Options¶
wdmapper can be controlled by several parameters. Run the command line client
with option --help
to get a full list of command line arguments.
Input and output¶
Option input (--input
or -i
) and option output (--output
or
-o
) can be used to select an input or output file. The special value
-
is used as default to denote the standard input or standard output,
respectively. Input is always assumed to be Unicode in UTF-8 encoding.
Option from (--from
or -f
) and option to (--to
or -t
)
can be used to select input or output format. Default input format is
csv
and default output format is beacon
. If no input/output format has
been specified, it is guessed from input/output filename extension, for
instance .csv
for CSV format and .txt
for BEACON format.
Examples¶
$ wdmapper convert -i mappings.csv -o mappings.txt
$ wdmapper convert < mappings.csv -t beacon > mappings.txt
Mapping retrieval¶
limit¶
Limit maximum number of mappings to process.
sort¶
Sort mappings (alphabetically) for stable output. This can slow down the query
so only use if needed. set to False
by default.
language¶
Specify language of labels. English (“en”) is used by default.
type¶
Filter Wikidata items to instances of some class or its subclasses. For instance the value Q5 (human) will only include mappings with Wikidata items about humans. Keep in mind that not all Wikidata items have proper instance statements and the class hierarchy often contains errors and unexpected subclasses! See wdtaxonomy for another command line tool to examine the Wikidata class hierarchy.
This option is ignored for command “check”!
cache¶
Disable caching. Set to False
by default.
sparql¶
Wikidata SPARQL endpoint, set to http://query.wikidata.org/sparql
by
default.
