Lotico

Welcome to Lotico - an open, distributed community. Augmented by a Semantic Social Network that brings Location, Time, Community and concepts together for You and all our members around the world. featured event: SHACL for the Practitioner with Veronika Heimsbakk November 24, 2025 lotico.com is your gateway to an open community that shares a common interest in Data on the Web and the Semantic Web vision, a common framework for data to be shared and reused across applications, platforms and community boundaries. If you live, work or visit a location with an active community and you are interested in participating, you are more than welcome to join us. Lotico develops and promotes standards, and cooperates closely with standard groups in particular with regards to Semantic Web technologies and data on the web. Events Next Generation RDF and SPARQL Antisocial Behaviour Detection and Mitigation in Online Platforms The Role of Symbolic Knowledge and Defeasible Reasoning at the Dawn of AGI Wikibase Cloud and the SNARC Hub for Name Authority Records Relating to Wales and in the Welsh Language Data Protection, Privacy and Responsible AI FAIR Data Spaces Now! KOMMA Knowledge Modeling and Management Architecture Data Shapes in Action with Veronika Heimsbakk who presents her application of Data Shapes in production. Data Shapes with Jose Emilio Labra Gayo and Eric Prud’hommeaux Your Personal Linked Data Graphs with Solid with Ruben Verborg VocBench with Armando Stellato A Collaborative Management System for OWL ontologies, SKOS(/XL) thesauri, Ontolex-lemon lexicons and generic RDF datasets Metadata for RDF Statements: The RDF-star Approach The lack of a convenient way to capture metadata about RDF triples has been a long standing issue. Such annotations are a native feature in other contemporary graph data models. In recent years, the RDF* approach has emerged to address this limitation of RDF. After RDF* gained traction among both vendors and users of RDF systems, a community group has formed to produce a new specification, now called RDF-star. Semantic GeoSpatial Web A workshop on geospatial semantic data for the web SPARQL Query Optimization with Pavel Klinov Learn about SPARQL evaluation semantics and some of the main algorithms used for processing SPARQL queries, such as joins. JSON for Linking Data: JSON-LD 1.1 about time for an update on all things JSON-LD with Gregg Kellogg in September 2020 The Many Shapes of SHACL The Many Shapes of SHACL with Holger Knublauch takes a look at the Shapes Constraint Language SHACL which is now a well-established W3C standard. Eclipse RDF4J - Working with RDF in Java an event with Jeen Broekstra May 2020. Eclipse RDF4J is a powerful open source Java framework for processing and handling of RDF (Resource Description Framework) data. Jena Spatial, GeoSparql and the GeoSpatial Semantic Web An update on ongoing work on geospatial support in RDF stores and the GeoSPARQL implemenation. Jena-based Components for Building Semantic Web Applications The basics of RDF and SPARQL may seem simple enough at first, but once one starts to develop a prototype, one quickly stumbles upon the same recurrent problems, such as: How can performance be improved by means of query caching? How can we deal with blank nodes? How to deal with result set limits? A session with Claus Stadler April 2020. The Story of Libraries and the Semantic Web Legacy systems reach their end-of-life and libraries are loosing their traditional role of being "information gatekeepers" due to the advent of the World Wide Web. This is forcing organizations to realign their information infrastructure. Wikidata A Wikimedia Project Wikidata is a free, collaborative, multilingual, secondary database, collecting structured data to provide support for Wikipedia, Wikimedia Commons, the other wikis of the Wikimedia movement, and to anyone in the world. Linked Data With Ruby and RDF.rb A hands-on overview to produce, consume and work with Linked Data using RDF.rb and the programming language Ruby. Topics covered include: Understanding the RDF.rb object model, learning how to manipulate, parse and serialize RDF in popular formats such as Turtle, JSON-LD, and RDFa. Create and publish RDF using a Ruby-based web-framework such as Sinatra, storing RDF in various repository, including SQL DBs. Query local RDF repositories using the native SPARQL engine, access and update remote SPARQL endpoints using a SPARQL client. Semantics and Cultural Heritage meet-up at The British Museum The British Museum, in cooperation with Lotico, will host a meet-up on the subject of semantics and cultural heritage in the Museum’s Asian Department Study room. Three talks are planned: Mapping Cultural Heritage Information to CIDOC-CRM, Representing Artist's Archives in the CIDOC-CRM family and Automatic annotation of the Ancient Egyptian Book of the Dead using CIDOC-CRM, FRBRoo and Museum Linked Data. The Working Ontologist Dean Allemang and MarkLogic's Stephen Buxton one of the world's leading web ontologists helps companies to deploy Semantic Web solutions, training, keynote talks, solution planning, technology selection, data conversion, ontology architecture and modeling. And we take a look we'll look at what happens when you add Semantic Technologies RDF and SPARQL to MarkLogic. An Introduction to Linked Data by Sandro Hawke Still one of the best introductions to Linked Data and even the Semantic Web in general. If you are new to the field and interested in practical information this is a resource for you. SmartMobs with special guest Howard Rheingold This year our global Semantic Web event took place in San Francisco with special guest Howard Rheingold. Howard has a long history in online communities and has wandered the cyberspace long before we called it the web. Jena, SPARQL and TDB - RDF at scale, a conversation with Andy Seaborne A conversation with Andy Seaborne about Jena, SPARQL, TDB and RDF at scale recorded live at the Lotico Semantic Web event in San Francisco Linked Data in Watson:Using The Semantic Web To Answer Questions A team at IBM Research is working to build Watson, a computing system that can understand and answer complex questions with enough precision and speed to compete against the best human quiz show competitors. As with the previous AI grand challenge attempted at IBM Research, (playing chess at a grand master level) the principle challenges for machines to achieve expert performance are fundamentally different than for people. Getting started with SPARQL by Bob DuCharme Web inventor Tim Berners-Lee once said that "trying to use the Semantic Web without SPARQL is like trying to use a relational database without SQL." The W3C standard SPARQL query language is getting nearer to its 1.1 release, and more and more people are using it with free and commercial software to retrieve data from public and private sources. RuleML - Where Web Rule Research Meets Industry RuleML is an open international network of individuals and groups from both industry and academia, with shared interests in rules, and rules on the Semantic Web. Semantic Web for Java Developers - Steve Hamby Confessions of a Semantic Web evangelist. The Semantic Web (a.k.a. Web 3.0) is coming ... or, maybe it's already here! CIOs are investing in Semantic Web infrastructure; governments are spending millions on linked open data. So, what is the Semantic Web? How do you get involved? This presentation will answer these questions. Semantic Web Voices Film: Web 3.0 Kate Ray has independently produced a short story about her take on the Semantic Web
