Valid IP for CSIP: valid_IP_with_SHOULD_MAY_1_rep

[koit]

This issue is to document valid_IP_with_SHOULD_MAY_1_rep.

valid_IP_with_SHOULD_MAY_1_rep is a minimal IP with one representation that fulfils all MUST, SHOULD and MAY requirements of CSIP. "Minimal" refers to the attempt to meet the requirements with the least amount of complexity, e.g. have only a single payload file, only one representation and only the package level METS file.

Thus, by definition, it does not meet CSIP105-CSIP112 that require multiple representations and CSIPSTR12 that requires a representation-level METS file.

As of 2021-07-04, the validator at https://pyip.openpreservation.org/validate/ reports 4 Schematron issues:

ID	Level	Location	Validator message	Comment
CSIP21	Warn	mets/dmdSec/mdRef	SHOULD provide a reference to the descriptive metadata file located in the “metadata” section of the IP..	There are two of these warnings, one for each dmdSec, and both are erroneous, as there are dmdSec/mdRef elements that properly reference the metadata files.
CSIP114	Error	mets/fileSec/fileGrp [@USE='Representations']	A pointer to the METS document describing the representation or pointers to the content being transferred must be present in one or more file groups with fileSec/fileGrp/@USE attribute value “Representations”.	This is a wrong interpretation of CSIP due to ambiguous wording. The matter is discussed at DILCISBoard/E-ARK-CSIP#642.
CSIP101	Warn	mets/structMap/div/div [@LABEL='Representations']	When no representations are present the content referenced in the file section file group with @USE attribute value “Representations” is described in the structural map as a single sub division.	This warning is undue as the package does have a representation.
