Peering for Fun and Profit
Xpertweb users equip each other to use peering protocols. By peering, we mean that every participant has their own Xpertweb server, located on any ISP that offers PHP support. Xpertweb users have tools to set up a new user by using any FTP client to upload a script that sets up a new site. This seemed a pretty dramatic and excessive requirement when we first specified it, but blogging and grandkid picture hosting is making a personal web site less controversial.
Digital ID is very hard when you’re relying on a central server to authenticate people. It becomes trivial when each participant has exclusive control over their own website and easy-to-use forms to administer their ID info.
Peering means Peering
If you and I are peers, we allow each other to peer into our lives more than we allow others (ain’t English a fun language?).
Each Xpertweb user has an ID file (like, me.xml) on their site, containing the usual fields (required) and any other optional fields the owner might want to selectively expose to:
Using the W3C XML Encryption spec, any of the owner’s data may be encrypted at the field level, and even the names of the fields/tags may be encrypted.
Trusting the casual visitor
All Xpertweb vendors want the world to know about their skills, reputation, products and, probably, thoughts and ideas on their blogs. Those are all published as broadly as possible, with skills and products organized into an Xpertweb index. The blogosphere is demonstrating that we crave notice more than we fear exposure.
However, Xpertweb vendors only want to transact with others having a proven reputation since, like a waitperson, the vendor’s compensation is subject to the buyer’s rating of their work. So here’s our homegrown digital ID sequence, assuming a vendor whose unique ID happens to be FFUNCH and a shopper with BRITTB as a unique ID (gross simplification in effect–unique IDs are hard but possible).
It may not be perfect, but it’s close enough for FFUNCH and BRITTB to proceed with a transaction, whether it’s reading a blog for $.06, trying a $15 shareware, ordering a $75 Afghani carpet or paying a personally negotiated $10,000 retainer.
Because each product has different requirements, BRITTB’s site can selectively expose needed information, like a physical address or website admin info.
