This is a list of services that might be considered "open" under various proposed definitions of "open" services, useful to test various arguments about what such a definition should or shouldn't contain.
- Wikipedia: data and software are freely available. How are APIs licensed?
- geonames.org
- hostip.info
- gmail: server source is proprietary, but all (email) data is available via standardized/open protocols, and users can make the service transparent (from an identity perspective) by using other email addresses.
- Amazon EC2: server images are ~ standard xen images. If you can move your data and computation transparently between S3 and completely Free xen-based servers, is it open/free/autonomous service?
- GNU Savannah:
- Second Life: client is Free; service is not.
- audioscrobbler/last.fm:
- altlaw.org:
- chicagocrime.org (defunct): what happens when you mash up Free data with non-free services like google maps?
