  The interoperability is more complicated then in a conventional
  OAI setting, because the structure of the data exchanged goes will
  beyond what can be done with oai_dc.

  I already operate a gateway at http://oai.repec.openlib.org. It's
  oai_dc data may be a bit thin, but there is plenty of AMF metadata.

  Departmental archives, as distinguished from institutional archives.
  Some archives serve special purposes, they hold no docuemnt
  data at all.

  Correct, which is basically just a way to dump files on a disk,
  nothing more.

  Correct, and almost all are economics faculty. Some folks do 
  little, but the construction of the whole enterprise means that
  even if they do little, since there are many

  The technical protocol for the transport matters little. This
  really (!) is a technical matter. We continue with what we
  got because we can not rearrange 250+ archives that otherwise
  do just fine.

  and (c) its metadata model. This is by far the most important, but least
  well understood distinction.

  Could not agree more.

  RePEc has its origin in a project called WoPEc that I started on
  February 1, 1993. In 1997, RePEc was born essentially out of WoPEc
  and some other partners, but WoPEc had the lion's share (I am
  simplifying here a bit.)

  There is no contradicition between institutional and departmental 
  archives, and aggregator strutures. It is by no means an either
  or choice. And let me emphasise again: having discipline-based
  aggregators will be the best way to stimulate institutional 
  and departmental archiving. The problem is, of course, that
  there are not many aggregators around. Therefore I have been
  argueing for a while thet the institutional self-archiving
  community should stick together to elect one area of discplinary
  priority. That is rather that to fight a war on all fronts,
  concentrate the effort and build systems that are interoperable
  beyond the unqualified DC data model. The DC data model is too simple
  for academic self-documentation.

  They still are, just look at the amount of stuff that is on the
  web. There are so many grass-roots initiatives. The larger
  public is not aware of them because they serve specific communities. 
  This is where I get so angry with Clifford and his---implicit---call
  to shut them down, to fit all publishing activities into a central
  straightjacket.

  Nope. I simply argued that the centralized model would not
  carry through to many disciplines. Where it worked it 
  was certainly an extremely good model. But you insisted
  that because the Physcists had done it everyone could
  and would, it was the optimal way (your flavour of the day).
  But I am still right. arXiv has a very unequal distribution
  of papers even in sub-areas of Physics, I am told. Ebs will
  know better. arXiv is still growing and that is a good thing.

  Exactly as I had forecasted! And that, depite the fact that
  it was a project subsidized by public funds. When WoPEc became
  a funded project, by the same funders, it had around 5,000
  papers accumulated as a labor of love, only. Much of that
  work was done by José Manuel Barrueco Cruz.

  Sure, but it is still is the finest self-archiving project on the planet.
  But it really is self-archiving. Self-archiving is only a part 
  of what I call self-documentation.

  They are not quite, but that is a matter for another email...

  And I think your team are doing a very good job with this.

  Citeseer are a truely fab project. The material that is there
  should become part of new, RePEc-like data structure called
  rclis and pronounced "reckless". Watch out for it over the
  next few years.
