The Arca Sandbox is a space for local administrators to test configurations, ingests, settings, new modules, etc. without affecting their live repository in Arca. This site is a clone of Arca, with the same Solr fields available, the same theme, and the same set of modules (with a few extras thrown in for testing).
If you are an Arca local admin and want an account in the Sandbox, send an email to the Arca Office.
Objects ingested here are not automatically deleted, but might be purged periodically depending on storage needs.
