Implementing a REST workflow using JSON Schema, an example

The problem domain

You are designing a document-control system. Users create and edit documents for publication. Documents can be draft, in review, on hold, in process, or published. Users have specific roles which determine which documents they have access to, and what they are permitted to do to the documents, as the documents move through the workflow. Some users are writers, others are editors.

Expressed in plain language, the rules are:

• Writers can view their own documents regardless of status.
• Writers can create new documents.
• Writers can save new documents as draft, or to in review if certain information is included.

• update metalsmith plugins for metalsmith 1.x

30 Jan

• json-schema-*: consider a different implementation strategy that makes "core" less core:
• does not require pre-parsing the schema in order to dereference and validate
• allows pluggable validators through a common interface, with a default validator
• parses the schema only when building a correlation, which is where it is actually used
• correlation prototype is extendable, as now, through a plugin interface
• "model" functionality is implemented as a correlation plugin

# Usage:
#   ruby sequel_dot.rb [SEQUEL-DATABASE-URI] > output.dot
# Or pipe directly to Graphviz:
#   ruby sequel_dot.rb [SEQUEL-DATABASE-URI] | dot -Tgif > output.gif
#
# Note adapted from Jeremy Evans' and Rohit Namjoshi's son's code at 
#   http://sequel.heroku.com/2010/05/29/fun-with-graphviz-and-associations/
#
# However, instead of basing graph on model associations, this uses foreign key constraints of the db tables
# Thus, this relies on the database adapter supporting #foreign_key_list.

2. Array() top-level function works on any Enumerable
