read_package() now returns a warning rather than an
error when a datapackage.json contains no resources. This
allows use to create the JSON and then add resources with frictionless
(#265).example_package() now has a version
parameter, allowing to load the example Data Package following the Data
Package v1 or v2 specification (#249).add_resource() now allows to replace an existing
resource (#227).read_resource() now returns an error if both
path and data are provided (#143).write_package() no longer writes to "." by
default, since this is not allowed by CRAN policies. The user needs to
explicitly define a directory (#205).null values in a read datapackage.json are
now retained by write_package(), rather than being changed
to empty lists. Properties assigned by the user to NA and
NULL remain being written as null and removed
respectively (#203).vignette("data-package"),
vignette("data-resource"),
vignette("table-dialect") and
vignette("table-schema") describe how frictionless
implements the Data Package standard. The (verbose) function
documentation of read_resource() and
create_schema() has been moved to these vignettes,
improving readability and maintenance (#208, #246).example_package is removed in
favour of the function example_package(). This function
allows to reproducibly provide a local Data Package, without the need
for an internet connection. The observations resource was
also changed from a remote to a local resource and from CSV to TSV.
This change affects the use of example_package in
older versions of frictionless. We recommend to update
frictionless to the latest version (#114, #253).read_resource() is now more modular under the hood,
which should make it easier to extend (#210).CITATION.cff for citation and
Zenodo deposit (#206).print() prints a human-readable summary of
the Data Package, rather than a (long) list (#155).read_package() no longer returns a message regarding
rights and credit (#121). If package$id is a URL (e.g. a
DOI) it will be mentioned in print().add_resource() accepts additional arguments via
.... These are added as (custom) properties to the resource
and are retained in write_package() (#195).read_resource() now supports column selection via the
col_select argument from readr::read_delim().
This can vastly improve reading speed (#123). Tidy
selection is not supported.write_package() no longer adds
"profile": "tabular-data-package" to
datapackage.json. It is also removed from the example
dataset (#188).readr::problems() is included in NAMESPACE so you don’t
have to load readr to inspect parsing issues. The function is mentioned
in the documentation of read_resource() (#129).package) now has a
datapackage class (#184). This enables a custom
print() function (see above). check_package()
will warn if the class is missing, so previously saved Data
Package objects (without the class) will generate a
warning.check_package() is now a public function, so it can be
used in your package (#185). This and the other check_
functions return the first argument silently (rather than
TRUE), so they can be chained.create_package() now accepts a descriptor
argument so that a Data Package object can be created from an existing
object (#184). It will always validate the created object with
check_package().cli::cli_abort(), cli::cli_warn() and
cli::cli_inform() are used for all errors, warnings, and
messages (#163). This has several advantages:
frictionless_error_fields_without_name, making it
easier to test for specific errors.assertthat::assert() calls are now
if () statements..zenodo.json can be created with
checklist::update_citation().Suggests. It was removed as a dependency from rmarkdown 2.26,
resulting in “stringi package required for encoding operations” build
errors on CRAN (#176).skip_if_offline() to selected tests and verbosely
include output in vignette examples, to avoid CRAN errors caused by
timeouts (#116).datapackage.json, resource files, schemas) can
now be read from (s)ftp:// URLs (#102).add_resource() now sets format,
mediatype and encoding for added CSV file(s)
(#78).add_resource() now supports adding schema
via path or URL.write_package() now supports added data to be gzip
compressed before being written to disk (#98).read_resource() will now warn rather than error on
unknown encoding (#86).package objects no longer have or require the custom
attribute resource_names, use new function
resources() instead (#97).package objects no longer have or require the custom
attribute datapackage, making it easier to edit them as
lists (with e.g. append()).add_resource() now supports adding CSV file(s) directly
as a resource. This skips reading/handling by R and gives users control
over path (#74).example_package) are now downloaded when writing with
write_package(), rather than being skipped. This is more
consistent with locally read packages. The behaviour for resources with
a path containing URLs (only) and resources with
data remains the same (no files are written). The write
behaviour is better explained in the documentation (#77).write_package() now silently returns the output rather
than input package.create_package() will set
"profile" = "tabular-data-package" since packages created
by frictionless meet those requirements (#81).create_schema() interprets empty columns as
string not boolean (#79).read_package() can now read from a
datapackage.yaml file.read_resource() now accepts YAML Table Schemas and CSV
dialects.add_resource()/create_schema()’s
df argument is renamed to data.example_package’s observations resource
now has URLs as path to serve as an example for that.
