Hi Vincent, Great question. We are thinking about a very similar use case and have identified an extension to the CIDOC CRM (the inference extension http://www.cidoc-crm.org/crminf/ that Phil Carlisle mentions) that will be included in version 4 of Arches.
The basic summary is that the drm-inf extension will let you create a branch that says "Actor X assigns a value of "Iron Age" to the cultural period with a certainty of 80%". The certainty value can be numeric as in the example, or a concept (such as "likely", "very likely", or "uncertain"). To support this, Arches version 4 will support the ability to reference another resource instance in a node, as you rightly point out isn't currently possible. Hope this helps, Dennis On Wednesday, January 11, 2017 at 2:41:41 PM UTC-8, Vincent Meijer wrote: > > Hi all, > > > I am working on an idea I have to record all interpretations made > regarding a specific (heritage) resource. > > I would like to *relate the assignment* of e.g. a cultural period or the > use/type of an object (hide scraper, spear head, vase) or an object > category (defensive structures, tools, jewelry) *to an authority*. > > This authority can be an actor or a (to be created) academic reference, > both resource graph types, rather than values in a regular > dropdown/authority document. > > > I want this in particular because it is easier for my users to create a > new resource than it is to add values to dropdowns via RDM.
