Patrick- There are some things in MODS that are close to addressing this problem, for example you could create a part wrapper around each file, but my reading of the docs says that may not be the intended use of the part element (depending in part on whether the files represent different physical objects or not). The other strategy used to coordinate elements in MODS is the altRepGroup attribute (where the location, physicalDecription and accessCondition elements for one file would all get the same altRepGroup attribute value). But that seems to be for multiple versions of the same content (e.g., titles in different translations/etc., internal note and link to external HTML version of the same note, etc.), which doesn't necessarily seem like a good fit here. But you may be able to use one of those strategies. At UC San Diego, we use our own locally-developed model, based in part on MODS. One of the things we've added is a component class within a digital object to handle any kind of structure, including multiple files, nested hierarchy, etc. When we export to METS, we would make one MODS record for the object, and then a separate MODS document for each component, and then link them using the METS structmap. To stay completely within MODS, you could also use relatedItem to link multiple MODS records. For a better encoding of the restrictions and embargo dates, you may want to add PREMIS, which has a better vocabulary for describing those things. -Esme -- Esme Cowles <[log in to unmask]> "Necessity is the plea for every infringement of human freedom.

In particular I wonder how best to express the different access restrictions on digital files when a record contains more than one full-text file.
