Most of our work is open-source and available on GitHub.

Here is a short selection of our FOSS work, featuring different types of our open-source projects and open-source contributions:

RDFJS

In 2013, Zazuko initiated the W3C RDF JavaScript Libraries Community Group. This group discusses specifications for and implementations of libraries for working with RDF and Linked Data in ECMAScript platforms such as Web browsers and Node.js.

Our Zazuko CTO Thomas Bergwinkl is co-chair of the group and several Zazuko employees are core-contributors to the RDFJS specifications and reference implementations.

rdf-vocabularies

Vocabularies in the wild, even the most commonly used ones, are not always easily accessible.

@zazuko/rdf-vocabularies is an NPM package providing a list of what we define as common prefixes & vocabularies. It contains tens of common vocabularies and thousand of triples as N-Quads. Bonus: You can get a RDFJS Dataset back containing triples of this vocabulary! It is also very useful when you want to resolve prefix:term to the corresponding IRI or the other way around.

Zazuko Prefix Server (repo) is built on top of @zazuko/rdf-vocabularies.

openlayers-elements

Map Web Components, implemented using v5 of OpenLayers library.

@openlayers-elements/maps provide a high-level wrapper over OpenLayers which makes it very easy to add fully-featured maps to any web application. By taking advantage of latest custom elements specification, the maps can be combined with any web library.

Additionally, @openlayers-elements/swisstopo package adds ready-made layers from the Swiss Federal Office of Topography.

d3-sparql

d3-sparql is a plugin for the popular D3.js data visualization library. After configuring a SPARQL endpoint and a SPARQL query, it produces data in a format that is easily consumed by D3 to generate great visualizations.
