I already operate a gateway at http://oai.repec.openlib.org.

Correct, and almost all are economics faculty.

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. > What distinguished Repec is hence not its interoperability protocol > (since it plans to become OAI-compliant anyway) but (a) its activism > and (b) its discipline-specificity. and (c) its metadata model.

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.) > http://www.earlham.edu/~peters/fos/timeline.htm It is for this > reason that it is OAI-compliant institutional self-archiving that I > happen to be promoting.

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. > At first, FTP sites and Web sites seemed the simplest, fastest and > most direct way for researchers to self-archive, on a distributed, > institutional basis; 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. > but then the slow progress in this, and the success of the > physicists' centralized disciplinary model suggested that > centralized, discipline-based self-archiving might be faster, with > the Physics Arxiv itself perhaps subsuming it all > http://cogprints.soton.ac.uk/documents/disk0/00/00/16/99/ (Thomas > Krichel argued against central archiving, 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. > But central archiving did not catch on (Cogprints has only reached > 1500 papers in 2003) or generalize to other disciplines, 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. > and Arxiv itself kept growing at only an unchanged linear rate from > year to year: http://arxiv.org/show_monthly_submissions Sure, but it is still is the finest self-archiving project on the planet.

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.
