I was using SRFIs as a particular example.  In general, the layout I
propose would be
"repository/lib/library-name-part1/.../library-name-partN.sld".  Only
library definitions must reside under the "lib/" path.

> I’m interested in specifying a general layout that works for any library, i.e. (import (A B C)).  Also I’m interested in a layout for “publishing” libraries so that they can be accessed by a “library installer” (a vague term that means some procedure for using a library in a Scheme system… possibly a simple “cp -R X Y” for some Scheme systems and a “awesome-scheme-install X” for other systems).  So the layout is not prescribing how compatible Scheme systems store the libraries on the filesystem (that’s the Scheme implementation’s business).

The second allows grouping files related to library (A B C) in the directory A/B/C, for example included files like A/B/C/C-impl.scm, implementation specific files like A/B/C/C.chibi.scm, configuration files needed by the library, sublibraries, etc.

In the case of the second option, "A/B/C/C.sld", would a file
"A/B/C.sld" be ignored?

The location where a library comes from should be decided by the programmer using the library, not a self-selected group of people running a central repository (regardless of how good their intentions are).  In these days of the web revolution it should be clear that decentralization is the way to go.  But for this to work there’s a need for a standard publishing layout like the one I propose.

Agreed.  I don't propose this sister project to SRFIs as the only
place or process for publishing libraries.  It is intended to be just
one of the many decentralized places.  But it is intended to be a
well-known one with an active community and with some rules (based on
the experience with SRFIs) to have a certain level of quality, also
when it comes to documentation.

Then there’s a need for a policy for name registration when there are conflicting names or people who “park” names… I’d love to get the “mf” name for “Marc Feeley” to be able to do (import (from mf …)) but I’m pretty sure Matthew Flatt and Matthias Felleisen would like it for them too.

So what I propose instead is that this name be used to identify the author or organization, and instead of (import (from github.com/<account> …)) I propose the shorter (import (github.com/<account> …)) which should be unambiguous given that the use of “/” is valid but “inadvisable” in R7RS.

The advantage of this would be that the SRFI-sister organization would
only have to maintain a short registry, namely that of valid prefixes.
This list would contain "github.com/' or "gitlab.com". Or every name
with a "/" in it (for web addresses) and a "@" (for email addresses)
would be reserved.

Alternatively, one can think of what a non-normative appendix of R6RS
proposes, namely a Java-style naming: (import (org gambitscheme
compiler)). Or (import (com github mnieper)).

I am not so convinced that the library name and the repository address
are or should be in one-to-one correspondence.  It is a *package* (not
formally defined (yet?)) that is stored in a repository.  A package
can consist of more than one library.

I would leave the question how to resolve a package location from a
library name to the awesome-scheme-install program, which can use some
configuration file.
