Dutch Claypipe - marks and finds database

The information from the book 'Goudse pijpenmakers en hun merken' has been placed into a relational database with records for the marks, owners and ownership. Also the information has been converted and split in order to get more meaningfull records.

The result is that we can now show the periods of mark ownership with a timeline and also we can get a list of an owners marks. Another important functionality is that for a mark you can view the finds that have been identified to be of the mark. This 'linking' between Mark and Finds is a great help when trying to identify a 'badly' readable mark on a find.

	Marks A mark's names and ownership periods.
	Owners A person or company and all marks owned.
	Finds Heelmark images of finds of a mark.
