Hi,
I am looking for a open source software to convert csv file to RDF based
on one pre-defined ontology. Also, this converter should support
complicated SQL queries (e.g., Group BY query and IF/THEN/ELSE query)
while defining the mapping between csv to our pre-defined ontology.
thanks
ying
Dear Ying,
maybe this could help[1].
all the best

Ying, this might sound like a stupid question, but if you want SQL
features why not pull your CSV into a relational DB table then R2RML it
into RDF (since mappings will allow you arbitrary SQL)?

Hi Ying,
We make a tool called Spyder, which is not open-source, but is free -
http://www.revelytix.com/content/spyder. It will let you use R2RML over a
CVS file directly to convert to RDF (or query with SPARQL without
converting).

Hey Ying,
why don't you just convert CSV to "raw" RDF and then do the mapping, using
SPARQL 1.1?
Google Refine with RDF extension should be enough to do the first step:

You can also pull your CSV into a spreadsheet and work with NOR2O [1]
Moreover, you can find a more complete list here [2]

As Davide points, any23 converts CSV to RDF in a rather concise and
useful way. (naive conversions will involve way too mnay triples
making it very inefficient)
best of luck.
you are 1 java call away from loading it into your favorite triple store.

Dear Ying,
Another option is

It is a kind of converter just like drag and drop way

Hi Ying,
Note Virtuoso can be use to map CSV files to SQL either by bulk loading if
there are many files as detailed at:
http://www.openlinksw.com/dataspace/dav/wiki/Main/VirtCsvFileBulkLoader
or via the Virtuoso Conductor from the “Database -> Import” tab if you only
have a single or
Moreover, this in line with our paper Data Shapes and data
transformations [1] [2]

Also in ths category you can use Datalift to do naive CSV to RDF and
then SPARQL CONSTRUCT. Also provide a simple GUI to generate part of the
CONSTRUCT queries.

Hi Ying,
I'd like to add to the list these two softwares:
* Karma: http://www.isi.edu/integration/karma/
* VIVO Harvester: http://vivo-project.github.com/
They both can import data from either CSV files or relational data bases.
We used them to convert some data to RDF expressed using the VIVO on
