[pd-discuss] Flowchart based Public Domain calculator API call

Mon Feb 15 10:13:05 UTC 2010

A backing database would be a good idea, it could certainly help in accuracy.

Today I am trying to encode the Dutch flowchart to XML, and I found an exception that does not fit our static encoding of document types.
In the documentation we now have these types for a given work: 

	LITERARY = "text"
	SOUND = "recording"
	PHOTO = "photograph"
	VIDEO = "video"
	DATABASE = "database"

The dutch, as do many jurisdiction(?), state that laws and decrees are a special type, immediately falling in the public domain. Should we add a type
LEGAL = "legal" to differentiate this type?

Kind regards,

Maarten Zeinstra
