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 to participate you are welcome to join. lotico develops and promotes standards, and cooperates closely with standard groups in particular with regards to Semantic Web technologies and data on the web.

Data Shapes with Jose Emilio Labra Gayo and Eric Prud’hommeaux
A Collaborative Management System for OWL ontologies, SKOS(/XL) thesauri, Ontolex-lemon lexicons and generic RDF datasets
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.
A workshop on geospatial semantic data for the web
Learn about SPARQL evaluation semantics and some of the main algorithms used for processing SPARQL queries, such as joins.
about time for an update on all things JSON-LD with Gregg Kellogg in September 2020
The Many Shapes of SHACL with Holger Knublauch in June.
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.
An update on ongoing work on geospatial support in RDF stores and the GeoSPARQL implemenation.
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.
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 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.
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.
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.
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.
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.
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.
A conversation with Andy Seaborne about Jena, SPARQL, TDB and RDF at scale recorded live at the Lotico Semantic Web event in San Francisco
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.
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 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.
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.
Kate Ray has independently produced a short story about the Semantic Web
