Introduction

Defining and organising equipment is a rather complex matter, not only do we have a tree of different types of equipment, very generic, to very specific. We also have the types, the serially produced equipment with a type number and manufacturer. And we have the unique physical piece, for example part of a collection. Each of these levels require specific properties to describe their uniqueness.

An example 

In the equipment tree, we find 
* lighting equipment 
** Lighting fixtures 
*** conventional lights 
**** lens spotlights 
***** Fresnel spotlights
These are "generic descriptions"

An ADB Europe F101 is a specific type of Fresnel, it is a "type" of which a whole series is made.

And the Europe F101 in the collection of a theatre museum is a "unique piece". It is one out of a series that is produced.

To be able to grab the whole physical reality of our world, we use a verry wide definition of "equipment" which includes for example

  • tools for hair dressing
  • accessories for make-up
  • cables
  • parts of equipment
  • soft goods
  • all kind of tools

In fact, everything that is "physical" and is "used" in the theatre- or eventindustry is described as equipment in Canonbase.

Information on specific types of equipment

Describing different types of equipment requires specific properties for each type. The general properties for equipment are detailed in this page, but for detailed descriptions of equipment, we made different pages, listed here.

General properties for equipment

Header

Label*

  • The name of the equipment in it's original language
  • We do not translate this, except if the business itself uses different names in different countries.

Dates

Dating of equipment

Putting exact dates on equipment is a complex and difficult task. Manufacturers don’t put dates on catalogs or publicity documents often, probably because it would make the equipment old fashioned in the eye of the buyer. Most equipment does not have a production date on the equipment.

Of course we know that it can not have been made before the manufacturer exists, except for some equipment that was the cause of setting up a company. And the equipment can’t be produced after the manufacturer stops his activities, even if some companies are taken over with their production.

To narrow down the time span of production, we have a series of sources:

  • Publicity or promotion in magazines, often the equipment is promoted at the launch.
  • Presence at trade fairs or world fairs.
  • Dated Version numbers on manuals or similar documents.
  • For more recent equipment, dates on printed circuits.
  • Occurrence in articles about theatres building descriptions.
  • Occurrence in bids or bills for sales of equipment.
  • Occurrence in plans, plots, lists or other production information.
  • The lay-out of labels, but sometimes a company overlaps labels once an appliance is in production).
  • Comparison with equipment that is dated and occurs in together in a publication.
  • Occurrence in books, but the accuracy is lower because the slow process of writing and publishing.
  • Changing telephone number formats on documents.
  • Telephone numbers or addresses on the documents.
  • Comparison of serial numbers for unique equipment.
  • The use of specific parts or technologies, for example lamp types, plugs, …
