Purpose of field “Format” for links

[effjot]

What is the intended use of the “Format” field for links? File formats should already be covered by the quite extensive MIME Types list. Thanks for the clarification!

IIRC, we used what was done in QGIS, if you open your metadata tab, then "Links" tab. It's defined in the internal QGIS XSD for storing metadata.

We still want to integrate as much as possible with the QGIS Metadata native panel #24

Thanks!

For further reference, the QGIS link fields are described in qgis-base-metadata.xsd, starting at line 188:

• name: short name (like WMS layer name)
• type: link type. Strongly suggested to use values from the 'identifier' column in https://github.com/OSGeo/Cat-Interop/blob/master/LinkPropertyLookupTable.csv
• description: abstract text about link
• url: endpoint. If the URL is an OWS server, specify the base URL only without parameters like service=xxx.....
• format: format specification of online resource. Strongly suggested to use GDAL/OGR format values
• mimeType: MIME type representative of the online resource response (image/png, application/json, etc.)
• size: estimated size (in bytes) of the online resource response

I’m not quite sure what the “GDAL/OGR format values” are. In many examples I’ve found in code and on the Web, Format stayed empty. I have seen one example where it was “ESRI Shapefile”, so my best guess is the GDAL format “Long name”.
