In many areas of scholarly work, controlled vocabularies (gazetteers, thesauri, etc.) play a crucial role as a stable reference for resources and for ensuring interoperability between disparate projects and their data. The ACDH-CH provides services and tools that allow for collaborative creation, maintenance and publication of vocabularies and taxonomies of any kind.
Vocabs browse service is based on the open-source software Skosmos, which uses SKOS as the underlying data model. Skosmos offers browsing of vocabularies with structured concept displays and visualisation of concept hierarchies. Vocabularies can be searched with a search interface or by consulting an alphabetical or thematic index. Vocabularies can be accessed via a REST-API, to allow for Linked Data.
Vocabs services does not only serve controlled vocabularies for ACDH-CH purposes, but is also employed as a service for partners of the national CLARIAH-AT consortium, for the Thesaurus Maintenance working group in DARIAH-EU, and in general as a service of DARIAH-EU where it can also be accessed at https://vocabs.dariah.eu.
Vocabs editor is a web-based tool for collaborative work on controlled vocabularies development.
The editor follows the SKOS data model for the main elements of a vocabulary. The Dublin core schema is used to capture the metadata (such as date created, date modified, creator, contributor, source and other) about each element. Each concept scheme as well as each individual concept can be downloaded in RDF/XML and Turtle format.
The user management system allows a user to share a concept scheme she/he created with other users (called 'curators') to create new, edit and delete concepts and collections within this concept scheme. Each user can find a summary of their latest activity on user's page. The tool also provides API to retrieve the data.

Vocabs visualize service is in ongoing development. The service aims to allow for viewing multiple concept schemes and relationships among their concepts.
SKOSMOS provided API to connect projects’ web applications to published vocabularies. Visit API swagger documentation
