NAME
picadata - parse and validate PICA+ data
SYNOPSIS
picadata [<command>] {path} {options} {files}
DESCRIPTION
Convert, analyze and validate PICA+ data from the command line.
COMMANDS
convert
Convert between PICA+ serialization formats (the default command).
split
Split records into multiple records for each level. Implies -o.
count
Count number of records, holdings, items, and fields.
fields/subfields/sf
List distinct fields or subfields in the data. Provide an Avram schema (-s/--schema) to include documenation.
explain
Lookup (sub)fields in an Avram schema given by option or from stdin. Optional (o/*), mandatory (./+), repeatable (+/*).
validate
Validate data against an Avram schema (-s/--schema).
build
Build an Avram schema from input data, optionally based on an existing schema (-s/--schema). Add option -B/--abbrev to abbreviate.
OPTIONS
--from, -f
PICA serialization type (plain, plus, binary, XML, ppxml) with Plain as default. Guessed from first input filename unless specified. See format documentation at http://format.gbv.de/pica.
--to, -t
PICA serialization type to enable writing parsed PICA data.
--number, -n
Stop parsing after n records. Can be abbreviated as -1, -2...
--order, -o
Sort record fields by field identifier and by occurrence at level 2.
--annotate, -a, -A
Enforce annotated PICA as output format or prevent with -A. Combined with --schema this will set annotations ! and ? to mark validation errors.
--path, -p
Select fields or subfield values specified by PICA Path expressions. Multiple expressions can be separated by | or by repeating the option. Positions such as /3-7 are read as occurrence ranges.
--schema, -s
Avram Schema to validate against. Can be a file or an URL.
--unknown, -u
Report unknown fields and subfields on validation (disabled by default).
--abbrev, -B
Abbreviate the Avram schema (with command <build>).
--color, -C
Colorize output. Only supported for PICA plain and PICA plus format.
--mono, -M
Monochrome (don't colorize output).
--version, -V
Print version number and exit.
EXAMPLES
picadata pica.dat -t xml # convert binary to XML
picadata count -f plain < pica.plain # parse and count records
picadata 003@ pica.xml # extract field 003@
picadata validate pica.xml -s schema.json # validate against Avram schema
# document fields used in a record
picadata fields pica.xml -s https://format.k10plus.de/avram.pl?profile=k10plusSEE ALSO
