Top Technology: Learning the steering wheel of Web 2.0
History is very important. Of a technical study should also be starting from the history, through their time in the history of the formation of rheological, to be aware of the status quo, or even to predict the future.
The Web 1.0?
They said that the recall of static HTML WWW times?
(WWW application of that era, the people's Web experience, the impact on the community?)
Dynamic HTML and then static HTML of the Web compared to what is available? 1.5? Right, they are really so called.
(In the effectiveness and impact, compared with 1.0, expanded and deepened?)
To show the data stored in the database, Web server through the procedure, the request should be user Remove the data, combined with the prior design templates, and dynamic generation Html code sent to the user's browser where.
He is 1.0 series, users should be seen in the browser and Web 1.0, 0.5 upgrade it, because data were not produced and released in advance, but dynamically generated, and the needs of users of interactive generation.
Well, in Canada 0.5 to Web 2.0, where it changes?
(See the emerging and changing and will continue to change in the direction of what the Internet and society?)
Update: on the difference between the various versions, look at the example of the Amazon.
Was not so lucky, the Web 2.0 is not a specific thing, but a stage, this stage is to achieve the various technologies and related products and services of a call. Therefore, we can not say, what is Web 2.0, but it can be said that these are Web 2.0.
Web 2.0 WikiPedia entry to the following conditions:
* CSS and semantic XHTML related markers
* AJAX Technology
* Syndication of data in RSS / ATOM
* Aggregation of RSS / ATOM data
* A concise and meaningful URLs
* Support for the release weblog
* RESTian (preferred) or XML Webservice APIs
* Some social network elements
Must have elements:
* Web site should be able to allow users to data in the system and beyond Daoteng website.
* Users in the system has its own web site data
* Based entirely on the Web, all through the browser function can be completed.
(English version of the above quote from Wikipedia)
Although this is only one of the statement, however, talked about several elements which we still recognized.
— Based on the RSS / ATOM / RDF / XML, such as FOAF data synchronization, polymerization and migration.
Data pages and Web sites no longer mix and stick together, it independent, with users taking it. This is a very important Web 2.0 features. This is why Web 2.0 is the Blog of the reasons. Blog, and often protagonist is independent of each other, one of the blogs.
Independent, and then a physical performance. Now, we can let them become active again. Through XML data processing, these elements can be a combination of free, by various applications, whether Web or desktop procedures, such as procedures for processing and display.
Of course, the most important thing is that the people behind.
— Social factors.
With the people of content, content also can be a combination of user freedom, that is, users can freely use the content of the media, create one from the community, in all kinds of social in nature (Internet) act.
In addition, label and the establishment of the open-label system on the Folksonomy.
— The third factor is the recognized open API, a little more technical, and spend time in another study, we can first look at the examples: amazon, flickr, such as google map.
Web application from the product / service producers point of view, how to create Web 2.0 products? It is important to seize such points is a micro-content (here defined), one individual users. Apart from these two basic, could also be considered within the community as well as the sharing of API.
Micro: English is microcontent. Produced by any user data is micro-content, such as a blog, comments, pictures, collection of bookmarks, the list of music preferences, want to do things, want to go places, new friends, and so on. These micro-content, full of our lives, work and study, the number of its importance, and we rely on it, and inferior to those Daomaoanran, up by orthodox papers, theses, books.
On the contents of the re-discovery and use of the Internet by the start of equality, democracy, freedom of a natural derivative, is the Internet-related information technology management cost reduction after an achievement.
Every day we produce numerous micro-content and consumption with the same number of micro-content. The Web 2.0, how to help users manage, maintain, store, share, transfer of micro-content, a critical.
Individual users. Web 1.0 for the typical product / service, users do not have a specific look, personality, it is only a fuzzy synonym for groups only. But for Web2.0 products and services, the user is a real person. Web 2.0 service, is a specific person, rather than as a ghost-like concept. In addition, the specificity of this person, because services will be constantly enriched themselves up.
How to specific individual services, Web 2.0 is the starting point for design.
Therefore, a class can be called Web 2.0 products / services will be this:
Individual users of the service in the collection of micro-content, the creation, publishing, management, sharing, cooperation, the maintenance of the platform.
Other? I am afraid that some people in the design mentioned in the contents of the XML-performance micro-content polymerization; micro-content migration; the maintenance of social relations; interface ease of use and so on.
And whether it is open source, participation, personal values, the grassroots, cooperation and so forth?
Web2.0 is many times and mutual implicated beginning of a new phase of the arrival. Therefore, different people have different views. Well, for Web developers, Web2.0 What does it mean?
They said that Web2.0 stage, is a Web platform, or that the Web is becoming programmable, Web applications can be implemented. Careerist envisage that the ultimate goal of this it is the Web OS.
Web 1.0, the Web is a read for the release of the platform from one of the Web hypertext links from. Now the trend has changed, Html Web is not just the domain of documents, it became interactive sites.
Web 2.0 Conference website banners Jeff Bezos quoted as saying "Web 1.0 is making the internet for people, web 2.0 is making the internet better for computers."
Specifically, they say Web as a development environment, with Web services provided by the programming interface, the website has become software component.
These Web Service is the goal bar, isolated islands of information through these Web Service dialogue, freedom can be constructed for different applications to the building.
Some examples: del.icio.us, flickr, a9, amazon, yahoo, google, msn provide programming interfaces derived from a variety of applications.
Why should we open APIs, which involved in the commercial market for technical strategy. Of course, there are more profound reasons, then, what is it?
This is not only reflected in the different interactive website services, but also embodied in between users and Web browser interaction. This is why delicious bookmarks in the collection and AJAX Web2.0 one of the reasons why so relevant.
Web pages in the use of desktop procedures to facilitate some of those really enjoyed things. I am afraid this is a programmable Web, Web pages and content is no longer marked as a simple mixture, it can be programmed is a place (this is understood?)
Some people objected that the use of AJAX search engine unfriendly, only the director of Web1.0 only concerned about this bar, in the Web 2.0, the station should be concerned about is the involvement of users convenient, user freedom, as search, have RSS / ATOM / RDF, etc., do not need to worry about this, Google has not conform to the trend so that the initiative submitted?
Programmable third, it is Web applications and desktop applications seamlessly link between the trend? Said here similar to the "tools, from Internet browsers to various browsers, such as rss reader content development"
Programming One of the purposes of the operation of the data, therefore, the site, in addition to Web Service Interface, for the simple way is the last content to RSS / RDF / ATOM format, or meaningful XHTML format output, at the same time the content and performance of the separation.
Web2.0 is a history of the concept, rather than a technical concept, it is the historical development of Web dating results. On the concept of the order, help me to better grasp the Internet is happening in technology and culture.
Chinese blogs circle talking about Web 2.0 Abstract:
— "Web 2.0 is used to study the phenomenon and found that the laws of things, not be used to attract businesses and investment, Dasichanghu things. When more and more Internet applications to interact with users, more and more content is generated by the user , a growing number of Internet users to participate in the process of creation when in fact it represents a new trend of thought.
This trend of thought, some of the new technology beginning to emerge, some old technology renewed vigor. You casually express how such a phenomenon, but the phenomenon itself is real existence, regardless of the call Web 2.0, or community of the Internet. "[Keso: old run to the Web 2.0 pouring a bucket of cold water]
— "I think that the most valuable one is that the web application data formats to exchange began gradually appearing in the" standard "… these standards … more easily be automated processing machines … can help people better filter and customize information.
Second, more services will be in the form of web service to provide … This makes web services can be integrated each other, the result was the birth of more new services … the importance of being improved. More attention in the past web information, and now more and more people use more attention, the so-called "social." In addition web improve the availability of more and more attention is being run …"[ old: North Korea poured cold water on web 2.0]
— "I think the Web xx is designed to differentiate between people of different times and the development of Web use, and these concepts are also summarized the results after. Seize the right direction, as mentioned in the Wikipedia towards interactive and in the direction of social networks, regardless of what technology, as long as it can achieve their goals are good. even as general users, can not ignore Web xx discussion, because we have been in the use of these technologies or the website. "[Library perspective: Web 2.0]
— "RSS online content providers gradually become the standard of service distribution platform. Blog, as well as user-generated content of the rise. RSS My Yahoo provide integrated services. At the same time, which is closely watching the development of a number of areas, including search technology, personality , User-Generated content (including blog, comments, images and sounds), music, video and short Accessibility (easily accessible) "[Owen: Mary Meeker for the new - About Digital World Development Report of the removal]
— "We are talking about Web2.0 brought us is a read-write the network, which can read and write in user network performance is a dual-channel modes of communication, that is pages and the interaction between users from the traditional "Push" mode evolved into a two-way exchange of "Two-Way Communication" model. while for the development of Web services are concerned, the idea is Web2.0 services affinity, workability, and user experience and availability . "[Owen: BaCKpACK-experience can read and write Web services]
— "Web 2.0 is a distributed information can be outlined, a web document is formatted web data. We will not see different to the old information, and now we have noted is a polymerization, then mixed content tool." [ songzhen: also said that the translation of Web 2.0]
— "From these applications can be seen: If based on the traditional HTML, to achieve the same function will be very complex and unstable, and the exchange of data reproduction cost is very high. Therefore: RSS this standard to be eventually contribution is made Most of the Internet sites become programmable: there are similar examples in the Blog: TrackBack Ping, and other mechanisms that are dependent on XML / RPC realized. Lucene original design of a RSS / XML interface also to the mind, it makes full-text retrieval services can be easily embedded in a variety of applications through the various elements of keywords between richer Association (Well Referenced). "[trucks East: RSS, a simple agreement makes programmable Internet ]
— "RSS, as well as the possibility of how to better polymerization (usually, the better polymerization should be based on personal knowledge management and interpersonal management) should be very clear that a new generation of web2.0 or one of the core structure. Moreover, you will reconsider that happens to be dispersed led the polymerization, dispersion polymerization promoted through polymerization of thinking, the Internet is becoming increasingly network-rich and intensive, web2.0 becomes more and more interesting, it will web1.0 that the era of huge nodes digestion portal constantly to strive to create a more harmonious natural network map. "[Horse: rss, polymerization of the countless possible]
— "The new web2.0 sites rely on user participation, user-driven, user-building." [Horse: The term Web 2.0]
— Keso: Web 1.0 and the difference between Web 2.0
— "Outwardly, Bloglines replaced the gateway to become a new centre, but there is one major difference. Portal is read-only, with a lock of the nature, you can leave the portal, but you can not take away portal content. Bloglines is completely different, do you think it useful, it will continue to use, one day you no longer like Bloglines, you can export your OPML, to another
RSS subscription site, or simply use the same client software to the content. Therefore, such as Bloglines site, we can write, you can import, but also can be exported. As you have the right to choose the information, the service provider also has the right to choose, no one can lock you that the initiative in your own hands. "[Keso: repeat information the right to choose]
— "Flickr, del.icio.us, such as Bloglines Web 2.0 service, through open API received a lot of interesting and useful ideas, and with external forces to allow users access to a better experience. More large companies have joined to open API trend, Google, Yahoo!, Amazon, Skype. Google Desktop Search in March of this year only open API, quickly generated a great deal of creativity, can be greatly expanded the search file format. "[Keso: Open API]

— "I think there are several aspects of Web2.0 features: personality of the mode of transmission. Read and write both means of expression. Socialization of the joint approach. Standardized creative way. Convenient way of experience. High-density media way. "[Fei Ge: Web2.0 and future network]
— "RAILS written by the website of a typical reader network features: RAILS created in the framework of the three ACTIVE RECORD this module, if you read it is the most important base class ActiveRecord:: Base, you will find that there are CREAT, EDIT, SAVE, DESTROY these methods have included a natural, and this realization of a database CRUDS becomes so simple. these categories and Web pages directly mapped to the name together, which makes its own website can be like a Editors of the database data.

"[Don: explain the concept of Web 2.0]
Web 2.0, an important feature of the stage is open, and the early Web is very different from the opening, following several prominent features:
Content
— Content Creation share authorization. Its broad-spectrum and choice, it is sufficient vitality. CC in the first-ring network is widely used, but many commercial companies have also adopted CC means (such as BBC); First World use of text, then gradually extended to the world of multimedia, such as audio, video, Flash animation, and so on. A culture of freedom (free culture) movement in all aspects of quietly spreading.
— Open source content. And the early stage of the Web compared to the use of related equipment to reduce the cost of using technology to reduce the threshold, and people are free to produce and publish all kinds of content, such as text information, such as voice recording, such as video recording, etc.. The production and dissemination of information is no longer commercial capital or technology elite privileges.
A new stage of the Web, in the original commercial, technical and public information between the production and dissemination of the gap was削平. Monopoly and to remove information centre has become possible. Not only that, the information production and consumption patterns have also changed from the original production / consumption confrontation has become a participatory information fairs.
The main aspects of Web
— Commercial websites have also gradually adopted an open, participatory model. Apart from the content of a mandate from the CC. Not exposed the contents of the original, with the blog, podcasting and opening to the outside world, such as the rise. Some websites are still open technical aspects, such as open-source, for example, open APIs (programming interfaces) to allow themselves to become a platform for users to take part in the creation of derivative products, the users themselves are products producers.
Not only is the content of the technical level, in encouraging the participation of users, as well as the opening up of the corresponding emergence of a number of news websites such as the source of the RSS output, quoted a circular (trackback) capabilities adopted, blogthis facilitate the provision is to allow users to participate in All to the contents of the production, dissemination of the various links.
— Personal information at the opening. Openness, the exchange can only social behaviour and patterns. Personal content with the opening up of a class of the rise of the Web2.0 services. It covers the content (text, voice, images, video), the relationship between behavior and so on.
