Which file formats can be previewed on CKAN Data P

问题:

I am working on CKAN and will like to know the appropriate file formats that can be previewed on CKAN. I could not find any information on this topic online, so I decided to start this topic and hope to garner more responses on this which will be useful to CKAN developers in future. Here's a list of file formats that I have gathered after experimenting with my own CKAN and looking through other CKAN instances such as those from UK and Australia.

Can be previewed:

• CSV (Comma separated values)
• XLS (Microsoft Excel Binary File Format)
• HTML (HyperText Markup Language)
• JSON (JavaScript Object Notation)
• PDF (Portable Document Format)
• RSS (Really Simple Syndication)
• TXT (Plain Text)
• WMS (Web Map Service)
• XML (eXtensible Markup Language)

Cannot be previewed:

• DOC (Microsoft Word)
• RDF (Resource Description Framework)
• HTML (HyperText Markup Language)
• KML (Keyhole Markup Language)
• SHP (Shapefile)
• WFS (Web Feature Service)
• XLSX (Microsoft Excel Open XML Document)
• ZIP (archive)

Help add on to my list and correct me if any of the above is wrong, then I will update the list above. Thanks! ;)

For each ckan release, the data viewer's functionality may differ.

Refer to the DataViewer section in the documents of the CKAN version that you are using.

With some simple tweaks to the config file XLSX files can be previewed, as can Tab separated text files (tsv format/extension).

Edit the config.ini file to include

ckan.datapusher.formats = csv xls xlsx tsv application/csv application/vnd.ms-excel application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

HTML and RDF are also previwable: refer CKAN documentation http://docs.ckan.org/en/latest/maintaining/configuration.html?highlight=preview#ckan-preview-loadable
