DCAF 2020: Second Annual Data-Centric Architecture Forum Re-Cap
by Semantic Arts | News & Community
Last year, we decided to call the first annual Data Centric Architecture Conference a Forum which resulted in DCAF. It didn’t take long for attendees to start calling the event “decaf” but they were equally quick to point out that […]
Decades, Planets and Marriage
by Michael Uschold | The Whiteboard
Google ontologist, Denny Vrandečić started a vigorous thread on the question of what constitutes a decade. See for example, the article: “People Can’t Even Agree On When The Decade Ends”. This, is a re-emergence of the question from 20 years […]
Meaning-First Data Modeling, A Radical Return to Simplicity
by Dave McComb | Knowledge Graphs & Ontologies
In brief: Meaning-First data modeling stores data as triples, each a subject, a predicate, and an object (such as Person uses Language), with formal definitions that let software reach the same conclusions a person would. The W3C standards RDF and […]
Time to Rethink Master and Reference Data
by Semantic Arts | Data-Centric Architecture
In brief: Master data and reference data are both core entities, and this post argues they differ in how they flow, not in what they are. Reference data, such as countries or units of measure, is curated centrally by an […]
The Data-Centric Revolution: Semantics and the DAMA Wheel
by Dave McComb | Data-Centric Architecture
Asked which wedge of the DAMA wheel semantics changes most, Dave McComb works through the wheel one wedge at a time. Knowledge graphs and a data-centric approach change data modeling, integration, metadata, and architecture far more than the DMBOK allows.
Facet Math: Trim Ontology Fat with Occam’s Razor
by Dave McComb | The Whiteboard
At Semantic Arts we often come across ontologies whose developers seem to take pride in the number of classes they have created, giving the impression that more classes equate to a better ontology. We disagree with this perspective and as […]
Property Graphs: Training Wheels on the way to Knowledge Graphs
by Dave McComb | Knowledge Graphs & Ontologies
In brief: A property graph, also called a labeled property graph, is a graph database that can hold values on its edges as well as its nodes. That’s the main difference from an RDF knowledge graph, which attaches values through […]
When is a Brick not a Brick?
by Dave McComb | Data-Centric Architecture
They say good things come in threes and my journey to data-centricity started with three revelations. The first was connected to a project I was working on for a university college with a problem that might sound familiar to some […]
Toss Out Metadata That Does Not Bring Joy
by Dave McComb | The Whiteboard
As I write this, I can almost hear you wail “No, no, we don’t have too much metadata, we don’t have nearly enough! We have several projects in flight to expand our use of metadata.” Sorry, I’m going to have […]
My Path Towards Becoming A Data-Centric Revolution Practitioner
by Dave McComb | Business Case & ROI
In 1986 I started down a path that, in 2019, has made me a fledgling Data-Centric revolution practitioner. My path towards the Data-Centric revolution started in 1986 with my wife and I founding two micro-businesses in the music and micro-manufacturing […]
The Flagging Art of Saying Nothing
by Semantic Arts | Knowledge Graphs & Ontologies
Who doesn’t like a nice flag? Waving in the breeze, reminding us of who we are and what we stand for. Flags are a nice way of providing a rallying point around which to gather and show our colors to […]
The Data-Centric Revolution: Lawyers, Guns and Money
by Dave McComb | Business Case & ROI
My book “The Data-Centric Revolution” will be out this summer. I will also be presenting at Dataversity’s Data Architecture Summit coming up in a few months. Both exercises reminded me that Data-Centric is not a simple technology upgrade. It’s going […]
