This is about a type and a value of the idenfifier for "linkingAgent" (the user that triggers the event), linkingObject (the object the event ocured for), and the event itself.
For agent and object we see two possibilities:
- type: escidoc system identifier (a URI should be found), value: 'escidoc:123'
- type: URL, value: '/ir/item/escidoc:123'
Remarks: Case 1 will not fullfil the premis requirement designation of the domain in which the [...] identifier is unique except the identifier type identifies the specific installation/instance of the eSciDoc Infrastructure. For case 2 a base URI must be provided or the value must be an absolute URI instead of an absolute-path and the URI may change in the authority part by configuration of the eSciDoc Infrastructure (cf. RFC 2396, 3. URI Syntactic Components, 5. Relative URI References).
For the event identifier type and value there is the possibility to use the XML ID of the event (xpath: premis:event/@xmlID) or to create a PID when writing a new event. The latter seems to be to much effort for that case. Frank 14:39, 15 April 2010 (UTC)
