Karen's examples in [3] used an XML expression of the "template-and-constraint" idiom of Mikael's Description Set Profile constraint language [4]. The examples in DC-RDF [5] are expressed using RDF/XML and DC-TEXT [6]. In the spirit of re-constructing DCAM "from the bottom up", starting with concrete examples, it would indeed be great if we could work with a notation that is easy to read. The DC-DSP notation uses angle brackets; DC-TEXT uses parentheses; and Karen improvised a "Pythonesque" notation for two examples in in [7] -- "Pythonesque" because Python uses indentation to define sections without the added clutter of brackets. Beyond agreeing on a graphic style, however, we would need to sort out what it means to "use" DCAM constructs in an example. Mikael's style, with DC-DSP [4], was to say that an instance of a Description, for example, is a Description Template which becomes constrained in a specific way. Alistair, in his strawman draft, saw sets of constraints bundled into something he called Resource Profiles. What examples do we want to express? Can we find a simple way to express them?
