SOCH (Swedish Open Cultural Heritage) is a web service used for searching and retrieving data from museum an historical environment sectors in Sweden.
SOCH aggregates metadata from different central, regional and local databases in order to facilitate applications to search and present cultural heritage data via an open API.
A number of museums are also building applications on SOCH in order to make more than their own stuff available online.
In 2012 commercial applications started to appear using SOCH data.
The SOCH is operated and developed at the Swedish National Heritage Board (SNHB).
