dataset 0.3.4027

• The new bibrecord() class is handles is the superclass of the dublincore and datacite() classes; these classes have a new print method and they are conforming the current library standard DCTERMS and current repository standard DataCite; unlike utils::bibentry(), they handle contributors and their roles, identifiers, and many other attributes.
• Breaking change: the definition metadata field in the defined() class is changed to the more understandable concept name.
• The defined() vectors print nicely, and the dataset_df() class is more readable, too.
• The missing examples are present, including examples on the use of the semantically richer orange_df example dataset.
• Many code quality improvements and new tests.

dataset 0.3.4023

• Changed iris_df to orange_df in all examples
• xsd_convert() handles difftime classes and edge cases
• Small errors fixed in examples
• Test coverage increased

dataset 0.3.4021

• Added support for generic vector methods: length(), head(), tail(), as.vector(), as.list(), and subsetting ([, [[).
• Implemented comparison methods (==, <, >, etc.) that operate on the underlying data while maintaining semantic integrity.
• Introduced custom print() and format() methods that summarise metadata (label, unit, definition) in a concise and human-readable manner.
• Improved the summary() method for defined vectors to display variable metadata and integrate seamlessly with base R statistics.
• Enhanced the c() method to validate compatibility across all semantic attributes (label, unit, definition, namespace) before concatenation.
• Extended vignette with richer examples and explanations of semantic validation, namespaces, and metadata access.
• compare_creators() internal function to add all creators to joined datasets.

This update significantly improves the usability and robustness of semantically enriched vectors in both interactive and programmatic workflows.

dataset 0.3.4

• New release on CRAN.

dataset 0.3.2

• New Requirement setting for further works.

dataset 0.3.0

• Released on CRAN.
• 0.3.1. Is a minor bug fix with units test on old R releases. It does not affect the functionality of the package.

dataset 0.2.9

• dataset_ttl_write(): write datasets to turtle format;
• with helper functions get_prefix(), get_resource_identifier(), xsd_convert(), and dataset_to_triples().

dataset 0.2.8

New vignettes on

• Richer Semantics for the Dataset’s Variables

• Richer Semantics for the Dataset’s Observations

• Richer Description of the Datasets’s Structure for Meaningful Reuse Opportunities

dataset 0.2.7

• Released on CRAN

The devel branch contains new code that is not is validated, but as a whole the package is not working consistently.

dataset 0.2.6

• All tests are passing, all examples are running.

dataset 0.2.5

• datacite() has a new interface and an as_datacite() retrieval version. See the Working with DataCite Metadata vignette.
• dublincore() has a new interface and an as_dublincore() version. See the Working with Dublin Core Metadata vignette.

dataset 0.2.4

All tests are passing but documentation is not rewritten yet.

dataset 0.2.3

new subject class for recording subjects

dataset 0.2.2

New s3 classes for DataCite and Dublin Core bibliographic entries.

dataset 0.2.1

A minor correction to avoid vignettes downloading data from the Eurostat data warehouse on CRAN. Small readability improvements in the vignette articles.

dataset 0.2.0

• New methods for the dataset() s3 class: print.dataset(), summary.dataset(), subset.dataset, [.dataset, as.data.frame().
• New vignette on how to use the dataspice package programmatically for publishing dataset documentation.
• Released on CRAN.

dataset 0.1.9

• Incorporating minor changes from the rOpenSci and CRAN peer-reviews.

dataset 0.1.7

• After reviewing CRAN submission comments, and correcting documentation issues, submitted to rOpenSci for review before re-submitting to CRAN.

dataset 0.1.6.0001

• Add dataset_local_id() and dataset_uri() to the dataset functions.

dataset 0.1.6.

• A release candidate on CRAN after small documentation improvements.

dataset 0.1.4.

Development version available on Zenodo.

• dataset_export() is implemented with filetype = ‘csv’.
• Replacement functions are added to simple properties identifier(), publisher(), publication_year(), language(), description(), datasource_get() and datasource_set() [to avoid confusion with the base R source() function], geolocation(), rights(), version().
• Functions to work with structured referential metadata: dataset_title(), subject(), subject_create().

dataset 0.1.3.

• Vignette articles started to develop and consult the development plan of the project. See From dataset To RDF, Export and Publish A dataset Object, Datasets with FAIR metadata, all comments are welcome.
• New functions: download_dataset(), datacite(), and the dataset() constructor.

dataset 0.1.2.

• The definition of the dataset() class, an improved data.frame (tibble, DT) R object with standardized structure and metadata.
• Adding and reading DublinCore metadata and DataCite mandatory and recommended FAIR metadata metadata.

dataset 0.1.0.

First development version release.

• Added the Motivation of the dataset package vignette article.
