-This should get us 80% there:
-
-An open source, crytographically secure, transparent to the user, distributed platform for creating,
-maintaining, and selectively sharing profile information (e.g., a marketplace for anonymous
-demographic profiles)
+The goal of this note is to focus on the exact minimum requirements of an
+OpenPrivacy system, particularly given the existence of similar supporting
+technologies such as Mojo Nation, Freenet, and KeyNote.
+
+Background
+
+Mojo Nation, Freenet and Publius provide anonymous, censorship-resistant
+publishing of files
+
+In addition, Mojo Nation provides a reputation system that provides feedback
+for publishers, servers, and search engines.
+
+KeyNote provides a formal mechanism for describing actions, principals,
+credentials and policies.
+
+Foreground:
+
+OpenPrivacy requires:
+
+ + anonymous publishing of profiles
+ Note: censorship-resistant publishing is desired but not mandatory
+ How does the user profile information get into the system?
+
+ + a generic profile format (an extensible XML schema)
+ where profiles have:
+ + an anonymous/pseudonymous owner (e.g., a pubkey/credential)
+ + a payload (XML/MIME data and/or pointers to other profiles)
+ + a manifest of signed parts
+ + an immutable MD5 (SHA1?) signature/checksum
+ + a mutable profile/reputation accumulation mechanism
+
+ + a profile storage mechanism
+ + operated by an "agent"
+ agent may have requirements like expire date, reputation, etc.
+
+ + a query mechanism for profiles (a capability)
+ e.g., to find a match against a desired demographic
+
+ + a mechanism for attaching notes to profile
+ e.g., a "contact me" message which may contain an offer
+
+ + a mechanism to strip or clean a profile of notes
+ e.g., of certain types or (negative) reputations
+ (stripping of notes is deemed easier than disallowing their attachment)
+ note that storage agents may regularly strip expired profile info
+
+Q: can I strip a negative reputation?
+A: yes, but only from a profile I own
+ (e.g., someone else can carry a negative reputation for me
+ that I can do nothing about)
+ therefore, positive reputations (or lack of them) are generally more
+ useful measures of a profile's worth.
