ONKI Light is a SKOS vocabulary browser that can be used by content
indexers and information seekers to search for vocabulary concepts and
terms. It is built as a web application on top of a standard SPARQL
endpoint. In addition to the web interface, it provides a REST API for
machine access as well as RDF / Linked Data download access to individual
concepts and whole vocabularies.
See the ONKI Light demonstration
for a list of available vocabularies and to try out the user interface.
The ONKI Light software (PHP web application) including the source code
and documentation (in the wiki) is available at the project page on Google
The software is distributed under the MIT license.

The Finnish Ontology Library Service ONKI was published as a living laboratory prototype for public use in 2008. Its idea is to support content indexers and ontology developers via a browser interface and machine APIs. ONKI has been well-accepted, but being a prototype maintained by the ending research project FinnONTO (2003–2012), a more sustainable service was needed, supported by permanent governmental funding. To achieve this, ONKI was deployed and is being further developed by the National Library of Finland into a new national vocabulary service Finto. We discuss challenges in the deployment of ONKI into Finto and lessons learned during the transition process.
