[smila-user] Persistent unique IDs in SMILA

[Bjoern Decker <bjoern.decker@xxxxxxxxxxx>]

Dear SMILAs,

 

Within the CUbRIK platform, each content object gets an persistent unique ID for identification.

This ID has the following requirements:

1.     It needs to be unique for an instance a CUbRIK platform or even better, worldwide. (The ID is used to allocate the content object within the CUbRIK platform.)

2.     It needs to be calculated locally on a node, i.e., with no central component that provides these IDs.

3.     It needs to be unique across job runs

4.     For the same object (from the same location with the same metadata) it should be the same

 

 

Initially, I came up with the following solutions

a)     Use the record ID created during job runs (does this fulfill 3.??)

b)    Use the fingerprint from delta indexing (Does this fulfill 1?)

c)     Creating a hash from the document metadata (which might be the same as b)

d)    Use GUIDs (however, this would not satisfy 4.)

 

But maybe you have a better suggestion for this.

 

Best wishes

 

Björn
