Re: [school-discuss] Metadot and MIT
I definitely agree with you regarding to the database abstraction
layer!! One of the problems in open source is the string of intricate
decisions one must make in order to decide on the selection of
application layer programs. At the hardware level, if you have a
variety or hodgepodge of equipment from a variety of manufacturers,
installation of an operating system is more difficult. In schools we
see both older Macs that can't run OS-X and older PC's that can"t run
XP, and keeping track of the various licenses related to these machines
over time is arduous. This is one component in our ROI/TCO equation.
This is why we have chosen for our push into schools a special fork of
the Gentoo Linux. It is harder to initially install, but then
everything gets a lot easier after our initial reference CD-ROM is burnt
and then either updated via Portage or via a reference CD-ROM for
isolated machines. For instance in a network of 100 rich clients, one
server can update all sites in a matter of minutes. In addition, not
only is Gentoo a strong, mature nonprofit offering with a great support
structure, Gentoo is also multiple platform, thus runs optimally on
PPC's, INtel, AMD, AMD64, etc. Going up the layers now is determined
via a very explicit set of goals and objectives, where software is
loaded in a minimalist fashion based on its perceived use and need at
the server or workstation level, rather than the Redhat/Mandrake kitchen
sink approach. Ease of installation in a school environment (the forte
of the debian based Xandros) is not a major issue, since there is
usually a group of parents, or a paid SysAdmin, or as in our case, we
install the reference distributions as part of our site-based to do this
step. Ease of maintenance and ease of upgrade is more important.
Selecting applications under Gentoo is a whiz -- just say "emerge
opengroupware" and it gets done!!

I will check out ez publisher.
I run mysql on several servers without violating the GPL. MySql is
dual licensed, GPL and their commercial license, similar to the ez
publisher dual GPL and commercial license.
Not being able to use multiple databases detracts from a products
usefulness for me. If it is written using a database abstraction
layer, like the perl DBI/DBD or php's Pear DB or adodb the product can
easily use multiple database back ends. I once saw an internal
product moved from mysql on HPUX to mssql on Windows NT with changes
to a couple of connect strings thanks to the DBI/DBD.
It's good to hear the mysql developers sought assistance from the
postgres folks, and I am sure the postgres folks were more than
willing to help. That tells me FLOSS developers are trying to create
the best products possible.

ez publisher! With regard to mysql, to distribute it within your
organization, such as on several servers, requires a commercial
license. Postgresql is Apache licensing. Many CMS or CRM packages
can now use postgresql but not mysql. There are several comparison
studies on the web which document the differences. In fact, at the
last Linuxwolrd, mysql sought the assistance of postgresql in
improving. Mysql is better at marketing. My comparison was taken

Haven't tried Metadot, mainly because I think mod_perl is a pain.
The project does appear to have lots of small and large users,
middle school through large U's.
MySql is GPL licensed and freely available for download and use. I
find MySql every bit as good as Postgres for most uses, and a lot
easier to set up and maintain than Postgres or Oracle.
A lot of the features you cite as not being available in Metadot
apparently are, listed both at the cmsmatrix site and the Metadot
feature page. What is your suggestion for a CMS/portal doing all of
the things you state Metadot lacks?
Michael Dean wrote:
if one wants to compare CMS/portals go to cmsmatrix.org. I have
some problems with metadot, which I have looked at in detail for
smaller schools. First, it is written in perl, which when it
scales is very slow. Second, you need mysql or oracle to run it.
Fine for big universities, who usually have Oracle, but if you want
an open source solution in your middleware as well as user
applications not so fine. Mysql also costs money, and is not a
comparable (not as good) database to either Oracle or postgresql.
second, it does not provide an audit trail, no content approval,
requires use of LDAP for authentication, admin is not notified of
problems, does not run under SSL, has no commercial certification
or documentation, no online help, does not provide a structure for
third party developer add-ins, no drag and drop content, no undo,
no advanced caching, no database replication, no content staging,
no affiliate tracking, no deployment as a package, no way to trash
old content, no web statistics, no web based translation
management, no workflow engine, no ftp support (even scp), is not
WAI compliant, no webdav support, not xhtml compliant, no cgi
support, no interface localization, not metadata support, is not
multi-lingual, or wiki aware. no chat, no classifieds. No contact
management, no data entry, no database reports, no groupware, no
guest book, no bug reporting/help desk, no HTTP proxy, no surveys,
no tests/quizzes. The keyword here is NO!
One of schoolforge's affiliates was totally trashed last weekend by
a porn marketeer who placed 2500 links to porn sites in the
comments section of every artricle about school software. This is
why content approval and moderation is so important in your
software, especially in grade schools. Also, one would want to
audit who does what on your site, because trashing your site with
porn in the US is a felony.

Just to announce that Metadot Portal Server software has a new
university user: MIT.
Metadot is used by numerous schools and university including
Berkeley, Pace and many orders for their intranet, extranet or
organization websites. Metadot provides content management,
collaboration and portal (like My Yahoo) functionality. The key
differentiator is the extreme ease of use so that non technical
users can manage the content without asking their busy IT person
