Now let& #39;s see: 1st there is a documentation as docx (thanks), then a folder of sql tables (interesting) and one with zipped csv files. Let& #39;s pick objects.csv and see what& #39;s inside...

Ah, there are 28 columns (properties) with 135,715 rows (objects). Great!
Creation date is split in begin and end date, the oldest -490, i.e. b.c. Median: 1933, Mean: 1868.
"accessioned" is always "1".

"attribution" is the artist& #39;s name, "attributioninverted" the same with last name first.
Here is a histogram of all objects. The usual 500 years with a focus on the last 200.
Let& #39;s take a look what objects there are...

All right: 69.194 prints, 17.743 drawings and 17.325 photographs. Now it& #39;s getting exciting.
And 18.254 in "Index of American Design" which comprises watercolor renderings of American folk and decorative arts objects from the colonial period through 1900.
I see...

We also have subclassifications, but most of them are empty, some "drawings", 2.967 Contact Sheets etc.
We also have eleven abbreviated departments. Does anybody know, what "CG-W" stands for?

Now, you would like to see images, right? They are not in objects.csv.
But in published_images.zip
Here it is: 101,297 entries with twelve columns. An ID, a link to a thumbnail (hooray!) and a link to a #IIIF #JSON file!!!
For example: https://api.nga.gov/iiif/00004dec-8300-4487-8d89-562d0126b6a1__640/info.json

Now I can imagine doing a lot with this. But let& #39;s look at the thumbnails first.
Here are the first 1.000. How beautiful!

Now, how can I map the uuid from published_images to the objectid from objects? In published_images I find depictstmsobjectid. Bingo.
Object ID 17387 corresponds to UUID 00007f61-4922-417b-8f27-893ea328206c.

If you inspect the URL above, you find the thumbnail& #39;s dimensions: "/!200,200/". Ha! Could we modify it to get a hi res image?
Oh my! It renders to any resolution if you change the numbers.

If we have that, I am interested only in the classification "Photograph".
OK, here are the first 100 photos.

There is much more to discover. The csv files are cross referenced, objects can be part of a series or show watermarks, the "constituents" link to a Getty ULAN ID, "location" represents the object& #39;s whereabouts on @ngadc campus, etc.

This thread can only give a first impression and create curiosity. It is a community challenge to analyze the data and bring the artworks into new contexts online. That means: cultural heritage can be transformed into digital culture.
Go.
Thanks, @medievalben, @ngadc.
