Related to our approach to represent and to query lists as composite values in RDF-based Knowledge Graphs, I developed a tool to convert RDF files in which lists are represented as RDF collections (rdf:List) into files that use our cdt:List approach.

So far, declarative mapping languages for knowledge graph construction (RML and the likes) have lacked a solid formal foundation 😶‍🌫️

⚡ Our #ESWC2025 paper changes that: We introduce an algebra for mappings, provide a formal semantics of RML, and more.

The standards process is never quick. Getting consensus from a wide community takes time and diligence. This one has been talked about for *decades* but the actual standardization process was pretty quick. Finally: RDF Canonicalization is a W3C Rec https://t.co/wjRzLk8mCX

This is not a drill. Linux users must check their xz installations

A remote SSH-based backdoor has been found in the widely used data compression library and tool, and has made its way into public distributions, including recent Fedora and Kali Linux

@neumarcx @kinow Nothing supports zip or tar files ATM - contributions welcome. Compression is supported, both via HTTP Content-Encoding (gzip) and .gz files. The loaders support multiple files, each of which can be compressed.

Just missing the tests now, but soon Jena Fuseki UI will have improved pagination for people with a lot of datasets/graphs 👍🤺 https://t.co/i5nsCrvfzB #opensource #javascript #VueJS #UIUX #TheASF #SemanticWeb

If Computer Science Is Doomed, What Comes Next? After 50 years of programming, we humans still suck at it. "And I don't think another 50 years is going to solve it," Fixie co-founder Matt Welsh tells Harvards CS50 class. See it on YouTube. #AI #LLM #CS

Just been thinking about how the UK AI Safety Institute might practically play out.

It is difficult for costly organisations set up in the dying days of Government, and closely associated with the Prime Minister, to survive the transition to a new administration.

@wohnjalker @namedgraph @thejustman They are normative in JSON-LD 1.1 - outside JSON-LD a datatype being normative means "this is the definition". Current work on rdf:JSON is https://t.co/rRPFFAaANp and associated PR
