From discussion of issue 13 the need to model sequences of physical and conceptual objects also need to be added to the issues list. This could include page numbers, periodical series, acts in a play etc.
Proposal to be compatible with METS.
The METS schema uses a series of nested DIV elements to represent compound digital objects. The DIV elements have an ORDER attribute, used to record an integer representation of the DIV's order with respect to it's siblings. I propose that we model ORDER as a specialization of E54 to the CRM.
However, since sequences can apply to both physical objects (e.g. folios in a manuscript) or information objects (e.g. sequences of digital page images), this proposal would require the domain of P43: Has Dimension to be promoted from E18: Physical Stuff to it's superclass, E70: Stuff.
N.B. The scope note for property P43 (CRM v3.3.1) is compatible with this proposal, although it needs to be copy-edited for grammar.

Alternatively we could interpret the ORDER as a specific identifier, an Appellation of parts? Neither that would require a change. This is consistent with regarding spatial coordinates as identifiers.
To measure immaterial objects seems very reasonable to me, also for playing durations of video etc., seehttp://metadata.net/harmony/MW2002_paper.pdf.
This proposal would require the domain of P43: Has Dimension to
be promoted from E18: Physical Stuff to it's superclass, E70: Stuff.
and P39 measured (was measured by) to E70: Stuff.
