Datasets/Data Resources Sample Clauses

Datasets/Data Resources. The representation of RDF graphs that are created from the input data delivered by the data providers. A data resource is an RDF graph that is provided on the Web. Typically, it represents a subgraph of a dataset. Each level is a meta-level of the former level. CHOs are the real world objects, aggregations represent the metadata of CHOs from the providers’ perspective, the datasets and data resources represent actual RDF representations from DM2E’s perspective. CHOs and Aggregations are taken from EDM and partly specialised (see Section 4). The datasets are described using the VoID vocabulary, the data resources are used to connect VoID and OAI-ORE, based on Linked Data principles. 8 Europeana libraries website: ▇▇▇▇://▇▇▇.▇▇▇▇▇▇▇▇▇-▇▇▇▇▇▇▇▇▇.▇▇/web/ [20.01.2015]. 9 Europeana creative website: ▇▇▇▇://▇▇▇.▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇.▇▇/ [20.01.2015]. 2.1 Datasets‌ Datasets are identified by an URI and belong to the class void:DataSet. A void:Dataset is a set of RDF triples that are created from the data of a single data provider. The content of a dataset in DM2E is stable. Typically, a dataset is created from the transformation of one or more files of the data provider. A new transformation of the same files results in a new dataset. When dereferenced, a description of the dataset is provided, including provenance information and links to different versions.‌ 2.2 Data Resources
