The HuNI data service is part of the Humanities Networked Infrastructure (HuNI) vitrual laboratory. It is responsible for harvesting from partner feeds, storing the harvested aggregate data, and transforming it for ingest into the HuNI data stores. It provides an API into the aggregate data store for reporting on harvest status and for returning stored documents.
More information can be found on the primary HuNI site. For technical information regarging HuNI infrastructure start at the technologies page.
The harvest REST API is specified as a OpenAPI v2 document. It is publically avaliable via the huni-harvester bitbucket repository.
Note that a dynamic API explorer is also avaliable.
