Dear all

I apologize for this not being about maritime but it's taken a while to work
on this one.

This is the proposed structure for a period related thesaurus. We've
constructed a draft copy along these lines.

There are 4 top terms (or in EH parlance CLASSES)

ARTISTIC PERIOD
Covers periods which can be defined by the artistic style of architecture or
artefacts eg. BAROQUE, ANGLO SAXON, ELIZABETHAN.

CULTURAL PERIOD
Covers periods which relate to technological or cultural change and includes
the classic 3 Age system as well as the later "cultural" periods of ROMAN,
MEDIEVAL, MODERN etc.

HISTORIC PERIOD
Covers periods that relate to a specific slot in time Eg. Centuries, Major
historic events.  Presently this covers the 1st  to the 21st  Centuries AD.
Each Century has narrow terms eg. 11TH CENTURY AD has the Narrow Term of
NORMAN CONQUEST which in turn has the Narrow Terms of BATTLE OF HASTINGS and
the BATTLE OF STAMFORD BRIDGE.
	
>From the 16th Century onwards each century is split into EARLY, MID and
LATE.

POLITICAL PERIOD
Covers periods defined by the reigns of emperors, monarchs or parliaments.
This presently includes all the Royal Dynasties of England and (after 1603)
Scotland, as well as Political Leaders such as SIR WINSTON CHURCHILL, OLIVER
CROMWELL


The main relationships between the four classes will be defined by the
Related Terms of any given term.

Eg. If you are interested in the BATTLE OF BOSWORTH FIELD

You may also be interested in HENRY VII, RICHARD III, or the TUDORS

It's finding a way of linking the four classes so that you get the maximum
information out.

I apologize for the historic bias but we're trying to tie it in with the
National Curriculum. 


As I say it's only a draft so please feel free to shoot it down in flames.

I've placed a copy of the draft CLASS listings as well as a few examples of
terms and their associations in the archive for the fishen site. You can get
these by sending the following two line command
as the only text of a message to [log in to unmask]
<mailto:[log in to unmask]> 

get fishen alpha.txt (or time.txt)
stop

I look forward to any comments (either direct to me or via this forum)
