What we're about

Meet local people interested in standardized and future (Semantic Web) Internet technologies aimed at turning the Web into a huge repository of cross-referenced, machine-understandable data and executable artifacts, processes and services. We envision and debate how the emerging social, semantic, pragmatic, multimedia Web mediates the ways in which we construct mutual understanding, shared meaning, and knowledge-based collaboration. We address Semantic Web / Web X.0 technologies and applications that help to develop or that use ontologies, controlled vocabularies and rules systems on the public World Wide Web and in the enterprise - as Corporate Semantic Web with valuable business models behind it. The Berlin Semantic Web Meetup group provides common ground for dialogue at the nexus of these topics. WE INVITE YOU as a practitioner, decision maker or researcher working on these challenges or having an interest to join us in the Meetups to share your work, and to come and find out what others are doing. This is an emerging network of people exploring the intersection of established intellectual traditions and the fast changing Web: come and help shape the community!

Describe and Validate Your RDF Data with Data Shapes

RDF is a fundamental part of the web (championed by the semantic web and knowledge graph efforts). It has a versatile data model that enables automatic integration of data from different sources. The RDF ecosystem supports systems which can be available through SPARQL endpoints as well as knowledge representation languages that can be used to infer new data. However, RDF versatility also comes with a price and it is necessary to adopt defensive programming techniques when confronted with it. Although RDF producers usually have an implicit schema of the data, it is not explicitly documented nor is it rigorously followed, requiring consumers to program defensively or write elaborate queries to work around inconsistencies. Shape Expressions (ShEx) has been created as a concise and human readable language to describe and validate RDF data. ShEx schemas declare expectations about the topology of RDF data which can be automatically verified. ShEx is used in large-scale modeling efforts like FHIR and Wikidata. For instance, Wikidata Entity Schemas extensions create a whole ecosystem of ShEx schemas and it has also been increasingly adopted by the community. In this talk, we will describe the language and some of its applications and tools.
