Most data comes from closed-world systems — forms, sensors, logs — with known schemas. Yet the RDF community often says: adopt the full semantic web stack or nothing.
My latest post explores practical RDF for closed-world systems:
- When closed-world makes sense
- Real examples: sensors, IoT, forms
- How Netflix uses RDF+SHACL at scale
- New SHACL 1.2 features

Bringing Semantics to Closed-World Systems

The origin of most data in the world comes from closed-world systems. Forms, logging systems, and sensors all generate data in predefined structures where the schema is known in advance. Yet when peop

In this blog post at https://s.gwdg.de/m5Bu3L I showcase the #NFDI4BIOIMAGE (@nfdi4bioimage, @[email protected]) #knowledgegraph and its function as a registry for public #OMERO image data repositories and their respective #SPARQL endpoints. Annotated #bioimage data has become part of the #semanticweb. @joshmoore @Andrawaag #nfdi #metadata #KnowledgeGraphs #ontop #r2rml #rdf

Linked Open Data for Bioimaging

This post demonstrates the NFDI4BIOIMAGE Knowledge Graph (N4BIKG). Many aspects of this project are still very much in the flow including a consensus on which ontologies and terms to employ, how to define various namespaces and much more. These issues left aside, I focus on two components: First, the "core" KG contains information about the NFDI4BIOIMAGE consortium, it's participating institutions and people working in or for NFDI4BIOIMAGE, publications (via zenodo records submitted to the NFDI4BIOIMAGE community) and some more.

I love when a guy sits his #asshole down #ontop of my #cock & rides me like a cowboy, with both of us doing an equal amount of the work, me thrusting up & him bouncing his asshole up and down tightly around my cock. But I especially love when he's a petite guy who I can lift up like this on top of my cock, or even better yet, with him riding my cock while I'm standing, holding him up. I don't get this often, but I adore a petite lover like this, especially when he is #young & a #gay #Twink.

Linking metadata in electronic lab notebook #OpenBIS with metadata in the
#bioimage resource #Omero: How many images are present in omero for a given sample in OpenBIS?
At #mpievolbio, to answer this and similar questions,
we map both resources to #RDF #KnowledgeGraphs using the #ontop framework,
serve the materialized #KGs via #qLever (https://qlever.cs.uni-freiburg.de) and run a #SPARQL query. Answered in no time! @nfdi4bioimage #LinkedOpenData #FAIR #MicrobialPopulationBiology @ontop
