Some months ago Henk Ellermann wrote about a Dutch study on the extension
of the OAI-PMH:

    OAI and OA-X: Yet Another Introduction,

The project was about carrying the full-text and automatic
uploading. I would like to know if they are still working at it.
Similarly, we could think of other extensions of the protocol, fo
rinstance to carry information about the presence of a full-text
paper (without carrying it!), or about any refereed-unrefereed,
published/unpublished tag. An extension of the protocol has already be
proposed for conveying information about rights, cfr. beta specification: All this will
be useful to extend services around OA literature - after the goal of 100%
OA has been reached ;-)

This is an example of how a paper in an EPrints archive (E-LIS, looks like in Google Scholar (search by "de robbio"):

Resources for Mathematics in the Scientific Virtual Reference Desk A De Robbio -

As for what is harvested and what is not, we have explicity asked Google to
do so for the repositories we manage. We got the answer that it is going to
be done soon. So it looks that in some cases a positive action is needed to
be included.

I would find an OA-only filtered Google Scholar unhelpful for
several reasons, all versions of the following one:

When I search the literature I *first* want to know about what
there is, and *after* that I worry about what I can get hold of.

In any event, trying to get Google to provide 'censored' results
is a side-show issue. If all the research was available by OA,
everything in the search results would be freely available.

Also, since accessibility improves citations, stuff that is OA should
look better on the Google results censored or not. (They start with
the most cited at the top.)

The intent is not to restrict access but to refine your search. It may be
compared to Google's advanced search option
( that allows you to specify
that search results return a specific file format, language, etc.

May I suggest that a clear label identifying what's OA, as Jan
suggested, would provide the metadata necessarily to filter, as David

This strikes me as one simple piece of metadata - a little tag that
says, "this item is open access". It shouldn't be difficult to do this

as a batch process with entire collections, such as institutional
repositories. When publishers make material OA after an embargo
period, as part of the the process they could turn on this little tag.

This could work not only for google scholar, but for many other search
engines as well.
