What is the Web 2.0
Definition
The term has been coined and defined by O'Reilly for designating the use
of technologies that improve the design of Web site, allows for collaborative
work, create a social networking. New tools allow to concentrate on the content
that is managed automatically. Web application and Web service become a bigger
part of the industry.
Examples
New kinds of activities and enterprises are appearing: Skype, EBay, Orkut, Second Life, and so ones...
Technologies used by the Web 2.0
These technologies are often combinations of older technologies for new uses, that change completely the appearance and functions of websites, just as chemical is made of combinations of molecules into new materials.
Ajax
Ajax is comprised of JavaScript, CSS, DOM and the XMLHttpRequest object for an asynchronous interaction. Perhaps the main component of the Web 2.0 as it allows to build Web application having the behavior of desktop ones.
PHP and server-side languages
Server-side languages allows to turn web pages into online applications and
to use web services.
PHP is the most frequently used and the simplest for small applications. Java and .NET are alternatives.
Mashup
A mashup is a combination of APIs provided by a site or different sites
to build new services.
The most usual example is the combination of Google Maps API and the catalog
of real state agency to allow customers to visit virtually an apartment and
the surroundings. This is used also for restaurants, shops, gas stations and
other services. Programming a mashup requires only JavaScript. Alternatively
you can use Mapbuilder,
define some locations and generate the code. See at resource for a list of
mashups.
Collaborative technologies
Various standards have been defined to exchange data and to create social networks.
RSS
Syndication allows to promote the content of a website thanks to an XML file
that describe the content, and that may be inserted into a Web page or used
from a browser.
RSS is
used asol for building social networks.
The OPML format has been
created to exchange outlines across the web and is used for lists of RSS files.
For building the feed of your website, you can use a model, as the rss.xml
one stored at root off this site and change the data. Or you can use a generator.
See at the RSS article.
To display an RSS feed, a PHP
function is sufficient (there is just two lines to include in your page).
Semantic Web
The goal of this W3C project is the creation of documents extended with information
about the meaning of the document. The document is enhanced with meta-data
and relational information. This adds meaning to documents beyond the content
and this is an additional information that can be processed by the computer
and facilitate exchanging data.
This
is a combination of formats as XML of RDF.
An application of the Semantic Web is the FOAF standard.
FOAF
Friend Of A Friend.
This is a network of persons virtualized on the Web by documents the computer
can process.
FOAF is extensively described here.
Websites 2.0
CMS
Professional websites are all using content management systems for now. Articles may be entered online, with a simple e-mail sometimes and the system creates the page and allows to retrieve it. Additionally, the CMS allows visitors to comments to articles.
Blog
What is very innovative with blogs is that not only each person can now
be a writer or a journalist, but each person is also sure to have readers.
The success of the writing depends upon the quality of the pages, and the
utility of the infos provided.
Anonymous persons can become famous with a blog thanks to blogolls.
More about blogs, how to make one and how to make money with a blog in the
article: Blog and Blogosphere.
Wikis
A wiki is a web site that is contributed and filled by visitors. It can be
turned into complete encyclopedia dedicated to a subject or universal.
A wiki
requires only a primary content management system.
Collaborative magazines
On these websites, articles are written by visitors, or summaries are sent
by webmasters for articles on they own website, or sometimes they sent just
an RSS feed. These contributions are moderated by the magazine and often visitors
are allowed to click to vote for the article and promote it on the site.
Some examples of such sites are Slashdot and Diggs.
Social networking and sharing
Social networking has been largely developed in the article Blog and Blogosphere.
This is a development of blogs and a complement to exchanging of videos
or audio material. The site blogsmark.com for example allows users to designate
websites they like and promote them.
Conclusion
A modern website is no longer a sum of web pages but a combination of technologies instead. A webmaster must be a technician for an innovative site, and even if there are websites as xul.fr that furnish you tools and scripts, you need also for some new technology that will make your site unique... But how to provide this unique service to reach the top without any expense? If you have carefully read the article, you have the solution!
