Colour - Datasets ================= Colour science datasets for use with `Colour `__ or any Python package manipulating colours. The datasets are hosted in `Zenodo `__ under the `Colour Science - Datasets `__ community. It is open source and freely available under the `BSD-3-Clause `__ terms. .. sectnum:: Features -------- **Colour - Datasets** was created to overcome issues encountered frequently when trying to access or use colour science datasets: - No straightforward ingestion path for dataset content. - No simple loading mechanism for dataset content. - Unavailability of the dataset, e.g. download url is down, dataset content is passed directly from hand to hand. - No information regarding the definitive origination of the dataset. **Colour - Datasets** offers all the above: it allows users to ingest and load colour science datasets with a single function call. The datasets information is hosted on `Zenodo `__ where the record for a dataset typically contain: - An *urls.txt* file describing the urls to source the dataset files from. - A copy of those files in the eventuality where the source files are not available or the content has changed without notice. - Information about the authors, content and licensing. When no explicit licensing information is available, the dataset adopts the **Other (Not Open)** licensing scheme, implying that assessing usage conditions is at the sole discretion of the users. Examples ^^^^^^^^ **Colour - Datasets** can also be used online with `Google Colab `__. Most of the objects are available from the ``colour_datasets`` namespace: .. code-block:: python import colour_datasets The available datasets are listed with the ``colour_datasets.datasets()`` definition: .. code-block:: python print(colour_datasets.datasets()) .. code-block:: text colour-science-datasets ======================= Datasets : 22 Synced : 1 URL : https://zenodo.org/communities/colour-science-datasets/ Datasets -------- [ ] 3269926 : Agfa IT8.7/2 Set - Marszalec (n.d.)
