4.1.3 Recognition and parsing of SIPs
4.1.3 - The repository shall have adequate specifications enabling recognition and parsing of the SIPs.
Definition of SIP describes the structure and content of the two types of SIP in use by the CLOCKSS archive. Definition of AIP describes the process of parsing these two types of SIP into the single type of AIP in use by the CLOCKSS archive, an Archival Unit (AU). It describes the role the publisher plugin, a customized instance of a Java class that is at attribute of the AU, plays in this process. In effect, the plugin is an executable specification of the AU and the SIPs that provide it with content. The Harvest Plugin Development and Testing section of CLOCKSS: Ingest Pipeline describes the process of creating this specification for a particular harvest publisher's SIPs, and the File Transfer Plugin Development and Testing section of CLOCKSS: Ingest Pipeline does the same for a file transfer publisher.
