History of Content Management Systems

What's a Content Management System (CMS)?

Note: this document is now old and incomplete, and no longer fully describes the Bahá'í Library. See e.g. history of BLO.

Simply put, a CMS is a complete computer system that manages information. A
CMS can be programmed in any computer language and run on any computer system.
It allows data to be input, stored in a database, edited by authorized users,
and displayed to the public. A good CMS handles every aspect of formatting, storing,
cataloguing, and retrieving data, which means that editors and users don't need
any technical expertise and don't need to use a special program. CMSs are used
both professionally, by newspapers, libraries, online stores, academic journals,
and non-professionally, for personal applications like online photo albums, diaries,
and music collecting.

The best way to explain what a CMS does is to summarize the way it's being
used to upgrade the Bahá'í
Library Online [note: as of August 2003, when the system was under initial construction. -J.W.]. I'll describe the painstaking, slow old way and the fairly error-free, infinitely-expandable, multi-language
new way. Note that all the points in the old method start with "I", but the new
method is done by "Users" -- turning the Bahá'í Library into a CMS thus weans
it off of a single editor and opens it to the world.

The old way (a partial summary):

Documents are emailed to me in a variety of formats

I manually convert all the formatting to HTML

I use a number of professional, often complex programs to create content:
PhotoShop to edit images, RTFtoHTML to convert Word documents to HTML, DreamWeaver
to edit HTML, and numerous helper apps

I compile all document info I can find and create a blurb for index pages

I add links to the new site to the index pages, the "What's New" page, and
possibly 2-5 other cross-reference links

I add the document to my Microsoft Word-based list catalogue

Making corrections: I manually make any corrections in the HTML document,
test, and upload the new document

If anything more than cursory changes are made, I re-convert the entire document

I search for all links that need to be updated and change them one-by-one

My time commitment: 2 hours/day every day every month every year.

Pros: full control over formatting and cataloguing

Cons: only works well with sites of a few hundred files (the Bahá'í Library
now has 18,000 files); site ends up being full of errors, dead links, outdated
content, limited crossreferencing, and becomes wholly unmanageable for an individual
or even a small team of individuals.

The new way (a complete summary):

I program an interface in PHP and set up a back-end database

All further content is added by public users, not by myself

Users login, then are taken to an upload/editing screen, where they contribute
new content or update preexisting content.

When users click "update," the system (1) formats basic HTML automatically;
(2) prepares the blurb and as many index entries as are cross-referenced; (3)
catalogues the document; and (4) displays the document to the public

Making corrections: users login and make any updates they wish; the
system then stores and catalogues the corrections across the entire site

My time commitment: 1000 hours up front (300 initial programming, 200 upgrades and module additions, and 500 hours for manual data migration, copying all information for each file into the database in each appropriate field), less than 30 minutes/day from then on.

Pros: Anyone can register, upload content, correct errors, and add crossreferences;
site is easy to navigate and search; content is always up-to-date; site can and
soon will house millions of files; site can handle documents in any language

Cons: Limited flexibility; significant up-front time requirements

How's it work?

Easy to explain. First, understand that there are two computers involved in
any internet transaction: the home user's "client" computer, which sits
on her desk at home or office, and the website's "server" computer, which can
be anywhere in the world (and often is). The client-side computer is called the
"front end" and the server-side computer is called the "back end".

In the old way of doing things, a website editor has to run a bunch of programs
on her home computer in order to create a webpage. She has to use one program
to edit photos, another program to convert documents to html, another program
to upload them, yet another program (an internet browser) to view them online,
and a handful of other specialized programs for various webmastering tasks. This
requires installing a lot of expensive software on one's own computer, learning
how to use it, and keeping up with regular upgrades. Other than storing the files, the server computer does almost nothing
-- all the work is done on the client-side computer.

With a CMS, the only program a user has to use is the internet browser
like Internet Explorer or Netscape, and everything else is done on the
server. After preparing the HTML, an editor uses the browser to upload and edit documents and the server
software takes care of the rest. In other words, it's almost a complete reversal of the
old method! This puts all the burden on the website programmer, and relieves the
home user of any technical knowledge.

Here's the actual process:

User goes to the website, logs in, and goes to an upload page

User enters all text, with or without html formatting, into a form and clicks
"submit"

The form is sent to the server, where a back-end PHP script reads the data,
processes it as required, and saves the data in a back-end database called MySQL.

When a webpage is requested, the PHP script fetches the relevant data from
the MySQL database, adds any necessary html formatting, and generates a new html page on-the-fly.
This page is what appears in the user's browser. It looks like a normal, manually-created
html page, but is actually generated anew by the PHP code every time it is requested.
It is not static, but is dynamic.

Content Management Systems represent a wholly new paradigm for using computers.
Home users have taken two decades to get used to the idea of a file system, where
data is stored in discrete documents, each with a name and a location in a directory.
This paradigm was intended to be a close facsimile to a real office, with desktops,
files, folders, and so forth. In a physics analogy, this is a Newtonian virtual
world.

CMSs will lead users to accept a new paradigm, one in which the filesystem
has been discarded in favor of a database backend which is interpreted by PHP
and the HTML interface is created on-the-fly. In this paradigm data is nebulous
and without fixed form. In our physics analogy it is a quantum reality, where
content is only given shape in the process of interacting with it. It is thus
an extremely flexible virtual world, where structure is created by interpretation
and can thus be infinitely expanded, shaped, and delivered.

History of CMSs

CMSs as described above have existed for at least a decade, and were first created as custom-coded
internal computer networks for libraries, newspapers, and other information-oriented
sites. Now the term is used almost exclusively to refer to web-based systems.

1992-95: In the early days of the web, CMSs were employed only by big-budget
websites such as Amazon.com. They were programmed mostly in C++ and were run on commercial
databases like Oracle. Set-up costs ran into the millions of dollars.

1995: In 1995 the first free, or "Open-Source", CMS was created for
the Portland Pattern
Repository. The programmer named his system "Wiki Wiki," Hawaiian slang for
"quick and easy". He credited the seed for the system to Apple's Hypercard, which
was released in the mid-1980s and has been said to be the first true CMS.

1997: PHP, a dynamic HTML engine first created in 1995, was retooled
and was released to instant acclaim for its versatility, stability, and ease-of-use.
The acronym "PHP" originally stood for "Personal Home Page" but was rechristened
"PHP Hypertext Processor".

1995-1999: Thousands of Perl-based Wiki sites appeared around the internet,
each devoted to highly specific areas of interest and each with numerous dedicated
contributors. A number of PHP-based CMSs also appeared, such as PhpNuke and PostNuke,
and a combination of the two called PhpWiki (which is in use at bahai9.com).
However, they were largely of interest to techies only and not common. Most CMSs
of this period remained those created by well-funded companies and used proprietary
("expensive"!) software such as Allaire's ColdFusion, MicroSoft's ASP "Active
Server Pages," and Oracle databases.

During these years three other Open Source elements matured: the back-end database
program MySQL, the server operating system Linux, and the webserver software Apache
all became more useful and more stable, and enjoyed widespread implementation
by host providers, meaning they became available to home users at low cost.

2000: PHP 4.0 was released, which was a vast improvement on all earlier
versions. Now all the pieces were in place to witness the beginnings of an Internet
revolution, one which is just now becoming apparent. The combination of a free
stable operating system (Linux), a free web server (Apache), a free backend database
(MySQL), and a free easy-to-learn HTML generator (PHP) allowed web developers
to build and manage complex sites at little cost and without years of technical
training. These four tools together are such a complete and well-integrated package
that they earned the designation LAMP: Linux Apache MySQL PHP. (Not all
open-source CMSs use LAMP -- there are many variants on this combination, e.g.
using Unix instead of Linux or coding in Perl instead of PHP -- but the LAMP combination
is so common that it serves as a useful shorthand.)

2003: Fast forward three years to an internet landscape very different
from the 1990s: anyone can now do for free and on their own something equivalent
to the system Amazon.com invested millions of dollars and thousands of people
to create just a decade before. In the past three years the number of LAMP sites
blossomed from a few dozen thousand to millions. LAMP enthusiasts claim that the
advantages over the proprietary systems like Microsoft and Oracle are not only
price but also ease of use, stability, security, and large, helpful user communities.
Not only do proprietary systems often not seem worth their price, they can be
harder to use and less secure as well.

2005 [addendum]: Above I mentioned "an Internet revolution". This is a topic worthy
of another presentation, so for now let me offer an observation and a prediction.
My observation is that keen observers of contemporary social and political trends
are beginning to suspect that the unfolding of the information age has been accompanied
by an unprecedented transfer of political power from the American people to the
forces of technology and capital. However, the same computer technologies which
have allowed capital to control the emergent plutocracy may also provide the seeds
of its undoing. My prediction is that by the end of 2004 Americans will be very
familiar with the words weblog (or blog) and sites such as MeetUp,
IndyMedia, or
WikiPedia, and
will credit such CMS projects with helping revitalize and eventually restore democracy.
