Geodata Discovery Working Group

2007-08-30T22:05:57Z

Wiki-J: /* Regional data sets */

This is a [[Working Group]] started by the [[Public Geospatial Data Committee]].

''NOTICE'': There are two BOFs on this topic at [[OSGeo_at_FOSS4G2006#BOFs|FOSS4G2006]] on ''Geodata'' and about ''Geodata Discovery and Metadata Models''.

While OSGeo can consider hosting sets of public geodata, (and for the purposes of offering maintained [[Geodata Packaging Working Group|packages]] of high-quality data for education and demonstration, it probably will), we can compile a set of best practises and references to good prior art for building and maintaining collections of data and metadata.

== Focus ==

* Metadata for collections of geographic information.
* Providing best practise and prototypes for geodata search facilities
* Help with providing input into the OSGeo repository/services at http://osgeo.telascience.org/
* Providing 'catalog'/discovery/search services as part of OSGeo activities in promoting access to public domain and open licensed bodies of data.

Public Geospatial Data Project

2007-08-30T22:04:19Z

Wiki-J: /* Geo Data Repositories / Group Collection Projects */

There is an official [[Public Geospatial Data Committee|official foundation committee]] page which provides more detail on meetings and discussions.

== Mission ==

=== Promote the use of open geospatial formats ===
Providing best-practise guidelines and examples for use of open and free standards for data (GML, WMS, WFS-T) and metadata (Dublin Core, RDF, ISO19115 through ISO19139).

=== Promote public access to state-collected geodata ===

Lead by example in demonstrating economic value and research activity generated by open access to public geographic information.

=== Run a repository of open geodata ===
A [[Geodata_Repository]] shall be hosted by the PGDP.
Additionally, links to other open data repostories shall be collected.

=== Present and explain licenses for public geodata ===
The PGDP aims to collect licenses suitable for the publishing of public geodata. The license shall be presented along with a summary of its benefits and focus.

== Approach ==

After a [[Public Geospatial Data Committee Definition Phase|Definition phase]] this has become an official [[Committees|committee]] within [[Main Page|OSGeo]].

=== Working Groups ===

At the [[Geodata Committee Meeting 20060322|first meeting of the geodata committee]] we decided to focus interest through three [[Working Groups]]:

* A [[Geodata Discovery Working Group]] which would focus on indexing and search of data and metadata repositories.
* A [[Geodata Packaging Working Group]] to look at creation and maintanance of really high quality and rich data packages to offer for educational purposes with software packages, with [[GRASS GIS]] in particular.
* A [[Geodata Licensing Working Group]] to look into parallel licensing developments and to consult on guidelines for open licenses for geodata.

=== Mailing List ===

There is a public mailing list and [http://lists.osgeo.org/pipermail/geodata/ archive] for discussion of geodata activities within OSGeo at http://lists.osgeo.org/mailman/listinfo/geodata.

=== Meetings ===

This group is having regular meetings on IRC on the #osgeo channel on irc.freenode.net. At the moment this is happening on Thursdays at 16:00 UTC. [http://www.timeanddate.com/worldclock/fixedtime.html?year=2006&month=4&hour=16&min=0&sec=0 fixed time]

See the [[Public Geospatial Data Committee|Geodata Committee]] page for more details on past meetings and upcoming agendas.
