Neighbor to Neighbor was one of those primarily photo.net packages
that was never ported from ACS 3.x to 4.x, but it definitely shipped
with both
OpenACS 3.2.5 and
ACS 3.4.10.
I think the version shipped with OpenACS 3.2.5 is the latest for
PostgreSQL.
ACS 3.4.10 was not the end of the ACS 3.x line (there was ACES, I
think also ACS 3.5, etc.), but I suspect Neighbor to Neighbor was not
changed in any of those last few ACS releases. So my guess is that
the 3.4.10 version was probably the latest release for Oracle,
although the photo.net folks may have made further un-released changes
to their version.
I'm not really clear on exactly what Neighbor to Neighbor did, to what
extent some of its functionality might be present in other more
current OpenACS packages, nor how to would be best to re-create it for
a modern OpenACS 4.x/5.0 system. Maybe someone else here can chime
in...
Failing that, for more info on Neighbor to Neighbor, you could ask
Philip
or one of the other photo.net folks.
The comments in the www/doc/sql/neighbor.sql
data model
imply that it was considered very old and crufty at least as far back
as early 2000, but it's quite a small system, only 3 or 4 tables, so
figuring out how it worked and possibly porting it shouldn't be too
hard.
