Definitions can be used, as in the Free Software and Free Culture definitions, to highlight network services that meet a standard of freedom.
Summary of current practices
OSD: Open data (private data only open to the user it's about) and public free software.
FOSD: this is more of a brainstorming/reference page than a definition; the draft definition produced from that process has been mailed to the mailing list and if someone nags me I'll put it on the web somewhere :)
Open issues
- What do you do about Googlejuice?
- What do you do about identity?
- Are external dependencies permitted?
- Ease-of-install requirements?
- Interoperability requirements?
- Requirement to share aggregate/anonymized user data?
