lupa: Data Profiling and Quality Measurement
Profiles tabular data and measures its quality. Discovers structural patterns, implicit types, mixed date formats and reusable findings about potential data issues; defines quality frameworks with user-declared dimensions, reusable metrics with explicit granularity and typed aggregation; keeps versioned histories and detects structural drift; writes self-contained HyperText Markup Language reports; and produces editable cleaning plans that apply only the actions the user selects, with an audit log. The general model follows Batini and Scannapieco (2016) <doi:10.1007/978-3-319-24106-7>. The package implements version 1.6 of the data quality management framework for digital government of the Uruguayan Agency for Electronic Government and Information and Knowledge Society, AGESIC (2020) <https://www.gub.uy/agencia-gobierno-electronico-sociedad-informacion-conocimiento/comunicacion/publicaciones/marco-trabajo-para-gestion-calidad-datos>; an optional taxonomy of the fifteen characteristics of the standard 25012 of the International Organization for Standardization and the International Electrotechnical Commission, ISO/IEC (2008) <https://www.iso.org/standard/35736.html>; and the four levels and nineteen principles of the national quality assurance framework of the United Nations (2019) <https://unstats.un.org/unsd/methodology/dataquality/>, as adapted for Latin America and the Caribbean by the Statistical Conference of the Americas of the Economic Commission for Latin America and the Caribbean, CEA-CEPAL (2022) <https://repositorio.cepal.org/handle/11362/47464>. AGESIC, CEA and CEPAL are the Spanish acronyms of these institutions.
