Information

The physical world is writable

(in some sense)

Our brains are writable

And we (programmers) have looked after our own needs pretty well

A magic trick

The database with the heart of a wiki?

Information model

Objects with tags (with values)

Objects have no owners

A permissions system on tags

Tags organized into namespaces

A simple query language

Queries

Numeric: tag value (=, <, etc.)

Set contents: tag contains “great”

Exclusion: price > 20 except rating < 3

Tag presence: has tag

Grouping/logic: (...), and, or

Textual: tag text match (coming!)

Permissions

For each action on a namespace or tag:

There’s a policy: ‘open’ or ‘closed’

And a (perhaps empty) list of exceptions

API

HTTP / REST based

JSON arguments & replies

A dozen client-side libraries (Python, Perl, Ruby, .Net, Java, etc)

Other APIs planned (XMPP, Thrift)
