Humanities scholars are loners writing monographs; funding agencies, however, like collaborative interdisciplinary projects. Resource production in the humanities is labour intensive, and reuse is desired (though not practiced).
Example attempt: collaborative wiki for the Early Mediaeval History Network. This was imposed onto an existing research community. Takeup was only after training, demo, and leading by example. And then --- it died again. So was it a success?
Shared resource library, semantic web underpinnings, on PLONE. "We built it, why aren't they coming?" (But there's no images in the library, no metadata, and no updates!)
Setting up collaboration: "What, not on email? Not another portal?" No activity, because the collaborationware was bolted on to the group -- who had no time to spend on the project anyway.
So how to make the culture change? Mandate works when there is support, but evaporates when there is not. Build And They Will Come? No: Hope is Not a Plan. Those who have to use it will use it? But it is not clear that they will.
To get takeup of collaborative infrastructure, make it part of the researcher's daily workflow -- e.g. daily workdiary.
