Concept - Multi Channel

GREYImplementation tracked in MAGNOLIA-3895@jira. GREY

Rationale

• the same content should be delivered differently (different HTML, format, ...)
  • a channel can be: a device, location, medium
• content can be excluded or made exclusive to one channel

Detection

• AggregationState has a channel property (a string)
• the multi channel filter sets this value by using a ChannelResolver** the STKChannelResolver uses the configured channels (see configuration)
• default value is Channel.ALL
• a channel parameter can be passed to oversteer the mechanism

Device

• device detection filter only detects the device
  • setups DeviceCapability (set as a context attribute, use IoC to get the object)
• this information is used by the ChannelResolver invoked by the multi channel filter

Caching

• the channel is part of the cache key

Rendering

• the default RenderableVariationResolver uses the current channel name

Content Structure

• content can be marked for specific channels (multiple channels)
• in the STK we provide a tab used by all the page properties dialogs
  • channels are read from site.channels
  • the some tab can be used by components if needed
• the channels are stored in the multivalue property channels
• if no such channel property exists the content is available in all channels

Content Delivery

• urls to /website/* map to the physical workspace website
• /* maps to the virtual workspace magnolia
• the virtual workspace
  • uses the channel property of the aggregation state and the content to exclude/include content
  • mainly a content filter
• implemented by a filtering session wrapper
• the virtual workspace is registered on startup

Configuration

• the channels are configured in site/channelConfigurations (ordered map)
• each channel has a resolver (an interface)
• used by the global ChannelResolver
• first match wins

AdminCentral

• open /website/* url
• make it configurable

Alternative: request parameter

• pass the channel request parameter (ALL) to the url
• should we do that for the site name
• use the new named and pimped selectors
