I recently announced that I have joined Ontotext as a full-time Senior Tech Writer. I have admired their free GraphDB triplestore for a long time (for example, I wrote about how well it supports the GeoSPARQL geospatial extension in October of 2020) and I am now learning about all the great capabilities of their commercial products, such as the scalability of GraphDB Enterprise.

I was catching up with my old friend Paul Prescod the other day. We have not only known each other since the early days of XML, but actually before that: “since XML was a four-letter word”, to quote Paul.

The following blog entries give a brief introduction to the RDF data model, the most important of the other W3C standards that build on it, and what people do with those standards:

When I first heard about the AWS Graph Explorer I assumed that it was a cloud-based tool for use with Neptune, the AWS cloud-based triplestore. After I read Fan Li’s First Impressions of the AWS Graph Explorer I realized that you can install this open source tool locally and point it at any SPARQL endpoint you want, so I cranked up Jena Fuseki on my laptop, loaded some data into it, and installed the Graph Explorer.

I recently wondered “could I run a Python script that includes the rdflib library on my Samsung Android phone?” Five minutes later, I was doing it, and about three of those minutes were spent installing Python.

OriginTrail is doing one of the most interesting combinations of blockchain technology and RDF that I have seen. In November I spoke with CTO and co-founder Branimir Rakić.
