									What is web2.0
   When the interview asked the question a bit ft, because the only
known problems to solve, no standing in another level to consider the
development of optimization. New technology can give us Their future
career planning what Is a lifetime to write programs Really quite a
loss. I think this is rooted in my perfunctory inertia. No, no, IT can
not muddle along this line, I forge ahead and look under the bar.
   See a good post on web2.0, extract the. Want to learn something
from.




   What is web2.0 More than most people can not understand, many IT
professionals, said the unclear. I use a simple way to tell you about
what is Web1.0 and Web2.0, if you still do not understand the
difference between them, like him to criticism.

   With the wealth of human material, representing the high-tech, new
entertainment lifestyle brand new industry: monkey, appears in the
human face! Joe Smith, Sally, is a group of five other army in the
normal monkey, but a few outstanding.
   At first, Joe Smith rented a venue, get a few monkeys learned a
dozen jaws, they begin to show. Each audience received a dollar an
hour. But, after all, at the primary stage of socialism, the human
consumption level is not very high, to see a high-end entertainment
consumption jaws. Connotes a way that monkey, the daily audience of
about 100 also, Mr Tan very hard every day, the income is not high.
This is a newspaper.
   At this time, Sally also came a monkey. Zhang San Li Si fully
absorbed the lessons of successful experiences and failures, to take
another kind of philosophy, of course, may be just beginning to make
known to open the market. See John Doe monkey is completely free of
charge. In this way, each day, Mr Tan monkey only 100 people, and to
see John Doe on the monkey may have thousands of people. This time, to
find a seller stick John Doe, to John Doe 100, wherever he goes in the
corner put a John Doe signs saying: "Monkey King brand sticks, it is
the home tour, rob and kill the best choice"; after Lee Four publicity
wherever he goes, stick to business is good. So selling toys, selling
knives, and a fruit and so on wherever he goes at every corner of John
Doe placed signs, so John Doe sponsorship by the hundred every day to
earn 4,5. This is web1.0.
   Since the market lot of Joe Smith, John Doe, and fierce
competition, so more and more monkey business is not good to do. At
this time the king also wants to engage in monkey business, five, in
order to open the market to make known, Wang V provides a new
approach: to provide small monkeys playing to the spectators.
Spectators just before watching Hey, Sally De monkey show, spectators
can now own a monkey, playing the good, you can go wherever he goes,
the king is about five; playing in general can also be present to
their friends and family to see look. As for how to use this monkey
way to make money, the king has not completely like a good five. This
is web2.0.




To understand WEB2.0, come look at the history of WEB. World Wide Web,
referred to as the WWW, is a British TimBerners-Lee 1989 in the
European Community, serving a large research institutions were
invented. Through the WEB, Internet resources, a web page can be
expressed in more intuitive; and resources, between the pages can
chain to chain to. WEB1.0 made tremendous contributions to the company
have Netscape, Yahoo and Google. Netscape developed the first
large-scale commercial browser, Yahoo Jerry Yang made the Internet
Yellow Pages, and Google come from behind, launched a popular search
service.
Search the largest contribution is the amount of information on the
Internet Shanghai, with an initial sub-machine had a clue. However, in
the light know what keyword pages only address the needs of people
browsing the web. Therefore, Tim-Berners-Lee proposed WWW in the near,
began respected Semantic Web (Semantic Web) concept. Why Because the
content on the Internet, the machine can not understand. His ideal is,
web-production and structure of the database, we are in a semantic
way, the contents of the page representation into a machine
understandable format. In this way, the Internet has become a
well-structured knowledge base. From Ideally, this is very tempting,
because scientists and machines like things orderly. Berners-Lee is
concerned that the Internet data, and other Internet applications can
be repeated by reference. Give an example of the charm of a standard
database. Have a product called LiberyLink. After it is installed, go
here to Amazon, it will automatically tell you that a book can find
the local library user, serial number is how much. Because a single
book ISBN and title, two different Internet service (Amazon and the
local library database search) to the public to enjoy the data, to
provide new services.

However, after having introduced the Semantic Web, highbrow, not many
people respond. Why The hope of making web pages to provide so much
additional information to enable the machine to understand a web page,
too difficult; simply human to machine work. This violation of the
people to lazy to lazy nature. Look at the success of Google to find
out. Google has a Page Rank technology, the relationship between pages
link to each other, to do a sort based on the results, disguised use
of the web producers discretion. Think about those who made the page,
from the number, the ratio of the number of visitors is much less
pure. But Google on this one innovation, and use the website as part
of power producers, has been pushing him into the top of the Internet.

So the Internet the next step is to give everyone busy, weaving the
whole people, and then use the software, the power of the machine to
make the information easier to find and visit people in need. If
WEB1.0 core network is based on the data, then I think the starting
point of human-WEB2.0 Internet. We take a look at some recent WEB2.0
products, they can understand these views.

Blog: User weaving, publish new knowledge, and other user content
link, and then a very natural organization of the content.
RSS: automatic distribution of user-generated content, will be read

Podcasting: personal video / audio of the publish / subscribe

SNS: blog links between people

WIKI: Encyclopedia of the user to build a

From the perspective of knowledge production, WEB1.0 task is not
previously on the web of human knowledge, through the power of
business, on the web to go. WEB2.0 mission is to bring these
knowledge, each user's browsing through the power of knowledge,
collaborative work, knowledge of organic and organized, and in the
process to continue to deepen the knowledge and generate new ideas
spark;

From the perspective of content producers, WEB1.0 is a commercial
company as the main body to move the content to the Internet, and
WEB2.0 is based on user-based, simple and free way to through the blog
/ podcasting content to the new online way to move;

From the interactive view, WEB1.0 is the site based on user; WEB2.0 is
P2P based.

From a technical point of view, WEB client and the job increasingly
efficient. Such as the Ajax technology, Google-MAP/Gmail which used
superb.

We see the role of the user on the Internet more and more; they
contribute content, communication content, but also provides a link
between the content of these relations and browse path. Inside the
SNS, the content is user-centric to the organization. WEB2.0 is a
user-centric Internet.

So, in this sense WEB2.0, and Tim Berners-Lee Semantic Web, what is
different The starting point of the Semantic Web is structured and
repeatable data by machines called, made use of semantic content
publishing tools, trying to rules and technical standards to make the
Internet more orderly. Google and other search engines, Semantic Web
in no cases, as much as possible to provide a clue to the Internet.
WEB2.0 is encouraging users to use the most convenient way to publish
content (blog / podcasting), but by voluntary user (blog) or
automatically by human-centered (SNS) of cross links to these
seemingly messy content index. Because these leads the user to provide
their own, more consistent user experience. Gradually from the
Internet as the core keyword organization and reading, to the Internet
user's personal portal (SNS) as a clue, or personal ideological
context (blog / rss) way of reading the clue. WEB2.0 stressed that
collaboration between users. WIKI is a typical example. From this
perspective, the Internet is becoming more orderly, the contribution
of each user: either contribute content, or content of the order of
contribution.

View of the next generation Internet, there will be a lot of
discussion. To be sure, WEB2.0 human-core trail network. Provide a
more user-woven network of tools, encourage the provision of content.
Based on user traces on the Internet, organizations view clues, and
provide related services to the user to create new value to the entire
Internet to produce new values, is the business of the Road WEB2.0.




What is Web2.0



Web2.0 is Flickr, 43Things.com sites such as the representative to
Blog, TAG, SNS, RSS, wiki and other social software applications as
the core, based on Six Degrees of Separation, xml, ajax and other new
theories and new Internet technology generation model. "

Blog - blog / blog: Blog of the full name should be the Web log, later
abbreviated to Blog. Blog is an easy to use website, where you can
quickly publish ideas, communicate with others and engage in other
activities. All of this is free.

RSS - Site Summary: RSS is a site and other sites to share content
between a simple way (also known as polymer content) of the
technology. Originally from the browser, "News Channel" technology, is
now often used for news and other sites in sequence, such as Blog.

WIKI - Encyclopedia: Wiki - a collaborative writing tool for people.
Wiki sites can have many (or even any visitor) maintenance, everyone
can express their views, or to extend or common themes discussed.

Wiki refers to a hypertext system. The hypertext system to support
collaborative writing for the community, but also includes a set of
auxiliary tools to support this writing.

Web Abstract: "Network Summary", also known as "bookmarks", originated
in a Web site called Del.icio.us United States since 2003 to provide a
called "social bookmarking" (Social Bookmarks) network services, users
are called "Delicious Bookmarks" (Delicious in English means
"delicious; interesting").

SNS - Social Networking: Social Network Sofwaret, social networking
software, according to six degrees of theories, in order to understand
the basis of friends of friends, expand their contacts.

P2P - Peer Networking: P2P is a peer-to-peer abbreviation, peer in the
English language, there are "(status, ability, etc.) the same person,"
"colleagues" and "partners" and so meaningful. As a result, P2P will
be understood as "partner of the partnership," "point" means, or as
peer networking. There is now that the Master in strengthening the
network of communication, file exchange, distributed computing and so
promising.

IM - Instant Messaging: IM (Instant Messenger, referred to as IM)
software can be said is the highest rate of Internet users in the
software. Internet users are online chat has been one of the main
activities, online chat has been from the beginning of the main tools
for chat rooms, forums into the MSN, QQ instant messaging software as
the representative.

RSS is Really Simple Syndication (really simple syndication) acronym,
is a site and other sites to share content between a simple way, also
known as polymer content. Internet users can support the client by
means of RSS news aggregator tools (such as SharpReader NewzCrawler,
FeedDemon RSSReader), website content page without opening the case of
reading out the website to support RSS content. Can be seen, the
website provides RSS output, is conducive to allow users to find Web
content updates. High quality and efficiency at high speed into the
mainstream voice of the Internet era, RSS undoubtedly contributed to
the online dissemination of information, proposed an alternative way
of looking at the world.

RSS, Web content, such as intention that the title, link, part of the
text is converted to text or Extensible Markup Language (XML:
eXtensible Markup Language) format to feed to other sites, users can
use normal browser viewing, but also can use special "reader" software
to read.
History is important. A technical study of history should proceed at
the time of its formation by the flow of history, be aware of status
quo, or even be able to predict the future.

That Web1.0 is it

They say, remember the era of static HTML of the WWW it

(WWW application of that era, people's Web experience, the social
impact )

Dynamic HTML, and then under a static HTML Web compared to how many
versions 1.5 Yes, they are really called it.
(On the effectiveness and impact, compared with 1.0 to expand and
deepen how much )

The data to be rendered is stored in the database, Web service through
the end of the program, should the user's request, remove the data,
combined with pre-designed templates, Html code dynamically generated,
sent to the user's browser there.

He is the 1.0 series, users should be seen in the browser and Web1.0
as it has 0.5 upgrade, because the data is not produced and
distributed in advance, but dynamically generated, and users need to
interact generation.

Well, plus 0.5 to Web2.0, change is in the wrong

(See the rising and changing, and will continue to change in the
direction toward the Internet and society )

Update: On the difference between each version, see the Amazon
example.

Things are not so lucky, Web2.0 is not a concrete thing, but a stage,
this stage is to achieve a variety of technology and related products
and services of a call. Therefore, we can not say, Web2.0 is, but it
can be said, that is Web2.0.

WikiPedia Web2.0 entries listed under these conditions:

* CSS and XHTML markup semantically related

* AJAX technology

* SyndicationofdatainRSS / ATOM

* AggregationofRSS / ATOMdata
* Simple and meaningful URLs

* Support for publishing the weblog

* RESTian (preferred) or XMLWebserviceAPIs

* Some elements of social networking

Must have the elements are:

* Web site should be able to allow users to shift the data within and
outside the site.

* Users on the site have their own data within the system

* Based entirely on the Web, all features can be done through the
browser.

(The above is quoted from the English Wikipedia)

Although this is only one of the words, however, for several elements
of which it comes, we still recognized.

- Based on RSS / ATOM / RDF / FOAF, etc. XML data synchronization,
aggregation and migration.

Data pages and Web sites are no longer mixed and glued together, it is
independent, it follows the user to go. This is a very important
feature of Web2.0. This is why representatives of Web2.0 Blog is the
reason. In the blog, the protagonist is often independent of each
other is a blog.

Independent, then there are the physical performance. Now, you can
make them active again. Through XML data processing, the combination
of these elements can be free, is a variety of applications, whether
Web or desktop applications to present a program and process.
Of course, the most important thing is the people behind.

- Social factors.

Content is following, the content and can be a combination of user
freedom, that is, the contents of the user with the freedom of the
media can create one from the community, the occurrence of various
social in nature (network) behavior.

There are also labels and label systems built on the open top of
Folksonomy.

- The third factor is the recognized open API,

Slightly stronger than the more technical, may also take the time to
study, you can look at an example: amazon, flickr, googlemap and so
on.

Web applications from the product / service producers point of view,
how to create Web2.0 products

It is important to grasp such points, one is a micro content (defined
here), one is the individual users. In addition to these two basic,
you can also consider sharing within the community and provide API.
