In seeking themes centered on scholarly activities undertaken against research materials, a related set of themes that emerged for me might best be summarized as "Gather." The Minnesota study uses this term as one of its four Primitives for tools of analysis and ways of thinking. To me, "Gather" has the connotation of bringing together those research materials which were located via "Forage" or "Discover" activities and then passed through "Filter and Synthesize."
"Gather" in particular seems to indicate simply laying one's hands (human or electronic!) on materials in a way that permits ready use and reuse by the researcher; assembling bookmarks, filling one's Zotero storehouse, amassing a pile of photocopies or borrowed library materials, stacking up media recordings, and the like.
"Create" in this analysis is used in terms of creating a collection or an archive or a rendering of something which one has discovered, for subsequent scholarly use, either by the creator or by others who might benefit from such a resource. Taking "Create" too far here bleeds into Minnesota's "Create" primitive, so this meaning falls short of scholarly creation here.
"Capture" in this analysis mostly focuses on the mechanical process of making a digital representation, or an analog recording of an event or object, or gathering associated metadata for an object. One might think of image acquisition, recording, remote sensing, and the like. This has links to the "Archive" theme where digitization is mentioned.
Finally, "Transform" in this analysis relates to migrating materials from one format or medium to another, such as producing an OCR representation of a scanned text page. Transform and capture have an overlap, but in looking at the planning wiki, in some cases transform seemed the better term than capture.
In the end, all of these are facets of the process of assembling a (yet-to-be-organized) corpus of research materials for subsequent analysis and manipulation. (The organization of this corpus is a separate but related theme to consider.)
