# csv2rdf(1)

converts CSV to RDF

## 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")
