Support for generic attribute query parameters

[dirk-ecker]

It would be nice if all entities would support generic query parameters corresponding with their result attributes or at least for selected attributes.

Here in example for the features entity

http:///helgoland-adapters-webapp/api/features?properties.domainId=Wupper-Talsperre_Ablauf,Wupper-Talsperre_Absperrbauwerk

gives me

{
        id: '7',
        properties: {
          label: 'Wupper-Talsperre, Ablauf',
          href: 'http://agro060.icg.kfa-juelich.de:1113/helgoland-adapters-webapp/api/features/7',
          domainId: 'Wupper-Talsperre_Ablauf'
        },
        type: 'Feature',
        geometry: { type: 'Point', coordinates: [Array], crs: [Object] }
      },
      {
        id: '71',
        properties: {
          label: 'Wupper-Talsperre, Absperrbauwerk',
          href: 'http://agro060.icg.kfa-juelich.de:1113/helgoland-adapters-webapp/api/features/71',
          domainId: 'Wupper-Talsperre_Absperrbauwerk'
        },

or am I missing something and this is already possible?

Another good alternative would be https://graphql.org, that supports a rich query language.

Thanks in advance for your response.
