We are also implementing PREMIS within a hierarchical database and have addressed the issue of relationships by creating a table to record relationships in line with PREMIS. Information on this is attached.
We will record all metadata within the database, with the address of original objects, SIP metadata and transformations recorded therein.
I would be interested to know what others think of this approach.

Subject: [PIG] AW: [PIG] Upcoming revision of the PREMIS Data Dictionary - call for participation
We've just been discussing a similar question, so thank you Youn for bringing this up!
We decided to use PREMIS to record metadata in a digital preservation project with state archives in Switzerland. I should point out that this is really a very basic, pilot project, and that we are not using METS, which may be the cause of some of the problems we encountered. Namely, we are archiving data from a database-driven application. We plan to combine several plain-text data files, information about the data model, and other files into a zip-file. So we have a representation (the AIP in the current form) consisting of one file (the zip-file) which itself consists a couple of other files - there clearly is a hierarchy of files that is difficult to model in PREMIS. Example 3 in the PREMIS Data Dictionary (p. 3-34 sqq.) gives a hint of how to achieve this, namely through the use of the "relationship" semantic unit. However, this looks more like a workaround to me, as I understand a file cannot contain other files. Is this understanding correct? Or am I missing the actual point here?
Thanks for any kind of clarification.
Best,
Georg
