2. Library users |
| For the statement A on copies the following statements can be generated: \\
1. Two copies of material will be kept \\
2. These two copies will be held in different geographic locations \\
3. For rare material three copies will be kept \\
4. They will be in three separate geographic locations \\
For the statement B on file formats can be generated: \\
5 File formats must have documentation \\
6. Approved file format fro digtised images TIFF and JPEG |
| Statement A is Geographic dispersion of material to minimize risks due to loss of the bits  \\
Statement B relates to File format quality checking for data managers |
| Statement A \\
For normal collection \\
* There must be at two copies
* There must be at two geographic locations \\
For rare collection 
* There must be at three copies
* There must be at three geographic locations \\
Statement B 
* The file format should have documentation
* File format must be of an approved format for the contentset
* The file format should be able to be validated |
| Statement A \\
For content set: digitised newspapers and user community of curation managers \\
* No-of-copies = 2
* No-Geographic locations = 2 For content set: rare digitised newspapers and user community of curation managers
* No-of-copies = 3
* No-Geographic locations = 3 \\
Statement B 
* format documentation quality MUST be COMPLETE
* format documentation availability MUST be Yes
* format validation support MUST be Yes
* format identifier MUST be TIFF |
| These examples haven't produced any overlap and so there is no change. |{column}
{column:width=30}|| Notes ||
| As one of the newspapers is rare and additional preservation activities will be undertaken, then this should be a content set in its own right.  \\
Therefore 2 content sets have been identified |
| It is not clear from the information provided whether there are further restrictions/differences between student, teaching staff and researchers. There  might be access restrictions to specific journals as a result of publisher's requests, but these are not described in the example. |
| The first statement is fairly self-explanatory, although for the third copy it is not explicit about wherher this implies a third geographic location, for the purposes of this example we will assume that it does.  For the second one, the local meaning of "well understood" has been related to documentation on the file format and the information in appendix A (not shown in the example) has been explicitly stated. |
| The control policy preservation cases are related to planning preservation cases and risks, the two risks being mitigated are, at a high level, bit loss and unreadable/unmaintainable file formats.   \\ |
| | {column:width=10}{column}
| To be able to generated machine readable control statements there needs to be a common vocabulary to ensure that the tools and the user mean the same thing by the vocab used.  SCAPE project used an internal vocab for this work. |
| With a larger policy there might be overlap between policy on metadata and access for example and it might mean that the same objectives are generated for different parts of the policy. |{column}
