The Inelegance of having Brothers and Sisters

by Michael Uschold | Feb 10, 2017 | Knowledge Graphs & Ontologies

This blog follows from a recent blog by Dan Carey called Screwdrivers and Properties. It points to a longer whitepaper on the topic of avoiding property proliferation. One way we keep the number of primitives small is to avoid creating a subproperty if its meaning is...

Whitepaper: Avoiding Property Proliferation

by Dan Carey | Feb 7, 2017 | Knowledge Graphs & Ontologies

Domain and range for ontological properties are not about data integrity, but logical necessity. Misusing them leads to an inelegant (and unnecessary) proliferation of properties. Logical Necessity Meets Elegance Screwdrivers generally have only a small set of head...

Screwdrivers & Properties

by Dan Carey | Jan 27, 2017 | Knowledge Graphs & Ontologies

Screwdrivers generally have only a small set of head configurations (flat, Phillips, hex) because the intention is to make accessing contents or securing parts easy (or at least uniform). Now imagine how frustrating it would be if every screw and bolt in your house or...

Binary Instances

by Michael Uschold | Jan 26, 2017 | Knowledge Graphs & Ontologies

Sometimes when we’re designing ontologies we’re faced with design choices that would lead us to create what we call “binary instances” or a situation where it will take the instantiation of two instances (often of different classes) in order to capture one concept. ...

Dave McComb discusses data lakes, schema, and data-centricity in his latest post on the Data Centric Revolution for The Data Administration Newsletter. Here’s a brief excerpt to pique your interest: “I think it is safe to say that there will be declared...

Data-Centric vs. Data-Driven

by Dave McComb | Sep 21, 2016 | Data-Centric Architecture

In this column, I am making the case for Data Centric architectures for enterprises. There is a huge economic advantage to converting to the data-centric approach, but curiously few companies are making the transition. One reason may be the confusion of Data Centric...

Evolve your Non-Temporal Database in Place

by Dave McComb | Jul 1, 2016 | Knowledge Graphs & Ontologies

At Semantic Arts, we recently decided to upgrade our internal system to turn something that was a not temporal (our billing rates) into something that was. Normally, that would be a pretty big change. As it turned out, it was pretty straightforward and could be done,...
