It consists of two datasets

    nc (License: CC BY-NC 4.0 International)
    cc0 (License: CC0 1.0)

The cc0 dataset is a strict subset of nc. It lacks the tag , which gives detailed information about the rooms (services) in accommodations. Unfortunately there is not much documentation about the data except a little in the .xsd file. The datasets are generated by https://github.com/ltog/tomas-gr/blob/master/release/create_release.py . I can trigger this creation any time. (It might be a good idea to do this shortly before the hackathon, so people will get fresh room availability data.)
