Splitting

[kuldaraas]

the splitting part needs to be updated!

[andersbonielsen]

The splitting is based on the METS file pointing to other METS files using METS pointer elements in the structMap.
This approach allows the IP to be split into more or less independent (if not autonomous) sub-IPs that can be stored on seperated media and validated independently.

[andersbonielsen]

As "the Information Package folder CAN be compressed (for example by using TAR or ZIP)" (according to 4.1, page 25) we are also considering to let the splitting be handled by TAR or ZIP. Note, that this method will require lots of unified space for large IP as they will have to be split and merged as a whole (e.g. splitting a 5 TB IP requires 5 TB space for merging it.)

[andersbonielsen]

New version of splitting IPs is being created. Relates to the use of METS in representations.

[andersbonielsen]

The textual description will be added to the segmenting_ip branch.
The affected file is expected to be:

Editing and reviewing section 6.2

• Need to update references
• Need to aligne use of ID

Too early to close issue

[carlwilson]

We're not sure about progress here and there are some thoughts on splitting packages in the new AIP specification and the SIARD CITS. It's too late to consider a detailed approach in any release for October 2021, but perhaps some guiding text/thoughts can be added from accumulated wisdom. @carlwilson to check.
