The '''Web Map Client Bird of a Feather (BOF) session''' (also referred to as the ''ka-Map/OpenLayers merger BOF'' or ''AJAX Map Client BOF'') at FOSS4G 2006 met from 1800 - 2000 on Wed 13 Sep 2006, with the intention of identifying common components that could be abstracted and shared between the various Free and Open web map client libraries.

== Summary ==

Christopher Schmidt posted a [https://mail.osgeo.org/servlets/ReadMsg?list=webmap-discuss&msgNo=119 summary of the meeting] to the [https://mail.osgeo.org/servlets/SummarizeList?listName=webmap-discuss OSGeo webmap-discuss mailing list]. (Note: You must be logged into the OSGeo site to join this mailing list.)

== Projects ==

The following projects (at a minimum) were represented at the BOF:

* [http://ka-map.maptools.org/ ka-Map]
* [http://openlayers.org/ OpenLayers]
* [http://communitymapbuilder.org/ MapBuilder]
* [http://www.mapbender.org/ Mapbender]
* [http://mapguide.osgeo.org/ MapGuide]
* [http://www.cartoweb.org/ CartoWeb]
* [http://worldkit.org/ WorldKit]

== Conclusion ==

The meeting participants agreed that the simplest and most effective place to start integrating code between projects would be to select a map tile display engine and abstract it into a library. The map and layer rendering core from OpenLayers was selected for this task. By the end of October, the OpenLayers team will spec out an API (tentatively to be called '''webmap.js''') and begin to split out the minimal necessary portions of the OpenLayers code base into this separate library. By that time, each of the participating projects (hopefully ka-Map, OpenLayers, MapBuilder, and Mapbender, at a minimum) will evaluate their needs for a core tile display API and offer recommendations on how best to design the webmap.js library to offer maximum utility to everyone.

== Notes ==

The following were the notes collected on the overhead screen during the meeting.

----

'''Possible Web Map Subsystems?''''

* Map display
* Layer
* Features
* Controls (UI widgets)
** Pan / zoom buttons
** Zoom bar
** Modal tools
** Link to this view
** Scale ratio
** Scale bar
** Ruler
** Measure area
** Legend generation
** Mouse actions
** Keyboard shortcuts
* Overlays

* Client-side vector drawing
** Zorn
** SVG
** VML
** Canvas
** digitization
* Printing (generating PDF on the server?)
* Server-side tile generation
* Coordinate projections
* Event handling (higher level map semantics? and/or lower level browser semantics?)
* Documentation!!!1! (lack thereof not a business strategy)
* Unit tests
* Framework issues??? or none at all
* XML processing
* Licensing? BSD/LGPL preferred for reusability

The map and layer rendering core from OpenLayers was selected for this task, due to its relative simplicity and modularity.

 Our hope is that, in the future, the new core display library will ultimately be integrated into each project, and be developed collaboratively between the participating projects thereafter.
