What data is there?

Each row in the CSV file is an object from the catalogue, and has a number of fields. There are:

id_NUMBER:
a unique identifier
ITEM_NAME:
a simple name, often from an established thesaurus
TITLE:
a short caption
MAKER:
the name of who made the object
DATE_MADE:
when the object was made, which may be a range, approximate date or unknown
PLACE_MADE:
where the object was made
MATERIALS:
what the object is made of
MEASUREMENTS:
the dimensions of the object
DESCRIPTION
a description of the object
COLLECTION:
the collection the object came from (eg: Science Museum - Space Technology)

There are obviously a number of different types of data here: free text, identifiers, dates, places (which could be geocoded to geo coordinates), and dimensions. Additionally, COLLECTION and MAKER both come from a list of possible values.
