CLARIN Technology

The technical pillars of the CLARIN infrastructure are:
  • Federated Identity: letting users log in to protected data and services with their own institutional login and password
  • Persistent Identifiers: enabling sustainable citations of electronic resources
  • Repositories: digital archives where language resources can be stored, accessed and shared
  • Component Metadata and concept definitions: to ensure semantic interoperability when describing language resources
  • Content Search: offering a search engine for a wide range of language resources
  • Web service chaining: giving users the possibility to freely combine language processing services.

The Services section gives an impression of how all these technological components are combined into ready-to-use packages for our scientific community.



CLARIN is based on a distributed network of organisations (or centres) that host language resources and related services. These centres each have their own expertise. Within a single country they are often grouped into a national consortium.

Each consortium has appointed one centre as a representative in CLARIN's technical body, the Centre Committee. This is where most of the technical work happens: writing specifications, planning software development and organising the quality control for each of the centre candidates. The independent Center Assessment Committee analyses each of the candidate centres and provides feedback with regards to compliancy to the technical and organisational requirements.


CLARIN for Programmers

As a programmer, how can you use and contribute to CLARIN's infrastructure? Read about Open Source Code, APIs, Widgets and Notebooks on our CLARIN for Programmers page. 

You are also welcome to join our mailing lists and chat channel, to talk about ideas and issues or to brainstorm about future plans! Or meet us at one of the yearly centre meetings.
