What is Web 2.0? Nowadays, almost everything is “tagged” as Web 2.0. Companies, sites, ideas, etc. So, as teh old saying goes, if everything was Web 2.0,  then nothing would be Web 2.0.

Web 2.0 refers to a generation of internet applications. The ones shifting the importance from the server and the “deux ex-machina” content creator, to the end-users and their clients. Wiki tells us the phrase “Web 2.0” hints at an improved form of the World Wide Web. Technologies such as weblogs, social bookmarking, wikis, podcasts, RSS feeds (and other forms of many-to-many publishing), social software, web application programming interfaces (APIs), and online web services such as eBay and Gmail provide a significant enhancement over read-only websites. Stephen Fry (actor, author and broadcaster) describes Web 2.0 as “an idea in people’s heads rather than a reality. It’s actually an idea that the reciprocity between the user and the provider is what’s emphasized. In other words, genuine interactivity if you like, simply because people can upload as well as download”. The phrase “Web 2.0” can also refer to the transition of websites from isolated information silos to interlinked computing platforms that act like software to the user. Web 2.0 also includes a social element where users generate and distribute content, often with freedom to share and re-use. The result is a rise in the economic value of the Web as users can do more online.

Earlier users of the phrase “Web 2.0” employed it as a synonym for “Semantic Web”. The combination of social-networking systems such as FOAF and XFN with the development of tag-based folksonomies, delivered through blogs and wikis, sets up a basis for a semantic web environment.

Tim O’Reilly regards Web 2.0 as business embracing the web as a platform and utilising its strengths (global audiences, for example). O’Reilly considers that Eric Schmidt’s abridged slogan, don’t fight the Internet, encompasses the essence of Web 2.0 — building applications and services around the unique features of the Internet, as opposed to building applications and expecting the Internet to suit as a platform (effectively “fighting the Internet”).
On September 30, 2005, Tim O’Reilly wrote a piece summarizing the subject. The mind-map pictured above (constructed by Markus Angermeier on November 11, 2005) sums up the memes of Web 2.0, with example-sites and services attached.

In the opening talk of the first Web 2.0 conference, Tim O’Reilly and John Battelle summarized what they saw as key principles of Web 2.0 applications:

– The web as a platform
– Data as the driving force
– Network effects created by an architecture of participation
– Innovation in assembly of systems and sites composed by pulling together features from distributed, independent developers (a kind of “open source” development)
– Lightweight business models enabled by content and service syndication
– The end of the software-adoption cycle (the so-called perpetual beta)
– Software above the level of a single device, leveraging the power of the “Long Tail”
– Ease of picking-up by early adopters

Tim O’Reilly provided examples of companies or products that embody these principles in his description of his four levels in the hierarchy of Web 2.0-ness. Level 3 applications, the most “Web 2.0”-oriented, which could only exist on the Internet, deriving their power from the human connections and network effects that Web 2.0 makes possible, and growing in effectiveness the more people use them. O’Reilly gave as examples: eBay, craigslist, Wikipedia, del.icio.us, Skype, dodgeball and Adsense. Level 2 applications, which can operate offline but which gain advantages from going online. O’Reilly cited Flickr, which benefits from its shared photo-database and from its community-generated tag database. Level 1 applications, also available offline but which gain features online. O’Reilly pointed to Writely (now part of Google Docs & Spreadsheets) and iTunes (because of its music-store portion). Level 0 applications, which would work as well offline. O’Reilly gave the examples of MapQuest, Yahoo! Local and Google Maps. Mapping-applications using contributions from users to advantage can rank as “level 2”. Non-web applications like email, instant-messaging clients and the telephone.

These are some leading European Social Networks, as described by their own creators:

Grono.net: “grono.net is a site, which gathers people belonging to a closed community, in which you may find your friends and collegues – and they may find you! Our system registers your contacts and shows who – through your existing contacts – may become your friend, and which is the shorthest path between you in the chain of friends. At the same time, you have as much privacy as you want – you decide which data or personal information you want to show the others. To register in our community you have to have an invitation from someone who is already our member.”

Neogen.ro: “portal de joburi, matrimoniale, cluburi, network, stiri, anunturi, publicitate, catalog, jocuri multiplayer, hosting, monitor, albume foto, content mobil si multe alte produse si servicii online pentru consumatori si firme.” More or less: portal for work, weddings, clubs, sites, classifieds, etc.

NetLog: “Netlog is an online social portal specifically targeted at the European youth. It is developed by Netlog NV, the Belgium-based publisher of popular online social media. Netlog has more than 26.2 million members throughout Europe. Netlog is currently available in eight languages – English, French, Spanish, German, Portuguese, Dutch, Italian and Romanian – with all other European languages to be added in the near future. n Netlog, members can create their own web page, extend their social network, publish their music playlists, share photos and videos, post blogs, join groups called ‘clans’ and much more. It is thus the ultimate tool for young Europeans to connect and communicate with their social network.”

A Mashup is an applications combining and merging information in ways which may, or may be not, be the ones intendend by the site(s) where the information where collected in the first place. With mashups, the focus shifts from the application to the information which populate it. To make it brief: information rule 🙂

Hip-hop lent this term to Web 2.0, because originally mashup meant to produce a new song by mixing two or more existing pieces. As Wiki says, mashups currently come in three general flavors: consumer mashups, data mashups, and business mashups.

The most well-known type is the consumer mashup, best exemplified by the many Google Maps applications. Consumer mashups combine data elements from multiple sources, hiding this behind a simple unified graphical interface.

Other common types are “data mashups” and “enterprise mashups“. A data mashup mixes data of similar types from different sources, as for example combining the data from multiple RSS feeds into a single feed with a graphical front end. An enterprise mashup usually integrates data from internal and external sources – for example, it could create a market share report by combining an external list of all houses sold in the last week with internal data about which houses one agency sold.

A business mashup is a combination of all the above, focusing on both data aggregation and presentation, and additionally adding collaborative functionality, making the end result suitable for use as a business application.

Mashups and Portals are both content aggregation technologies. Portals are an older technology designed as an extension to traditional dynamic web applications, in which the process of converting data content into marked-up web pages is split into two phases – generation of markup “fragments” and aggregation of the fragments into pages. Each of these markup fragments is generated by a “portlet”, and the portal combines them into a single web page. Portlets may be hosted locally on the portal server or remotely on another server.

Portal technology defines a complete event model covering reads and updates. A request for an aggregate page on a portal is translated into individual read operations on all the portlets that form the page (“render” operations on local, JSR 168 portlets or “getMarkup” operations on remote, WSRP portlets). If a submit button is pressed on any portlet on a portal page, that is translated into a single update operation on that portlet alone (“processAction” on a local, JSR 168 portlet or “performBlockingInteraction” on a remote, WSRP portlet). The update is then immediately followed by a read on all portlets on the page.

Portal technology is about server-side, presentation-tier aggregation. It cannot be used to drive more robust forms of application integration such as two-phase commits.
