• simplify get_concept(). Search parameters are now not provided via a table anymore, but as a combination of column name and value to search for in that column. They can also be provided as a string that represents a query that would be used in dplyr::filter(), where several search conditions can be combined arbitrarily.
  • also allow building trees of the parents, not only the children in make_tree()
  • fix acknowledgement and adapt to update of dplyr
  • implement better filtering on parent concepts to simplify editing matches.
  • include matches with 0 difference already as close match, for convenience.
  • when matching a new dataseries with old concepts, give a message and ignore non-close matches.
  • fuzzy matching implemented. When concepts that are new for mapping do not match exactly, fuzzy matching is carried out and three new columns are offered for assigning the new concepts to harmonised concepts
  • small fix that would not allow to match with an empty set of values.
  • introduce function where a table with columns per classes in the ontology can be used to retrieve concepts. This table is matched with a flattened ontology. Currently, no mappings are attached to this table.
  • reconstruct regex functionality and enable extracting of external concepts in get_concept()
  • describe an ontology either by version, or by date
  • revision of vignettes
  • include functions export_as_rdf() for being able to explort any ontology in other, semantic-web based, formats.
  • various fixes of convenience and to make ontologics work smoothly together with arealDB
  • allow it that also classes are handled with the new_mapping() function, which also means that new_class() can now only set harmonised classes.
  • adapt the onto-class structure according to issue https://github.com/luckinet/ontologics/issues/6; this entails that concepts and classes are summarised into their respective slot, with sub-tables “harmonised” and “external”, featuring specific columns.
  • change all functions to support this new structure
  • this changes the behaviour of the function new_concept() insofar that this only creates harmonised concepts (so no source needs to be provided here anymore) and of the function new_mapping() insofar that this now creates external concepts and their mapping to harmonised concepts (and thus writes into the sub-table “external” and into the “mapping-columns” of the sub-table “harmonised”)
  • adapt new_concept() so that also concepts can be defined that have no class (for various reasons). This now gives a warning, and inserts the concepts with an “undefined” class.
  • revise all functions that access an ontology to work either in the .GlobalEnv, or at the given path. The argument path = was therefore changed to ontology =.
  • Instead of taking merely the terms, functions new_concept() and new_mapping() now take the output of get_concept() of already existing concepts, or at least a table with columns ‘code’, ‘label_en’ and ‘class’.
