- A web portal is a website that offers various services through a centralized interface. Today, most organizational websites are portals.
This article only aims to provide a short overview and refers to other articles in this wiki (e.g. you may follow the links in typology section).
We may classify portals according to these three dimensions:
- Information portals: e.g. news, knowledge
- Transaction portals: e.g. sales, registration
- Collaboration portals: e.g. file sharing, discussion
3 Most popular kinds
This is not a strict classification. Some of the entries may also have traits from other categories. In particular, business or educational organizations may centralize all services in some kind of "vertical portal" (with various access rights).
- Large Internet access portals, such as Yahoo or MSN
- Information portals such as CNN
- Participatory information portals such as Slashdot
3.2 Expertise and knowledge portals
- Experience sharing portals such as epinions
- Collaborative encyclopedias such as the Wikipedia
- (Specific) knowledge management portals
3.3 Commerce and service
- Commerce Portals, such as Amazon
- Service portals, such as Swiss railways
- Commerce and service portals also can be categorized as a combination of "B2x" portals:
- business-to-employee electronic commerce (B2E) portal
- business-to-consumer (B2C)
- business-to-business (B2B)
- business-to-dealer/distributor (B2D)

- Learning management systems
- Community of practice portals such as the TECFA portal
- Community of interest portals such linux.

4 Technology-based typology
- "Heavy" portalware (to build enterprise or global university portals, etc.)
- Content management systems
- Learning management systems (LMS)
- C3MS (Community portals)
- Blogs (at least some that contain more than just diary entries)
- Knowledge management systems
See the list of portalware.
- Most open source portalware is based on some sort of LAMP architecture, but java-based architectures are also popular (in particular within computer science communities). See individual entries in the technology-based typology above.
- Enterprise portals probably rely mostly on some java-based technology, although the Microsoft .Net architecture is gaining in popularity.
5.2 List of portalware
- Web services
- Transport, e.g. HTTP
- XML-based messaging, e.g. XML-RPC, SOAP or REST
- Service description, e.g. WSDL
- Service discovery
- In the Java World:
- Data standards
- In DSchneider's opinion, there is a blatant lack of data standards, e.g. it is very difficult to move data from platform to an other.
- In education, various IMS standards try to address this issue.
