Thanks Godfrey,
It really is a lot of information!
I tried downloading exiftool yesterday, but that was not successful, I
will try again later. Indeed Iam using windows10

Jos,
Thanks for sending the file. It downloaded with no problems.
EXIFtool v10.05 has no problem reading all the metadata. I ran it from a
Terminal window on macOS with the default command after moving to the directory:
$ cd ~/Downloads
$ exiftool 20160528-IMGP0169.DNG > EXIFdata.txt
and it spit out the (rather lengthy) metadata very nicely. For example:

Of course, that's a bit of a lot to read through and it's only a tiny fraction
of what's in there. The thing to do is to modify the EXIFtool command to read
out just the bits of info that you're interested in. EXIFtool reads 226 EXIF
keys in the .DNG file … you cut it down by using the short names of the keys in
the command. For example:
$ exiftool \
-FileName \
-FileModifyDate \
-FileAccessDate \
-FileInodeChangeDate \
-Make \
-Model \
-Copyright \
-ExposureTime \
-FNumber \
-ExposureProgram \
-SensitivityType \
-DateTimeOriginal \
-CreateDate \
-Flash \
-FocalLength \
20160528-IMGP0169.DNG > EXIFdata3.txt
outputs the following into EXIFdata3.txt:

If you run exiftool from the command-line with no parameters, it will enter its
help mode and you can read all about using it along with examples. Phil Harvey
is also very good about responding to queries if something isn't clear.
I imagine that on a Windows system, you'd use the Windows command-line
interface to run it … Someone more familiar with Windows systems will have to
speak to that.
Go for it! :-)

Why not just use EXIFtool? If someone wants to make a raw file available, I'd
like to do some testing.

Does PhotoME still rely on Exiftool for extraction of data?
If so, you may have to wait until that library has been updated.

<jos_from_holl...@4prof.nl>:
Maybe more than a decennium I use PhotoMe to read metadata from Pentax
image files, now, with K1, this has come to an end.
When reading metadata from DNG files from my K5 (with PhotoMe), I can
see the the manufacturer notes that inform a.o. the shutter count and
the lens identification codes.
Reading a K1 file, the manufacturer notes are missing and I get an
error
message from PhotoMe.
Both cases I read directly from the same SD card.
LR6 seems to have no problem in reading the notes, because the correct
lens name is displayed.........
Is an easy metadata reader like PhotoMe known, that could handle K1
files??
Greetz, Jos
------->error message from PhotoMe:
2 problems were found in the metadata of this file.
1. Image tag DNG Private Data refers to Maker Notes in an
unknown format
The Maker Notes format is not supported by PhotoME.
2. Too many items (17744) in IFD MakerNote (Manufacturer notes)
The number of tags in the Maker Notes IFD is very high. PhotoME has
identified this as a problem and has ignored this IFD in the
initialization process.
Possible reasons:
• PhotoME could not correctly determinate the base address of the Maker
Notes
• The metadata may have been damaged by other software
