CSVW for energy datasets
This page collects examples of improving the FAIRness of datasets using the csv extension csvw. Most importantly, csv on the web offers a possibility to tie together metadata and data, starting from a well-known and widely used data format. The standard offers a rich framework to annotate existing csv documents with additional information and transform them into other forms of structured data exchange formats such as JSON(-ld) and RDF. At the same time, csv on the web is user-friendly offering a flexible mechanism from minimal FAIR extensions to elaborated context building for the data to be shared. CSV on the web is a W3C recommendation in coherence with ...
FAIR principles
The example illustrates how csv on the web contributes to realize the FAIR principles
To be Findable:
F1. (meta)data are assigned a globally unique and eternally persistent identifier.
F2. data are described with rich metadata.
F3. (meta)data are registered or indexed in a searchable resource.
F4. metadata specify the data identifier.
To be Accessible:
A1 (meta)data are retrievable by their identifier using a standardized communications protocol.
A1.1 the protocol is open, free, and universally implementable.
A1.2 the protocol allows for an authentication and authorization procedure, where necessary.
A2 metadata are accessible, even when the data are no longer available.
To be Interoperable:
I1. (meta)data use a formal, accessible, shared, and broadly applicable language for knowledge representation.
I2. (meta)data use vocabularies that follow FAIR principles.
I3. (meta)data include qualified references to other (meta)data.
To be Re-usable:
R1. (meta)data have a plurality of accurate and relevant attributes.
R1.1. (meta)data are released with a clear and accessible data usage license.
R1.2. (meta)data are associated with their provenance.
R1.3. (meta)data meet domain-relevant community standards.

The csv file contains information on the name of the initiatives, its legal status, its year of foundation, its national identifier, its street address, the city it is located in, the corresponding postal code, a possible C/O information, a latitude geo-information of the location (lat), a longitude geo-information of the location (lon), the website of the initiatives, some information for activities, a national industrial sector classification, a purpose statement in original language, the same purpose statement translated to English, the date of removal, the country code, and its legal form. To relate metadata information to this information in the csv file, we create a second file containing this metadata. The file format for this metadata information file is json. Let us assume that the csv file itself has the filename "SWE_initiatives_sample.csv". According to the csv on the web standard, the metadata file should have the filename "SWE_initiatives_sample.csv-metadata.json". A minimal form of the metadata file contains the following information
{
"@context": "http://www.w3.org/ns/csvw",
"url": "SWE_initiatives_sample.csv"
}
The @context information links to the language conventions of the csvw standard, the url information states the filename of the csv file. This minimal file can be extended to contain more specific metadata. All entries are encoded in the form of property specifications and corresponding values.
{
"@context": "http://www.w3.org/ns/csvw",
"url": "SWE_initiatives_sample.csv"
"dc:title": "Example - list of citizen-led initiatives in Sweden",
"dc:description": "List of citizen-led initiatives in Sweden, example dataset to be used for illustrating the use of csv on the web",
"dc:creator": {
"schema:name": "August Wierling",
"schema:url": "https://orcid.org/0000-0002-7443-7593",
"schema:contactPoint": { "email": "augustw@hvl.no}
}
As in the example above, property specifications can be terms from popular metadata vocabularies. E.g. the Dublin Core, schema.org, or DCAT vocabulary can be used. All of these vocabularies can be used independently or together. In the above example, metadata terms from the Dublin core vocabulary are mixed with terms from schema.org. The title of the csv file, and its description are stated using the Dublin core terms. The information inside of the dc:creator term contains information which in turn is specified using the schema.org vocabulary. Information about the creator is given in more detail specifying a human-readable name of the creator, a url of the creator (here: his orcid number), and contact point details such as the email. The contact point information can be extended using also a telephone or a fax number.
The date follows ISO 8601. The language is specified following RFC 4646. For the media type, RFC 7111 has being used as a specification. The type is taken according to the DCMI type vocabulary
