<div dir="ltr"><div>Hi Tom,</div><div><br></div><div>We are now implementing a catalog using the ISO 191939 profile to store raster metadata. </div><div>We store some metadata about the acquisition platform and sensor inside fields like supplementalInformation (MD_DataIdentification -> gmd:supplementalInformation), collectiveTitle (CI_Citation -> gmd:collectiveTitle) or alternateTitle (CI_Citation -> gmd:alternateTitle), and we need to query by these fields.</div><div><br></div><div>We are starting another project using the ISO 19139-2 standard to catalog products from a SAR satellite mission.

<br>
</span>Can you provide more context or use case(s)? Is the goal here solely<br>
to extend queryables against additional columns from a custom<br>
database? Do these queryables need to be provided in the CSW response<br>
(i.e. returnables)? Can you provide some examples of what sample<br>
queries could look like?<br>
<br>
We've had similar discussions before, and implementation/enhancement<br>
options range from allowing an extensible queryables approach via<br>
configuration, to custom non-standard CSW application profiles (which<br>
I'd tend to avoid unless absolutely required).<br>
<br>
Cheers<br>
