State

• Under Discussion
• In Progress
• Completed
• Rejected
• Deferred

Motivation

To expand GeoServer's styling capabilities and compatibility for the YSLD format.

Proposal

To move the community YSLD module to extension status.

The YSLD module has been a community module since at least 27/Apr/16 (GEOS-7520), following the transfer of the YSLD module into GeoTools. At this point, the module already satisfies many of the requirements for promotion:

• The module has at least a “handful” of users: The module has been the subject of multiple workshops, and judging by Jira and mailing list activity, the module is used by at least a "handful" of users.
• The module has a designated and active maintainer: Kevin Smith is currently the maintainer of the gs-ysld module.
• The module is considered “stable” by the majority of the PSC.
• The module maintains 40% test coverage: The package scores a 71% line coverage / 60% branch coverage with Cobertura. (An additional test for the getStyle method is forthcoming).
• The module has no IP violations.
• The module has a page in the user manual. The documentation was updated at foss4g 2016 and includes the module's installation, use, and a thorough YSLD reference. There is also a workbook section with more details and examples.
  • YSLD Styling Manual
  • YSLD Styling Workbook
• The maintainer (Kevin Smith) has signed the GeoServer Contributor Agreement.
