4.4.3 Namespace fingerprints
For each namespace, there is an associated namespace fingerprint. Since namespaces will usually be short strings, and since there might be people who choose the same namespace or simply used the proposed default (DSY), some additional verification is needed to assure that two namespaces are really the same. For this purpose, each namespace name is associated with a fingerprint. The namespace fingerprint is typically a longer random generated string.
The repository server keeps a table of the namespaces used in the repository and their corresponding fingerprints (these are the namespaces that are said to be registered in the repository). The registered namespace are viewable through the administration screen of the Daisy Wiki, which also allows unregistering unused namespaces.
For export/import, namespace fingerprint information is included in the export, so that it can be verified upon import.
