Define URL parameters approach

[fdalcin]

As a developer I'd like to define a final standardized way to use/apply filters on the catalog.

Right now each filter uses its own way to be rendered and queried, e.g.:

• Licenses display the name and use a "slugged" version when applying the filter so the URL looks like this licenses[]=all-rights-reserved&licenses[]=cc-by
• Subjects display the name and use the Thema code when applying the filter so the URL looks like this subjects[]=JNR&subjects[]=L
• Institutions display the name and use the actual name when applying the filter so the URL looks like this institutions[]=Ontario+Tech+University&institutions[]=Université+de+l’Ontario+français
• Publishers display the name and use the actual name when applying the filter so the URL looks like this publishers[]=Press+Books

Definition of done

We have defined and implemented a standardized way to apply filters using either a slug, id/code, or the actual name.
