Purpose

The purpose of this page is to collect relevant information about the CLARIN Language Resources Switchboard.

Project: Language Resource Switchboard

The CLARIN Language Resource Switchboard helps users to connect language resources with applications that can process them in one way or another. With the switchboard, users shall be able, for example, to perform linguistic analyses (for text data), OCR (for scanned images), or speech recognition (for sound recordings) on data found in the VLO, FCS, or VCR. There is also a standalone version of the switchboard where users can upload their own resources via file upload, URL input, or simple text entry.

The switchboard is seen as a technical vehicle to match language resources (described by CMDI metadata) with applications that are registered to the switchboard via an application metadata description. Note that the switchboard is not a workflow composition engine (like e.g. WebLicht?), and also that the switchboard is not storing or maintaining any data in connection with the matching service (analysis results, provenance data etc.).

History

• development was initiated during the CLARIN-PLUS project. The first main development phase lasted 18 months (03/2016-08/2016).
• In cooperation with the EUDAT project, the B2DROP-switchboard Bridge was initiated. It is envisioned to make available the bridge to all B2DROP users at ​https://b2drop.eudat.eu.
• In cooperation with the PARTHENOS project, the switchboard is being hooked up with the D4Science platform, see ​https://parthenos.d4science.org.
• In 2018, the file storage server was changed from the MPG Garching location to a locally-installed Nextcloud instance.
