CoMeta Ontology

Dataset content providing annotations that were produced or obtained from raw data content, or alternatively, from a data descriptor.

• annotates data ^op
• has content type ^op

Dataset content that describes the raw data content via features or encodings extracted from the former. This should not be confused with an annotation, but as a supplementary view of the raw data content of a dataset.

• describes data ^op
• has feature type ^op

Describes the type of content that the raw data, or its annotaitons, provide. In the music domain, this may correspond to chord, pattern, emotion, etc.

Dataset content providing raw data of structured (e.g. tabular data) or unstructured (e.g. audio files). For example, a dataset folder containing images can be described as raw data content.

• has content type ^op
• has modality ^op

• annotates data ^op
• describes data ^op

Describes an Application Program Interface (API) for accessing, recreating, or extracting a dataset.

Describes the availability of data content according to the release strategy and policies of the dataset. For example, a music dataset may provide complete data records (full tracks) or contain audio clips or snippets (excertps) only.

Describes the accessibility of a dataset, instructing users on the modalities put in the place by the maintaners to access its content.

Describes the available of a dataset as a whole, or of a part of its content.

• has API ^op
• has accessibility ^op
• mm:hasLicense
• download link ^dp

The format of the data in which content is provided.

Describes the modality of dataset content such as audio, video, image, etc.

A container of data records with summative properties that allow the contextualisation of its content, availability and licensing.

• extends ^op
• has availability ^op
• has content ^op
• has split ^op
• has subset ^op
• is aimed for ^op
• is maintained by ^op
• contains record ^op
• mm:hasGenre
• record count ^dp

• extends ^op
• has split ^op
• has subset ^op

Describe the content of a dataset from a summative perspective (e.g. the audio content of a music collection, the audio features it provides, etc.) and its production process (provenance).

• has availability ^op
• record count ^dp

• Content Annotation ^c
• Content Descriptor ^c
• Raw Data Content ^c

A record of a dataset, providing references to its properties and annotations.

• has assignment ^op
• contains record ^op

Describes a partition of a dataset via its association with individual data record, which can be used for training, validating, or testing a computational method.

Describes the type of feature provided by a content descriptor.

A production method is an activity that generates one or more artefacts that joinlty characterises data content.

The type of a split that associates a function to the corresponding data partitions (e.g. a training set).

Associates an annotation to the raw data, or data descriptor, it annotates

• Content Descriptor ^c
• Raw Data Content ^c

Associates a data descriptor (e.g. features, encodings) to the raw data they were derived from

Associates an API to the availability information of a dataset

Associates the availability of a dataset to the way it can be accessed

Associates a dataset split to a dataset record

Associates a dataset to information related to its availability and access

• Dataset ^c
• Dataset Content ^c

Associates a dataset to its content

Associates raw data content or annotations to their type (e.g. tag, pattern, emotion).

• Content Annotation ^c
• Raw Data Content ^c

Associates a data descriptor to the type of feature it provides

Associates raw data content to the modality the data provides

Associates a dataset to a proper partition (a particular subset) of it

A dataset can be a subset of another dataset

Associates a dataset record to an atomic music element

• mm:MusicEntity
• mm:Recording
• mm:Release
• mm:Score
• mm:Text

Associates a dataset to a task it enables

Associates a dataset to one of its maintainers (e.g. a person, an institution)

Associates a dataset record to the dataset it belongs to.

A textual description
