17.10.3 The Packaging Component
The CASPAR Packaging software component is a Java API based closely around
OAIS concepts, and exposes operations that provide for the general management
of AIPs as identified in the CASPAR User Requirements document [
206
]. The
packaging components main responsibilities are:
- Construction
- providing operations to build AIPs conforming to OAIS stan-
dards.
- Unpackaging
- providing access to the internal information objects or resolvable
references to information objects if they are external to the package
- Validation
- providing operations to validate the contents and structure of an AIP
- Transmission
- providing operations to send an AIP to a location for storage
- Storage
- provides operations to store packages by calling PDS.
As XFDU was chosen as the default AIP format, CASPAR implemented the NASA
XFDU Java based toolkit [
148
] to provide construction, unpackaging and validation
