I've resolved this by instantiating CenteraXUID instead of XUID. 

Now the question is how do I determine programmatically whether to instantiate a CenteraXUID or XAMXUID?  What is the difference between the 2?

We are going to have a documents stored via Centera SDK and via XAM, and wil need to retrieve both via the same application.

Within a XAM application, ideally you should not do anything that is Centera specific. However, if you require to pull back "traditional" Centera Content Address data, then you can use the CenteraXUID to do this.

The Centera Content Address is a 27 or 53 character string, with the 14th character always being being 'e' e.g.

0RLBIE2MP79JQe11RBFG9NCEP46

A XUID is a binary / byte sequence value which can also be represented as a Base 64 encoded string e.g.

AAAEcwA9KK1BOE1ST0JTS0VGNzBHZTlOTUsxR0tRMkxIOUFHNDE0QkZOM0oxQzFKNk44NEEwQ1VCVVRJNg==

Testing for the length of the data and the presence of the 'e' will let you know if it is a ClipID rather than a XUID if your application does not store any other form of indicator within your database.

Be aware that when you open a Centera clip using XAM, you will get back a "translated" representation of the Clip as an XSet. Also, if you commit this XSet representation (even without making any changes) then this will resuly in this new XSet representation being persisted on the Centera XSystem Centera i.e. a new XSet s created and any underlting content is now protected by the old Clip and the new XSet. Both would have to be deleted before the content would become eligible for Garbage Collection.

Thank you for the information.

Hi,

I am using the .Net wrapper for RetrieveContent, and I have the ClipId, is there a way I can map this ClipID  to XUID? Using XUID the retrieval of image is faster.
