[foaf-dev] RDFAuth: an initial sketch

My mail was a little tongue in cheek, since the conversation about making F=
OAF useful today for interchange of contacts and localized endorsements bet=
ween social network members had been discussing the relationship between th=
ermodynamics and triples - and the laws impact on any and all triple cachin=
g frameworks. One might as well add a little quantum entropy into that disc=
ussion to heat it up a bit more.

On a more pragmatic note, consider the proposed relationship between OAuth =
and SAML2 http://rnd.feide.no/content/proposal-perfsonar-oauth-profile.

I've already widely discussed that from SAML2 I've bridged to OpenID2. Thus=
, by transitivity, we have OpenID2 to OAuth easily deployable. As I am now =
actively investigating which authorization framework to apply to our busine=
ss (considering OAuth and XACML) this is all timely. By default, US realty =
will be deploying SAML tokens over SOAP web services for both authentiation=
 and authorization, to access a US national RDF/XML data service,  within a=
 year. But there is plenty of leeway politically - to also add RETS/OAuth t=
o the pot. Provided the various bearers are transfering the same payload me=
ssages, different endpoints can exhibit different doctrines of how best to =
interact with certain types of semantic web user agents. Different security=
 frameworks can be in operation - provinding there always lies the opportun=
ity to account link identifiers or translate the various tokens blobs.

Hi Peter,

Yes, quantum security is perfect in the theoretical sense but W3C cannot =

enforce users to buy *any* kind of special hardware to make the web =

works, expensive or cheap. There are fingerprint scanners widely =

available and still we don't see any standard requiring them to work.

Standards work on a different level, by defining which level of trust =

you must rely on each part of the system. What you use to assure that is =

up to the implementation.
