62. Research and
Development
Where GeoServer is heading
62

63. Time Boxed Release
• Predictable releases cycle
•Stable: monthly releases
• new features that do not change the API or
Stability
•Master
• 1-4: open for change proposals
• 5-6: release candidate and final release!
•s
63

64. Catalog Service
• A very simple Catalog Service
• Publish the GeoServer contents via CSW
• Allowing it be easily harvested
• (Not a full replacement for GeoNetwork)
• The Service is working
• Uses simple Dublin Core backed by text files
• API is defined, any one interested in working
on a database implementation
64

65. Sensor Observation Service
• Publish observations & measurements
(often as they are collected)
• Service is Currently under construction
• Currently sorting out XML bindings
• Sign up the the developer list to lend a
hand!
65

66. OSGeo Incubation
• We are done the checklist
• Code / Doc / Data Review to go
