Annotation batches track source data for the whole annotation endeavor. Smaller selections of the AAPB collection are chosen and cataloged as batches in this directory.
A batch is the set of identifying GUIDs/tags for a group of media assets from the AAPB collection. These sets are chosen for a variety of reasons, but are typically designed to help evaluate or improve CLAMS applications.
An AAPB GUID is a unique identifying string that can be used at the AAPB website to find one particular media and its supporting files. For example, cpb-aacip-96d289b264c can be accessed at https://americanarchive.org/catalog/cpb-aacip-96d289b264c.
The AAPB GUID is not a Universally unique identifier; it is unique only within the scope of the AAPB.
Batches precede annotation projects, but some batches may be created just for the purpose of a single annotation project. Annotation projects then choose appropriate batches to structure the work.
See the projects directory for annotation projects that use these batches.
