Last Call: SPARQL 1.1 Query Language

24 July 2012
The SPARQL Working Group has published a Last Call Working Draft of SPARQL 1.1 Query Language. RDF is a directed, labeled graph data format for representing information in the Web. This specification defines the syntax and semantics of the SPARQL query language for RDF. SPARQL can be used to express queries across diverse data sources, whether the data is stored natively as RDF or viewed as RDF via middleware. SPARQL contains capabilities for querying required and optional graph patterns along with their conjunctions and disjunctions. SPARQL also supports aggregation, subqueries, negation, creating values by expressions, extensible value testing, and constraining queries by source RDF graph. The results of SPARQL queries can be result sets or RDF graphs. Comments are welcome through 21 August. Learn more about the Semantic Web Activity.

  The Ultimate Guide to Being Cited by Google AI Overviews, ChatGPT, Perplexity & Gemini In 2025, getting ranked on page 1 of Google is no longer enough. You now need to be the source that AI engines cite in their answers. Google’s AI Overviews already appear on more than 17-25 % of queries (depending on region), Perplexity is growing 300 % YoY, and ChatGPT Search is live. If your content isn’t structured in a way that large language models can easily parse, extract, and trust, you simply won’t appear in the new generation of search results.

ChatGPT Atlas - The Evolution of Search: From Links to Conversations

Image
In the ever-evolving landscape of web browsing, OpenAI's ChatGPT Atlas has emerged as a bold challenger to the status quo. Launched on October 21, 2025, for macOS (with Windows, iOS, and Android versions teased as "coming soon"), Atlas isn't just another Chromium-based browser—it's an AI-infused portal that reimagines how we discover, process, and act on information. At its core lies a transformative search engine powered by ChatGPT, blending conversational AI with traditional web queries to deliver results that feel less like a list of links and more like a thoughtful dialogue with the internet. As someone who's spent hours tinkering with Atlas (and yes, I've imported my Chrome extensions for that seamless switch), I can say this: search in Atlas isn't about replacing Google—it's about elevating it. Gone are the days of sifting through blue hyperlinks; instead, you get curated insights, multimodal tabs, and an optional "memory" that rec...
