Does this working group intend to publish anything (e.g. advice) on how to handle null values in CSV data? Perhaps as part of the metadata work, given that current usage varies. I would like to see some guidance covering: * 'the meaning of null' - i.e. recognition of the range of possibilities. OGC's gml:nilReasonType (http://www.opengeospatial.org/standards/gml) extends the idea of xsi:nil (http://www.w3.org/TR/xmlschema-1/#xsi_nil; http://www.w3.org/TR/2001/REC-xmlschema-0-20010502/#Nils) * Giving null values in columns of different data types * Any interaction with whether strings are quoted or not Thanks Yours Peter Peter Parslow Principal Geographic Information Architect Content & Data Products, Ordnance Survey Adanac Drive, SOUTHAMPTON, United Kingdom, SO16 0AS Linked data / map: http://data.ordnancesurvey.co.uk/id/postcodeunit/SO160AS Phone: +44 23 8005 5341 Mobile: +44 7796 610020 www.ordnancesurvey.co.uk | Peter.Parslow@ordnancesurvey.co.uk Please consider your environmental responsibility before printing this email.
