A content management system is a computer software system for
organizing and facilitating collaborative creation of documents and
other content. A content management system is sometimes a web
application used for managing websites and web content, though in many
cases, content management systems require special client software for
editing and constructing articles. You can add/edit content, display
it in various formats (for example html vs. pdf vs. rss) and usually
manage the content of a website with a cms. Some definitions, or
better, some of the feature lists of more popular cms' go way beyond
management of content, getting into actual site building, adding of
modules like polls, newsletter sign-ups etc. cms does not mean site creation but site content management.
To
fully understand what it is a CMS does, we have to first define a) what
it is we are referring to when we talk about content b) what it is we
understand under its management and c) what do we mean by a system. Content
is in essence, any type or 'unit' of digital information. It can be
text, images, graphics, video, sound, documents, records etc - or in
other words - anything that is likely to be managed in an electronic
format. Content Management is effectively the management of the
content described above, by combining rules, process and/or workflows
in such a way that its electronic storage is deemed to be 'managed'
rather than 'un-managed'.
The system itself is definable as a tool
or combination or tools that facilitate the efficient and effective
production of the desired 'output' using the managed content.
"A CMS
is a tool that enables a variety of (centralised) technical and
(de-centralised) non technical staff to create, edit, manage and
finally publish (in a number of formats) a variety of content (such as
text, graphics, video, documents etc), whilst being constrained by a
centralised set of rules, process and workflows that ensure coherent,
validated electronic content."
MODX CMS = OPEN SOURCE PHP APPLICATION FRAMEWORK.
MODx is an open source PHP Application Framework that helps you take control of your online content. It empowers its users to build engaging "Web 2.0" sites today, with its pre-integrated Scriptaculous and Prototype libraries. Not only does MODx help you build sites quickly, but it also is both robust and simple.
Who uses MODx? Bloggers, developers and other members of the digerati looking for more, MODx can help take it to the next level. MODx makes working with the tools du jour easy, be it Ajax or the most highly search optimized CSS/XHTML sites. MODx allows you to focus on usability, design, content and building great sites, not on the tools that build them.
The SEO CMS: MODx helps you build sites that perform well in search engines – in fact, we think it's a great SEO CMS. Typically,
sites with minimal code/markup compared to the actual words on the page
fare better in the search game. Aguments with lots of good evidence
behind them abound for that lean, semantic XHTML/CSS sites gives the
words more weight or "relevancy" (a very important SEO term) compared
to sites that are built on top of bloated structures with loads of
non-semantic markup (typically, table-based sites). MODx makes
creating sites that search engines can love almost automatic. What you
put in it and however you want it to look is what you get out of MODx. Write XHTML code that puts the important content as close as possible to the body tag
We
don't force a cumbersome template language or "block" or "3-column" or
"channel" or "insert-favorite-term-here" template system. In fact,
creating a template in MODx is as simple as taking some static XHTML
(or HTML chock full of tables even!) and replacing a few key areas with
things like [*pagetitle*], [*longtitle*], [*description*], [*content*],
[*sidebar*], [[Menu]] and {{footer}}. That means you can build a
super-clean XHMTL/CSS driven site that uses the minimum amount of code
so search engines have nothing but your content to think about. Every MODx page has several bits of "metadata" that are automatically available to every page. The
way your browser's URLs return are also important in the Search game.
Google arbitrarily refuses to index URLs containing "?id=". Many argue
about how URLs should be written, so that's why MODx and mod_rewrite
let you do it whichever way you prefer. You can create URLs manually or
dynamically in several formats:
* http://mysite.com/p1234.html (or .cgi or .jsp or .aspx or .php or .cfm or .anythingyouwant) * http://mysite.com/1234 (no extension) * http://mysite.com/page-name.html (manually created) * http://mysite.com/page_name.html (automatically created from the page title) * http://mysite.com/some/subfolder/pagename.html (uses site hierarchy and allows for duplicate aliases in different pages) * any combination of the above
Meta Content Management (including Keywords)
The MODx Ajax CMS and PHP Application Framework brings plenty to the table, with more on the way, including:
*
Strong Web Standards Support – MODx does not force you into awkward and
confusing blocks-this or channels-that templating engines or layout
rules. You can build XHTML 1.1 Strict sites just as easily as a
tag-soup laden table layout. MODx is the dream CMS for CSS designers. *
Web 2.0 Features (yes, that means Ajax) – MODx is the first free PHP
CMS to offer an API that fully supports Web 2.0 Ajax technology thanks
to script.aculo.us. Expect to see this grow more and more into our
manager over time, but you can make use of it today in your own custom
applications including live search, web effects, Ajax communications
and more. * PHP Application Framework – a flexible API and a event
model that allows to override how the core behaves means that you get
both tremendous flexibility, but also the ability to customize the
solution to your needs and a simple upgrade path. * Works in your
favorite browser – and yes that means Safari! You can manage your
websites from anywhere in the world with an internet connection and IE
5.5+, Safari 1.3+, Firefox 1.0+. * Graphical Installer – it's now
easier for less experienced users to get up and running fast with a
step-by-stop online installer. * Improved Rich Text Editors – All
MODx RTEs are optional plug-ins, making for a smaller base download.
FCKeditor ships out of the box. Adding new RTEs to MODx is simple with
TinyMCE available now as an optional download and Textile, Markdown and
widgEditors on their way. * Better handling of aliases and menu
indexes – Search Engine Friendly aliases are automatically created from
the page titles and the system will check for alias conflicts before
saving a page. Reordering your pages with Ajax-enabled drag and drop
indexing. * Robust CSS Menu Builder – Menus made from ULs are ready
to go out of the box. Whether you want something simple as a bulleted
list for a sidebar or as complex as Big John's deluxe menus complete
with CSS "hover zones", MODx has you covered. * Improved Meta-tag
and keywords controls – consider MODx your #1 free Search Engine
Optimization CMS. MODx helps your SEO efforts by making it easier to
adjust meta-content of your site on a per-page basis. * Separate Manager and Web User sessions – simplify your testing and development workflow. *
Improved Document Parser and Error handling – build better custom
applications with a more robust API and greatly improved error handling
and reporting inside the manager. * Custom Content Types – use MODx
documents to manage your linked Style Sheets, Images and Javascript.
Transform them into XML, PDF, Excel or Word documents with snippets and
this handy new feature. * Bug fixes and usability tweaks – a more
polished and robust product, bringing us to the home stretch to the
official project launch and 1.0 release.
Finally, MODx also
provides several ways to manage the meta content on every page. You can
use {{chunks]] to create sets of meta content, or it's built-in (but
optional) meta content management system. As an editor there are two ways to publish content:
* in the main Content Area, and * in other areas called Template Variables (traditionally side blocks, but they can be placed anywhere on the webpage).
There are two important feature of MODx that you you need know about:
*
Chunks - these are re-usable pieces of HTML content. You can place a
Chunk in the main content area or in a template variable. For example,
you could put your contact details into a Chunk and then you can
publish them in different places on the your website without re-typing
the details. * Snippets - these are small functional items, such as
menus and search bars. These can be published in the template, a
document's main content area, a chunk or in a template variable.
A
Chunk or Snippet can be placed directly into the template by your web
developer, or inserted by you into the Content Area or a Template
Variable.
* The template contains the main framework of the
webpage. Your web developer may choose to have content that appears on
every page in the site. In this example the header and logo are fixed
in the template. * The template contains the Content Area,
identified in pink, and inserted into the template with the syntax
[*content*]. This content is taken from the Document as edited in the
Manager. * The template also contains MODx tags that insert
Snippets. In this example there are two menu Snippets, identified in
blue and inserted with the following syntax [[SnippetName]] * The
template contains Template Variables that allow the Editor to insert
text, images and other content items outside of the main Content Area.
These are identified in green and are inserted in the template with the
following syntax [*TemplateVariableName*] * The Editor can insert
pre-set pieces of text or html into the Content Area or a Template
Variable by using Chunks. In this example there are two Chunks
identified in red. Chunks are inserted by the editor by typing into the
Content Area or a Template Variable space.
