 The aim of the _dataset_ package is to make tidy datasets easier to release, exchange and reuse. It organizes and formats data frame R objects into well-referenced, well-described, interoperable datasets into release and reuse ready form.
 
-1. Offer a way to better utilise the `utils:bibentry` bibliographic entry objects by extending them with the fields of the Dublin Core and DataCite tenders, and making them detachable from the data. This extension aims to work with a [data.frame](https://www.rdocumentation.org/packages/base/versions/3.6.2/topics/data.frame) or an inherited [tibble](https://tibble.tidyverse.org/reference/tibble.html), [tsibble](https://tsibble.tidyverts.org/) or [data.table](https://rdatatable.gitlab.io/data.table/). See for more information the [Bibentry for FAIR datasets](https://dataset.dataobservatory.eu/articles/bibentry.html) vignette.
-2. Extending the `haven_labelled` class of the `tidyverse` for consistently labelled categorical variables with linked (standard) definitions and units of measures in our [defined](https://dataset.dataobservatory.eu/articles/defined.html) class.
-3. Offering a new data frame format, `dataset_df` that extends tibbles with semantically rich metadata, ready to be shared on open data exchange platforms and in data repositories. This s3 class is aimed at developers and we are working on several packages that provide interoperability with SDMX statistical data exchange platforms, Wikidata, or the EU Open Data portal.

 &#10;The primary aim of dataset is create well-referenced, well-described, interoperable datasets from data.frames, tibbles or data.tables that translate well into the W3C DataSet definition within the [Data Cube Vocabulary](https://www.w3.org/TR/vocab-data-cube/) in a reproducible manner. The data cube model in itself is is originated in the _Statistical Data and Metadata eXchange_, and it is almost fully harmonized with the Resource Description Framework (RDF), the standard model for data interchange on the web^[RDF Data Cube Vocabulary, W3C Recommendation 16 January 2014  <https://www.w3.org/TR/vocab-data-cube/>, Introduction to SDMX data modeling <https://www.unescap.org/sites/default/files/Session_4_SDMX_Data_Modeling_%20Intro_UNSD_WS_National_SDG_10-13Sep2019.pdf>].
