NAME


csv2rdf - converts CSV to RDF

SYNOPSIS


csv2rdf -b <instance-base> -p <property-base> [-c <classname>] [-i <identity column(s)>]
[-l <label columns>] [-s <N>] [-o <output>] [-f configfile] [--col<N> <colspec>]
[--prop<N> <property>] <[-d <delim>] [-C] [files...]

DESCRIPTION


Reads csv files from stdin or given files

if -d is given, use this delimiter

if -s is given, skips N lines at the start

Creates a URI from the columns given to -i, or automatically by numbering if none is given

Outputs RDFS labels from the columns given to -l

if -c is given adds a type triple with the given classname

if -C is given, the class is defined as rdfs:Class

Outputs one RDF triple per column in each row.

Output is in n3 format.

Output is stdout, unless -o is specified

Long options also supported: --base, --propbase, --ident, --class, --label, --out,
--defineclass

Long options --col0, --col1, ... can be used to specify conversion for columns.

Conversions can be:

float(), int(), split(sep, [more]), uri(base, [class]), date(format)

Long options --prop0, --prop1, ... can be used to use specific properties, rather than
ones auto-generated from the headers

-f says to read config from a .ini/config file - the file must contain one section called
csv2rdf, with keys like the long options, i.e.:

[csv2rdf]
out=output.n3
base=http://example.org/
col0=split(";")
col1=split(";", uri("http://example.org/things/",
"http://xmlns.com/foaf/0.1/Person"))
col2=float()
col3=int()
col4=date("%Y-%b-%d %H:%M:%S")

Use csv2rdf online using onworks.net services
