Web 2.0 learning note

[Introduction] starting from the web history, the Web 1.0 era, which originally dominated by static publishing pages, has evolved to the Web 2.0 era with stronger dynamic interaction,ArticleThis section describes how to understand and learn about Web 2.0.

The history of web is very important. The learning of a technology should also start from history and form Historical Changes in time to know the status quo and even predict the future. What is Web 1.0? Do they remember the WWW era of static html? (In that era, how did WWW applications, people's Web experience, and their impact on society ?) What is the version of Dynamic HTML compared with the web in static html? 1.5? By the way, they call it true. (In terms of effect and impact, how much is extended and deepened compared with 1.0 ?) The data to be presented is stored in the database.ProgramIn response to user requests, extract data, and add a pre-designed template to dynamically generate htmlCodeTo your browser. This is the 1.0 series. It should be the same as Web 1.0 seen in the browser. It has a 0.5 update, because the data is not created and released in advance, but is dynamically generated, interaction with the user's needs. Well, I am adding 0.5 to Web 2.0. Where is the change? (How can we continue to change the Internet and society as we see the rise and changes ?) Update: for the differences between different versions, see the Amazon example. Something is not so lucky. Web 2.0 is not a specific thing, but a stage. It is a name for various technologies and related product services that contribute to this stage. So we can't say what Web 2.0 is, but we can say that those are Web 2.0. These conditions are listed under the Web 2.0 entry of Wikipedia: * CSS and semantic-related XHTML Markup * Ajax technology * Syndication of data in RSS/atom * Aggregation of RSS/atom data * Concise and meaningful URLs * Supports publishing to Weblog * Restian (preferred) or XML WebService APIs * Some social network elements The following elements must be met: * The website should be able for users to move data inside and outside the website system. * Users have their own data in the Website System * Completely web-based, and all functions can be completed through a browser. (The above content is referenced in Wikipedia in English version) Although this is just a statement of the family, we are still recognized for the several elements mentioned in it. -Synchronization, aggregation, and migration of XML data based on RSS, Atom, RDF, and foaf. Data is no longer mixed with pages and websites. It is independent and follows the user. This is an important feature of Web 2.0. This is why blog is represented by Web 2.0. In wangzhi, the main character is an independent website. Independent, and then physical performance. Now, we can make them active. By processing XML data, the content can be freely combined and presented and processed by various applications, such as web programs and desktop programs. (Updated: see all your info in one place in Business Weekly) Of course, the most important thing is the people behind it. -Social factors. Content follows people, and the content can be freely combined by users. That is to say, users can freely create communities with the help of content media, and various social (network) behavior occurs. In addition, there are labels and folksonomy built on the open tag system. -The third accepted factor is the open API, which is a little more technical and takes another time to study. You can first look at the example: Amazon, Flickr, and Google map. (Web 2.0 is a large basket with many things installed) From the perspective of Web application products/service producers, how can we create Web 2.0 products? It is important to grasp the following points: Micro content (defined here) and user individual. In addition to these two basics, you can also consider sharing in the community and providing APIs. Microcontent: microcontent. Any data produced by a user is classified as micro-content, such as a blog, comments, images, favorite bookmarks, favorite music lists, and what you want to do, places to go, new friends, etc. These micro-content is filled with our life, work, and learning, its quantity, importance, and our dependence on it, it is no less than the Orthodox articles, papers, and books that are well-founded and well-styled. The re-discovery and utilization of micro-content is a natural derivative of equality, democracy, and freedom created by the Internet. It is also a result of Internet-related technologies that cut information management costs. Every day, we produce a large number of micro-content and consume the same amount of micro-content. For Web 2.0, how to help users manage, maintain, store, share, and transfer micro content becomes the key. User individual. For typical products/services of Web 1.0, users have no specific appearance or personality, and they are just synonymous with a vague group. However, users are real people for products and services of Web2.0. Web 2.0 serves specific people, rather than a concept like a ghost. In addition, the uniqueness of this person will be enriched by the service itself. How to serve this specific individual is the starting point of Web 2.0 design. Therefore, a type of product/service that can be called Web 2.0 is as follows: It serves as a platform for collecting, creating, releasing, managing, sharing, cooperating, and maintaining personal micro-content. Some people have mentioned the XML Representation of micro content, the aggregation of micro content, the migration of micro content, the maintenance of social relations, and the ease of use of interfaces. In essence, it is open source, participation, personal value, grassroots, cooperation, and so on.
