State of GeoServer provides an update on our community and reviews the new and noteworthy features for 2018. GeoServer is a web service for publishing your geospatial data. using industry standards for vector, raster and mapping.

We have an active community and a lot to cover for 2.12 and 2.13 release, as well what is cooking in September’s 2.14 release.

Each release provides exciting new features, this talk covers diverse improvements across GeoServer:
* OGC compliance work for WFS 2.0 and WMTS 1.0, WFS 3.0 support
* improvements for cloud deployments
* cascade WMTS services
* progress in NetCDF support
* getting ready for the Java 18.9 roadmap
* And much more…

Attend this talk for a cheerful update on what is happening with this popular OSGeo project. Whether you are an expert user, a developer, or simply curious what GeoServer can do for you.

  51. 51. Isolated Workspaces Workspaces are used to partition what is published for ease of management: ● A workspace has a namespace (used to keep XML content from conflict) ● Workspace published as a web service Problem: ● INSPIRE standard requires the use of a specific namespace ● Cannot use same namespace, preventing reuse of INSPIRE namespace Isolated workspace: ● Allows one workspace to publish the common layers ● The remaining workspace (each one marked isolated) can reuse these common layer Allows the same application schema to be published from multiple workspaces, each mapped onto different datasets 2.13.0 Nuno Oliveira GeoSolutions SYKE
  52. 52. JDBCConfig and JDBCStore (Community) Use a database, rather than data directory, for clustering: ● GeoServer “Catalog” configuration ● GeoServer support files (styles, icons, fonts, config files) Work done for 2.13: ● Reduce number of database queries to improve performance ● Consistently log configuration queries for analysis 2.13.0 Niels Charlier Steve Ikeoka -

  55. 55. Help us help you
  56. 56. User List Participation ● Answering users questions relies on a low number of people Action: ● We are sending reminder on effective use of the user list on subscription and at the bottom of each mail ● Community building activity - remind developers about the definition of “supported” (not only reviewing pull requests, also answering user questions, used to be obvious, but it’s not obvious to devs hired into open source)
  57. 57. ● Keep exploit details out of issue report ● Mark the issue as a vulnerability. ● Be prepared to work with Project Steering Committee (PSC) on a solution ● Keep in mind PSC members are volunteers and an extensive fix may require fundraising / resources If you are not in position to communicate in public please consider commercial support, contacting a PSC member, or reaching us via the Open Source Geospatial Foundation at info@osgeo.org. In case you stumble into a vulnerability: Responsible Disclosure
  58. 58. ● Bug stomp introduced in 2016 ○ Relying on volunteer time not working out ○ allowed developers to reserve time ● Moved to fixed schedule in 2017 ○ Arranging day each month too random ● Last Friday of each month ○ Check blog post for tips on participation You can join and help, too! Standing “last friday of the month” bug stomp
  59. 59. Thanks!
