# Old photographs from Helsinki City Museum

This is an image dataset consisting of 5947 old photographs (until 1917) from the collections of the Helsinki City Museum, obtained from the Finna.fi discovery service.
The images are intended to be used for different AI/ML tasks such as generating captions or colorizing them.

The images themselves are JPEG files under the directory `images`.

The `metadata.jsonl` file contains metadata about each image, for example descriptive captions (mostly in Finnish), subject keywords, location and the name of the photographer.
The file is in JSON Lines format (each line is a JSON record). The `file_name` column contains the relative path of the JPEG image file.

The Python script `collect-hkm.py` was originally used to retrieve the metadata and images from the from Finna API.

The images have been published by the Helsinki City Museum in Finna using the Creative Commons Attribution 4.0 license and these attribution instructions:
