Exploring open source licenses

A presentation to remind me on the (well-known) licenses out there.

Addendum:

1. License for SaaS. AGPL (v1 and v3) are two copyleft licenses that cover this. Again, the rationale behind them is to be able to provide source code for software being used over the web. v1 is very similar to GPL v2 and v3 is on the lines of GPL v3.

2. EPL. A business-friendly license having weaker copyleft license than GPL. Not compatible with GPL and hence a work combining GPL and EPL cannot be redistributed. EPL requires distribution of a separate license (hence not very much in the free spirit) for the original work in the software which are supported by patents. EPL also contains a patent-retaliation clause which causes the contract between the author and user to terminate when the user initiates a lawsuit for patent infringement against the author.
