Description

According to https://github.com/openml/openml-r/issues/316 people want this.
@ja-thomas requested this again.
This is the usecase:
People have a list of data.ids (or task.ids) and often want to list the data/task properties (e.g. number of instances, ...). Is there an API where we can get this information?

Something like
https://www.openml.org/api/v1/json/data/list/1,2,3 which should give you the results of data with id 1,2 and 3. Similar to the API call https://www.openml.org/api/v1/json/evaluation/list/run/1,2,3

Research direction

Start by comparing the existing /api/v1/json/evaluation/list/run/1,2,3 endpoint with the requested data/list and task/list entry points. Determine how comma-separated IDs should return the corresponding dataset or task properties, and consider the earlier openml-r issue and linked use case when defining done.
