Filenet Interview Questions.................What is the length of GUID in FileNet CE?

Ans:- Each object stored (including documents, custom objects etc) in FileNet P8 Content Engine repository has a global unique identifier (GUID). GUID is a system generated unique identifier for the object added to repository. These GUID's are used for reference purposes by other FileNet products as well as 3rd party applications. The length of GUID is 36 characters. GUID Example: E9B46C4F-B75C-46BD-87C3-037A38E6BDF3 Regular Expression for a GUID: "^(\{{0,1}([0-9a-fA-F]){8}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){12}\}{0,1})$" In projects where FileNet P8 is only used as document repository, the GUID is send back to the 3rd party application build around those documents through notification after the document is added successfully. 3rd Party application can store the GUID in their own database and use them to retrieve the document and its metadata using MQ or API calls to FileNet CE.
