WGD: indicate printed/electronic

[ErwinKomen]

See issue #44.

Show for each entry whether it occurs in the printed edition or only electronically.
The field opname (or in the current Excels: in woordenboek (ja/nee)) is a boolean (in the Excel files) that indicates whether the lemma has been taken up in a printed edition or not.

Notes

Note that this is already processed in the database and accessable internally. Each Entry has a boolean field inwoordenboek that indicates whether that entry is in the (written, published) dictionary or not.

The verdict per lemma differs:

verdict	number of lemma's
All entries of lemma in printed dictionary	1116
None of the lemma entries printed	2163
Mixed: some are printed, some not	637

Question

How and on what level should it be indicated that an entry (or a whole lemma) is available in the printed edition?

Answer

April 13th we decided: indicate this on the level of the entry, and do it by making the digital only items green
