- In this example the root Item has a Persistent Identifier.
Wiki Markup The identifier MUST be an URI. Some repositories can make use of registered URIs, e.g., in the Netherlands the repositories can make use of National Bibliography Numbers. If a repository doesn't have access to registered URIs, UUIDs or TAGs can be used. More information about UUIDs can be found at \[http://en.wikipedia<ac:structured-macro ac:name="anchor" ac:schema-version="1" ac:macro-id="3b6e0177424a1d72-3f7418cd-463446cb-98c0bc0a-29fe7f170d62aab1b933cdda"><ac:parameter ac:name="">_Hlt190750088</ac:parameter></ac:structured-macro><ac:structured-macro ac:name="anchor" ac:schema-version="1" ac:macro-id="f6189d99347f5022-d5a60dd2-449f47bc-b1509180-fb3a21df2aae9138b30154c8"><ac:parameter ac:name="">_Hlt190750089</ac:parameter></ac:structured-macro>.org/wiki/UUID\|http://en.wikipedia.org/wiki/UUID\] and for TAGs the best starting point is [http://www.taguri.org/|http://www.taguri.org/]. TAGs for the repository of Tilburg University could be constructed in the following way. All TAGs start with 'tag:uvt.nl,<year>:<record id>'. <year> is the year that the compound object entered the repository. The URIs for MODS records can look like 'tag:uvt.nl,<year>:<record id>/mods' and the URIs for object files can look like 'tag:uvt.nl,<year>:<record id>/<file id>'.
- The identifiers of the root Item and the second level Item elements SHOULD NOT be equal to the OAI identifier or the DIDL document identifier.
- Identifiers should not change. Different identifier implies a different object.
- The namespace for dii SHOULD be declared in the DIDL tag.
