29 | | At '''import''', when the system receives a resource with a prefixed UUID and the prefix matches |
30 | | the domain of the current instance, then the prefix gets removed to identify the resource |
31 | | in the database. If the prefix differs from our domain, then the prefix is retained in the |
32 | | database record. |
33 | | |
34 | | At '''export''', all unprefixed UUIDs from the database get prefixed by the domain name of the |
35 | | current instance. In those UUIDs which already have a prefix (because they have been imported |
36 | | from another domain), the prefix is retained. |
