I'm wondering if we can make a split, so the relevant parts of the >manifest can be stored for later reference. Something like the following: I have another proposal for this. Motivation: The manifest will be processed by different entities that will differ in processing capability. We want to make it easy to include potentially complex information in the manifest, without having to burden lower-resource entities that don't need to process this information. The goal is to make the manifest format more generally processable. Proposal: Assocate with each entity in the manifest additional information describing the audience for that information. One way to do this would be to change the top-level of the manifest to something like: Manifest = [ manifestVersion: 1, digestInfo: DigestInfo, sequence: SequenceNumber, info: { * int => bstr } ] This would be similar to how extensions are handled, except that all of the existing instructions would be formatted in the same way. A given entity would know the fields that it is able to process, and any other fields it can simply skip (as it is just a bstr). This adds some complexity to the normal processing, and it would be important to require, for example that the entries in 'info' are in order by key in order to have a canonical representation. David
