Overview
This RFC proposes extending the MapDefinition to allow the default server options to be overriden per map.
Motivation
Many of the options for a Map are currently only configurable via serverconfig.ini, which prevents customising and performance tuning.
Proposed Solution
Add the support for the following options to the MapDefinition Schema
- image format (per map and base layer group)
- jpeg compression factor
- palette quantize algorithms
- meta tiling factor (per map and base layer group)
- selection color
- tile cache expiry headers
Rather than hardwire these elements into the schema, it is proposed to
introduce an options schema element, to facilitate future enhancements
without requiring the map definition schema to be revised.
Implications
A new MapDefinition schema will need to be created and client tools & viewers updated to support it
