			After reading [http://ndsr.nycdigital.org/check-your-aip-before-you-wreck-your-aip/ Dinah's great blog post] I realized what I think might be best would be if the OAIS recongised that representation information is made up of data objects and that the only difference between those data objects and others in an AIP is that they may be shared with other AIPs but otherwise need to be preserved just as much as the other data objects do.
			The benefit of this is that the OAIS would recognise that information objects cannot exist without the representation information (at least when that RI is software) and that therefore the representation information should be considered to be of the same importance as the other data objects in any AIP. Right now it implies that the representation information is less important than the other data objects in an AIP.

			And I do think that every object in an OAIS should require software to be provided with it. Without the software you can't interact with the information object so you haven't preserved it. I think the interesting consideration should be whether the software has to be within the AIP or just referenced by the AIP. I can see representation information being used to reference other AIPs that include the software. I suspect others believe this also. For example, Ex Libris Rosetta basically assumes this requirement to have the software available as it assumes that an object is at risk only if there is no software available to interact with it.
			In summary, I think software should be considered a first class object in the OAIS just like the current "data objects" are. It is as important to an information object as the current "data objects" are so why do we relegate it to an effective after-thought?

	I'm very much in favour of recognising the importance of software in digital preservation (and for preserving software to enable data preservation for that matter), but I'm not sure I understand the motivation for this proposal. What benefit does this change bring, and why is it a problem currently?
