What is a Graph?

A Graph is a pictorial — a graphic aid — for representing Entity Relationship Types, i.e., …

Every Web Browser includes a bookmark manager and associated features that provide a user with the ability to save links to Web Pages they’ve visited for future recall. Unfortunately, as currently delivered, this functionality doesn’t scale and as a result is decreasingly used — net effect, a lessening ability to recall and share interesting documents (e.g., blog posts, newspaper articles, etc.).

In response to the this frailty, a number of bookmarking services emerged during the Web 2.0 era, of which del.icio.us was dominant. …
